In 2026, with how much money their is in aviation, it seems wild to not have digitized this ages ago. The runway should be essentially 'locked' when in use, if they don't want screens in every ground vehicle that may cross a runway, at least display it at runway entrances.
That ATC still takes place over radio just seems insane at this point. And there's pretty much no way to make ATC's job not stressful, its inherently stressful. Taking out how much of their job is held in the current operators mind versus being 'committed' seems like low hanging fruit 30 years ago.
The whole system's just begging for human error to occur. There's 1700+ runway incursions a year in the US alone, each one should be investigated as if an accident occurred and fixes proposed. Like when an accident occurs.
While modernizing ATC in the US may be overdue, the real issue here is that ATC in the US has been understaffed, underpaid, and overworked for a while now.
My father works ATC and his schedule has him working overtime, 6 shifts a week, including overnight shifts, meaning that there is literally not a day of the week where he doesn't spend at least some time in the tower.
If that's the reality for even half of the controllers, it's no surprise that we've been seeing more and more traffic accidents lately.
In reality when these experiments were conducted the frog simply jumped out as soon as the temperature started to raise, frogs will not sit there in slowly boiling water and just die without trying to escape way before the water becomes dangerous.
No that is not the issue. Runway incursions have always been a problem and many deaths have occurred.
There have been many attempts to change phraseology, teach pilots and controllers to always readback runways, etc. but nothing that actually prevents the issue from occurring entirely via automation.
Okay, so then what is? Most jobs have this failure mode because there's a tendency to strip funding until disaster happens, even when it was clearly foreseeable.
What's impressive is that if you look at the issues PATCO struck over, it was basically identical to the problems ATC faces today. The problem being that everything has only gotten a lot worse for ATC controllers.
The union pretty loudly and early on pointed out major problems with that job and the response of ignoring them for 4 decades is what's driven us to the current situation.
A union that isn't allowed to legally strike when needed isn't a useful union though. The state that ATC has been in for the decades after that suggests to me that they were correct to strike.
That's like the argument about how we'll never (or should never) have self driving cars.
Clearly human-run ATC results in situations like this, so the idea that automated ATC could result in a runway collision and should therefore never be implemented is bad.
Imagine it were 90% automated. Now imagine there's a 3 hour outage of the automated system.
You're left with a bunch of planes in the sky that can't stay there forever, and not enough humans on the ground to manually land them.
Now image the outage is also happening at all airports nearby, preventing planes from diverting.
How do you get the planes out of the sky? Not enough humans to do it manually.
Now imagine the system comes back online. Does it know how to handle a crisis scenario where you have dozens of planes overhead, each about to run out of fuel? Hopefully someone thought of that edge case.
There's exceptions all the time. They turn back because a warning light came on. They saw a deer on the runway, a passenger got up to the bathroom. There's no way that could be automatic, plus they often need atc to look at their jet to see if it's damaged.
My suggestion is to restrict the use of smaller jets like crj and turboprops. I know airports like LaGuardia can't handle the big jets either, but they could reduce the slots and require a jet that holds, say, 150 people or more. This would result in fewer flights per day to some airports, but reduce overall congestion while still serving the same number of passengers.
Automating ATC is similar to automating flying in general. Even if it's possible to automate 99% of 99% of flights, including even takeoff and landing, commercial flights still have two pilots because if things start to go wrong there's just so many edge cases that you can't easily write automation to handle all of them. Same thing for ATC, except even worse. They still have control towers because controller eyeballs still work even if nothing else does, if ground radar fails, or if a vehicle doesn't have an ADS-B transponder, or if a crash eliminates the radios, etc. There's just so many edge cases that making automation be able to handle everything is extremely difficult
Air traffic (and ground traffic) control are not simple problems. La Guardia has 350k aircraft operations (takeoffs and landings) every year. 1000/day. Peak traffic is almost certainly more than 1 plane every minute. Runways are always in use and the idea that some simple software will solve all the safety problems is not grounded in reality.
This isn’t hypothetical, this system just exists in other countries. Digital systems can confirm flight instruction from ATC with zero radio communication.
I’m not saying we couldn’t move more into automation. What I’m saying is that doing so will not solve all of our air/ground control problems. We still have human pilots and humans driving vehicles on the ground. Switching from humans directing landings to machines might improve some things but will not solve for all (and probably not most) risks.
Literally the crash here was caused by a fire truck entering the runway.
The ATC told them to enter the runway because they were confused or distracted due t overwork.
No one here or anywhere is saying automation would solve or be able to handle everything that human operators handle, that's an argument you invented that no one is making.
People are saying automation could handle a significant portion of the routine things allowing humans to handle the more complex/finicky issues.
Even if automation could handle 10% of the most common situations it would be a huge boon. In reality its probably closer to 50%.
There's unfortunately an alertness problem WRT automated systems.
If the reason you have the human there is to handle the unusual cases, you run the real risk that they just aren't paying attention at critical moments when they need to pay attention.
It's pretty similar to the problem with L3 autonomous driving.
Probably the sweet spot is automation which makes clear the current set of instructions on the airport which also red flags when a dangerous scenario is created. I believe that already exists, but it's software that was last written in 1995 or so.
Regardless, before any sort of new automation could be deployed, we need slack for the ATC to be able to adopt a new system. That's the biggest pressing problem. We could create the perfect software for ATC, but if the current air traffic controllers are all working overtime and doing a job designed for 3 people rather than one, they simply won't have the time to explore and understand that new system. It'll get in the way rather than solve a problem. More money is part of the solution here, but we also need a revamped ATC training program which can help to fill the current hole.
> The ATC told them to enter the runway because they were confused or distracted due t overwork.
Very possibly. It will be interesting what comes from the investigation.
> No one here or anywhere is saying automation would solve or be able to handle everything that human operators handle, that's an argument you invented that no one is making.
I’m asking if it would have solved even the current situation. The truck presumably saw the red light, and was asking to cross. Would traffic control have said no if more had been automated and if so, what automation would fix this? Unless we are supposing the truck would be autonomously driven and refuse to proceed when planes are landing, in which case, maybe, though that’s not really ATC automation anymore.
an automated system that could check if a plane is about to land on a runway and show some kind of alert or red light is hardly a stretch of the imagination
I'm pretty sure the amount of data isn't the problem here. Maybe it's the number of corner cases? You would still want some human-in-the loop with quality UI for ATC.
There are plenty of stories of ATC helping to guide pilots back to the ground after an engine failure or after a student pilot had their instructor pass out on them or something like that.
Even if most of the work is routine, you definitely still want a human in the loop.
It's worth pointing out that plenty of pilots take off and land safely at uncontrolled airports. ATC is a throughput optimization; the finite amount of airspace can have more aircraft movements if the movements are centrally coordinated. It feels like we are nearing the breaking point of this optimization, however, and it's probably worth looking for something better (or saying no to scheduling more flights).
The FAA already does issue temporary ground stops for IFR flights when ATC capacity is saturated. This acts as a limit on airlines scheduling more flights, although the feedback loops are long and not always effective. The FAA NextGen system should improve this somewhat.
A third runway for Heathrow was formally proposed in 2007 and is projected for completion in 2040. This is an airport so overburdened people are buying and trading slots.
This isn't a Kubernetes cluster where you can add VMs in 30 seconds.
>> Software routinely solves database coordination problems with millions of users per second.
A naive view that confuses the map with the territory.
While in a database state you write a row and reality updates atomically....for aircraft they exist in a physical world where your model lives with lag, noise, and lossy sensors, and that world keeps moving whether your software is watching or not. Failed database transactions roll back, a landing clearance issued against stale state does not. The hard problem in ATC is not coordination logic but physical objects with momentum, human agency, and failure modes that do not respect your consistency model.
But context is important. "Low-hanging fruit" doesn't mean the solution is "easy" in a vacuum, it just means this specific aspect is the easiest and/or most obvious place to start attacking a problem.
Or to stick with the language of the analogy, every fruit tree has some fruit that is lower than the others. That doesn't mean all "low-hanging fruit" is within arm's reach of the ground, some fruit just doesn't require as big of a ladder as other fruit.
This comment isn't a judgment of this specific case. I don't know enough about ATC to have any confidence in my opinion on the viability of replacing humans with software.
I think you're mistaken. That whooshing sound must have been my comment flying over your head.
That was my first comment in this thread, so there was no established goal to change. My sole goal was to clarify the meaning of an idiom that the comment I was replying to was misstating.
I even included a disclaimer that "This comment isn't a judgment of this specific case", so I don't know how you could have received it as such.
You can't just throw software at this. It's a complex system that involves way more than just an airplane and someone in a tower. Systems engineering, human factors, and safety management systems are the relevant disciplines if you'd like to start reading up. In addition there are decades of research on the dynamics between human operators and automation, and the answer is never as simple as "just add more automation." Increased reliance on automation can paradoxically decrease safety.
CPDLC is already being deployed domestically. It's currently available to all operators in en route segments.
All runway incursions at towered airports are reported, classified according to risk, and investigated.
On the flipside, look at the success of TCAS. It doesn't have a perfect operational history. It hasn't completely eliminated midairs, either. But it took a relatively rare event and further reduced the frequency by about a factor of 5.
I wouldn't be so quick to rule out that there's some kind of relatively easy technological double check that could greatly reduce incidents. The fact that we've not gotten there despite years of effort to reduce runway incursions doesn't mean that it's not possible.
TCAS is fantastic - absolutely stellar example of effective automation.
But calling a replacement of major ATC functions with software a "simple fix" is a perfect illustration of why this is a bad idea. Nothing about human-rated safety-critical software is simple, and coming at it with the attitude that it is? In my view, as an experienced pilot, flight instructor, spacecraft operator, and software engineer, that thinking is utterly disqualifying.
Besides, there already are a lot of "simple" fixes in place for this problem, e.g. RWSL, which didn't prevent this accident.
I don't know. At some point, you need to do all the systems engineering. But "why not just ......" is a perfectly reasonable place to start looking at a problem and sometimes the answers really are that simple.
> Besides, there already are a lot of "simple" fixes in place for this problem, e.g. RWSL
It'll be interesting to hear why RWSL didn't help, as it is supposedly deployed at LGA.
> The runway should be essentially 'locked' when in use, if they don't want screens in every ground vehicle that may cross a runway, at least display it at runway entrances.
It does, the Runway Status Lights System uses radar to identify when the runway is in use and shows a solid bright red bar at every entrance to the runway. I'm curious what the NTSB has to say about it for this incident. From the charts LGA does have RWSLs. I didn't check NOTAM to see if they were out of service though.
Emergency vehicles almost always can override/ignore warning devices (think firetrucks running red lights) which can cause "fun" for some value of "death/dismemberment/vehicle loss".
Airport emergency services are presumably trained in this, but since a plane cannot stop easily (or not at all on takeoff after V1), I seem to remember the general rule is that even emergency vehicles with lights and sirens on give way to planes, and don't enter runways without permission from the tower.
In the audio released by the BBC, the fire truck DID get permission from the tower to cross something, I can't tell if it was the runway in question. However, to cross the red runway lights if lit, you normally need that spelled out too something like "truck one, cross four delta, cross red lights". This did not happen on the BBC audio, which could mean one of many things.
They got clearance, which was overruled by a STOOOP!
The guy was alone operating 2 frequencies, had an emergency of another aircraft going on… is not so easy as many commenters from the armchair are insinuating
They got clearance and then obviously didn't bother to look outside, which is a dereliction of the basic responsibility of operating any vehicle on an airport surface. Clear left, clear right, then cross the hold short line.
(See my other comment below if you're tempted to say something about visibility.)
They could not see, because delta crosses in diagonal to the runway, such that the plane comes from behind (and the right side) so the driver has no chance to see. The truck was moving fast which is ok, because you want to clear the runway as fast as possible.
From where I'm sitting, it's not really "the fault" of ATC (even though it is) simply because I'm not trusting enough of ATC even when they're on "my side".
When cleared across a runway I'm still going to be looking in all directions, and proceed as fast as I can. I also look both ways at railway crossings even if the guards are up and silent.
No. it wasn't. Delta crosses 04 in diagonal, so basically they should have taken the head out of the window and look behind. They had the clearance, so they just tried to cross. The problem is for some reason they did not hear the "Truck 1 stop" call.
All vehicles can override/ignore warning devices. Doesn't make it right. Emergency vehicles should not override/ignore train or plane crossings. Trains and Planes don't care about flashing lights. Crossing an active runway requires clearance for safety.
In this case, from the available information, the drivers of the fire truck thought they were cleared, and proceeded to cross while a plane was cleared to land. I'm not familiar with ATC ground radio to know if they were actually cleared or not, but it seems clear that that the drivers thought they were cleared.
How would you exactly "digitize"? While that sounds like a nice idea in theory it's the same as "digitizing" road traffic.
In the end the air traffic system is a highly complex but also a highly reliable system, especially when you compare accident rates.
I am sure the working conditions of ATC staff might be improved - but being both a pilot and a programmer, I know that there is no easy digitalization magic wand for aviation.
I'm sure the NTSB report will cover why this didn't stop the accident. Presumably either the system wasn't working as-expected, or the fire truck proceeded despite the warning lights since they had clearance from the controller.
The system is only advisory at present, so if the truck did see a warning light and proceeded anyway, they were technically permitted to do so.
>In the end the air traffic system is a highly complex but also a highly reliable system, especially when you compare accident rates.
1700 incursions a year, and other articles mentioning multiple near misses a week at a single airport [1]. It is safe in practice, likely largely due to the pilots here also being heavily trained and looking for mistakes, but it seems a lot like rolling the dice for a bad day.
>I am sure the working conditions of ATC staff might be improved - but being both a pilot and a programmer, I know that there is no easy digitalization magic wand for aviation.
I didn't say it'd be free. Just hard to believe radio voice communication is the best way to go.
> While that sounds like a nice idea in theory it's the same as "digitizing" road traffic.
Traffic lights instead of mad max intersections are better.
Then there's subway Automatic Train Control.
I don't know that Air Traffic Control staff don't have computer systems for establishing which plane owns what airspace. They at least did do it manually already following specific processes, so it can be at least augmented and a computer can check for conflicts automatically (if it isn't already). And, sure, ATC could still use radio, but there could be a digital standard for ensuring everybody has access to all local airspace data. Or maybe that wouldn't help.
Your ground vehicle wanting to cross a runway could have the driver punch "cross runway 5" button (cross-referenced with GPS) and try to grab an immediate 30 second mutex on it. The computer can check that the runway is not allocated in that time (i.e. it could be allocated 2 minutes in the future, and that would be fine).
But, as pointed out elsewhere, obviously some of this is already present: stop lights are supposed to be present at this intersection.
It's already digitized, he's clueless. The ATC knows where vehicle was and where the plane is going, it looks as simple case of mistake or maybe not watertight enough procedures
I'm sure they've started all of this a few times over the past decade. The problem is in the US if you can't start and finish a project like that in less than 2 years then it's effectively dead in the water. The last time we "modernized" ATC was closer to the 90's than today, when there was still some general political will to make our government agencies modern instead of tearing them to pieces.
There are systems for it, just not really integrated into emergencies and ground vehicles. Mistakes also happen even if all info required to avoid is present
But in the highly dynamic environment of final approach, landing, and taxiing, I doubt it would be practical. Unless we want to try autonomous 'driving' on taxiways and runways?
> There's 1700+ runway incursions a year in the US alone, each one should be investigated as if an accident occurred and fixes proposed. Like when an accident occurs.
How many runways crossings are there in a year? How much is "1700+" a percentage of that total?
A "runway incursion" is a very broad term that includes everything from this accident to a single engine Cessna moving past the hold short line prematurely at a quiet airport.
FAA defines it as "Any occurrence at an aerodrome involving the incorrect presence of an aircraft, vehicle or person on the protected area of a surface designated for the landing and take off of aircraft." [0]
Many runway incursions run no risk of any accident, but are still flagged as issues, investigated, and punished if appropriate.
The point is that it doesn't matter what percentage of the total they are, it's that 1 is too high without adequate explanation (the Gimli Glider caused vehicles to be guilty of a runway incursion by turning an abandoned runway into an active one, for example).
And the cost of investigating 1,700 should be within the budget.
Of course it matters. All of these entities have limited budgets and personnel and almost unlimited ways they could apply those resources. They have to choose what to chase and they do that by deciding how big of a problem it is.
If 1,700 is a huge percentage of runway uses (obviously it isn't but grant it, say at a single airport), then it's mandatory it be investigated because it's so huge.
If 1,700 is a minuscule fraction of all runway uses (as it likely is) then investigating it should be a proportionally minuscule amount of the budget.
Given there are ~45,000 flights per days in the US (and so aircraft and vehicles would move hither and fro around an airport for each flight), 1700 feels like a small number.
Exactly - it's a small number and should be investigated, because if we reduce the number of all incursions, we reduce the number of collisions (and fatalities).
They are classified as operation/ATC error, pilot error, and vehicle/pedestrian error.
Human can misspeak or mishear instructions, but if they were communicated and understood correctly (a read back was correct), but the pilot had a 'brain fart' and went forward instead of stopping, how do we eliminate brain farts?
NOTE-
Previous reviews of air traffic events, involving LUAW instructions, revealed that a significant number of pilots read back LUAW instructions correctly and departed without a takeoff clearance. LUAW instructions are not to be confused with a departure clearance; the outcome could be catastrophic, especially during intersecting runway operations.
The older term was "hold short runway X" and that was too close to "hold runway X" - the first meant do NOT enter the runway, the second meant enter and line up but do NOT takeoff.
You can't know how big of a problem it is without an investigation. Frequently, the initial "obvious" cause of a collision or incursion turns out to be a multi-layered set of failures. Tightening up procedures or recognizing a previously overlooked defect in the systems makes us all safer and should be prioritized.
We talk about Vision Zero for streets. Vision Zero is actually achievable in aviation.
You seem to be giving too much credit to the singleton design pattern. We know exactly how well that works on a modern, multi-tasking, preemptible operating system (hint: not well at all).
> That ATC still takes place over radio just seems insane at this point.
Voice communication is insane? I suspect you are ignorant of what it is like to actually fly a large aircraft into a busy airport. Fault-tolerant and highly available hardware must facilitate low-latency, single-threaded communication with high semantic density in order to achieve multi-dimensional consensus in a safety-critical, heterogeneous, adversarial environment.
Listening to some recent close call ATC tapes, yes, it seems absolutely insane to manage current traffic levels with the existing number of controllers over voice.
I don't doubt that it's a very safe system with enough slack allowing for intentional redundancy. But as it is, some of these controllers seem to be limited by their ability to pronounce instructions, leaving absolutely no margin for error and presumably very little room for conscious thought.
Voice communication has the advantage is that it can be used without taking off hands and attention off controls. Digital solution would require using device.
Voice communication can still be used for anything out of the ordinary despite automating the common case.
Almost all voice transmissions are routine instructions/clearances from ground to air, with the pilots reading them back to reduce the chance of errors. In fact, this already exists and is in wide use in (at least) the US, EU, and in transoceanic airspace.
Of course, now you have two systems that can fail, and reducing reliance on the older one can easily cause automation complacency (which is a well-researched source of errors) and require more frequent refresher courses if the skill is not practiced on a continuos basis.
I suspect that that these are the reasons it's not commonly used for approach and tower operations: There's a lot more spontaneous and/or nonstandard stuff happening in those flight phases, and as you say you don't want a pilot's eyes on a tiny screen/keyboard instead of on their instruments or out the window.
Captain Steve breakdown: https://youtu.be/Hx-GFeErXD8?si=iND_BkDrtGNapB7Q His videos are pretty insightful and always respectful. Highly recommended. Expect him to have new videos as more information becomes available.
ATC recording on https://www.liveatc.net/recordings.php
Fire truck was cleared to cross and then told to stop. I'm not sure if they were the only controller working at the time, they continued working after the incident which seems unusual; my understanding is normally they'd be relieved by another controller.
Which, as a non informed person but someone who needs to travel by plane, sounds absolutely insane. Was it always possible to staff that with a single person or is that a result of understaffing?
As an informed person (PPL flying single engine into smallish towered airports all the time), it is absolutely insane for an airport the size of LGA. Occasionally, you will encounter one guy doing tower and ground at very small class D airports or during not-so-busy shifts.
To play devil's advocate, ASEL into small deltas is significantly different than receiving full-stop IFRs late at night.
This small mistake (and it is initially small, just catastrophic) is a system breakdown, not necessarily a staffing breakdown. Though staffing is definitely a wider issue in the NAS.
Edit to add: looking at this incident closer it appears LGA was busy enough to make a single tower/ground controller an obviously bad plan. Still, systemically, there's enough low hanging fruit here, like ADSb in for the airport trucks or hold short line guard lights. I hope the takeaway isn't just "don't have controllers make mistakes".
Yea, if you listen to the ATC audio, you can hear that in addition to the normal high workload of handling both ground and tower, this guy had an emergency aircraft on a taxiway to deal with, too. A lot of holes in the swiss cheese lined up, but one of them clearly is ATC workload.
Speaking very generally, it's not unusual at all. Tower and ground are combined all the time - at smaller airports.
Should they be combined at LGA when both (crossing) runways are in use, and there's an incident on the field? (The fire trucks were on their way to investigate a smell on the flight deck of another airplane that had to abort takeoff twice.)
I fly out of a small-to-medium-sized airport in Canada and I've never seen it happen there. The idea of one person being responsible for both tower and ground in the busiest airspace in the US is absolute insanity.
That seems unusual to me. It’s common at smaller airports, but for a big one like LaGuardia I’d think tower and ground would be two different controllers, even lateish at night like this was. I know there has been a staffing problem for controllers in the NY area for some time.
It's not unusual for airports to reduce staff at night, and the incident occurred at 23:36 local time. Even at a very large airport in a very busy traffic area, one controller can probably handle normal operations at this hour.
The obvious problem is what happens when operations become abnormal. ATC shouldn't be staffed for normal operations, because then abnormal operations lead to catastrophe. Welcome to last night: the weather is bad, which causes a plane to abort two takeoffs, which causes that plane to need emergency services. This increases the controller's workload beyond his capacity, so he accidentally clears the emergency vehicle to cross in front of a landing airplane, and they can't see the airplane because the weather is bad, so they follow the instruction and promptly get hit with an airplane.
When some bad weather can be the difference between "this is fine, one controller can handle it" and two dead pilots, you need to be staffed for bad weather.
Reddit aviation groups are full of professional pilots, saying how terrified they of flying into La Guardia or JFK, recounting close calls, with one saying how he avoided those two for 10 years...
But think of the money they saved by not having to pay another air traffic controller! A controller's yearly salary is the cost of about 10 seconds of the Iran war, based on the recently-reported figure of $11.3B for six days.
I don't think it's money. I think it's requirements and training pipeline restraints. The system is predicated on being able to throw bodies at the problem, but there is a distinct lack of qualified individuals to back that up. Personally, I didn't realize ATC as a possible career path until I was 36-- imagine my surprise when I found that I had already aged out.
Who would want to work that job once they find out what the day-to-day is like? I had an intern who looked at that out of the Air Force but he found out what you get paid and what the expectations are for the job and he figured he'd try his luck on something easier and better-paying like life-preserving medical devices. On a related note, why do you think nobody who you'd actually want teaching public school actually teaches public school in the US?
It’s not a money thing. It’s a shortage of people who are mentally able to do the job mixed with terrible hours and early forced retirements. ATC school has a failure rate of over 50 percent.
It's partially a money thing. ATC is under-compensated. They'd get more - and more talented - people interested if the money made up for the stress, hours, and early forced retirement.
> I'm not sure if they were the only controller working at the time, they continued working after the incident which seems unusual; my understanding is normally they'd be relieved by another controller
I remember late last year, couple of months ago, US ATC controllers were without pay but forced to work anyways (similar to TSA I suppose, although I don't think they were forced, but volunteered to work without salary), is that still the situation? Couldn't find any updates about that the situation been resolved, nor any updates that it's ongoing, if so though it feels like it'd be related to the amount of available controllers.
ATCs weren't exactly forced to work: they aren't slaves and are free to quit any time. But if they didn't show up for assigned shifts even though they weren't getting paid then they were subject to disciplinary action including termination. Some of them called in sick, or took on temporary second jobs to bring in some cash (obviously a bad thing from a fatigue management standpoint). After the government shutdown they were paid in arrears for all of the hours they worked. It's crazy that Congress plays political games with essential services like ATC.
The US has had trouble keeping enough controllers. It's a skilled but extremely stressful job, and so retention would always be difficult but the US also works hard to make it suck more than it should, and of course the over-work from not having enough people makes that even worse.
But no, AIUI only things that were somehow deemed part of "Homeland Security" are frozen, the TSA are part of Homeland Security but the ATC are under the FAA. So this particular partial government funding lapse wasn't causal, at least directly.
Specifically, Reagan made a point to cut our nose to spite our face just to not pay ATC workers more money. For political and Ideological reasons.
So why the fuck would any talented individual choose to go work for the "Get an example made out of you" department, on top of the horrific stress of the actual job!?
The idea of a union that "isn't allowed" to strike is a joke. Next will be a union that has a max membership of 1!
The budget was signed Feb 3 this year to fund most of the govt (excepting DHS) through September 2026. ATC were not paid from Sept 30, 2025 until Feb 4, 2026. They receive back pay. They are also supposed to get a raise and funds set aside to hire 2500 more ATC but that is currently held up in the DHS funding fight.
Utterly unqualified to suggest any causes (wait for the NTSB report on that), but couple compounding factors I've read elsewhere to begin to understand the situation and context:
- Another plane was out of position, grabbing some attention of the controller
- Stop communication was ambiguous about whether talking to previous plane or firetruck
- The colliding plane didn't have "explicit" landing clearance, but a "follow previous plane and land the same way unless told otherwise" implicit landing clearance. In Europe, planes need an explicit landing clearance, the act of granting it may have brought attention to the runway contention. US implicit system (arguably) is a bit more efficient, debate will now be is it worth it (pilots are now required to read back instructions because of past blood... will this result in same thing?)
- This was around midnight and apparently a little foggy, making visual contacts harder
Remember folks, disasters like this are rarely caused by a single factor. NTSB reports are excellent post-mortems that look at all contributing factors and analyze how they compounded into failure. Be human here.
> Stop communication was ambiguous about whether talking to previous plane or firetruck
"stop stop stop, truck 1 stop stop stop" I mean maybe it was ambiguous for half a second but he pretty quickly said "truck 1 stop". I guess we'll have to wait for the sync up to see if it was too late to stop by then
In Europe is illegal to capture and publish ATC. I don't understand why. Anyway I do not know what are you comparing.
From pilot friends, in best case I would say a big “depends” in some countries are very unprofessional, in others very professional (anyway total unfair generalization). There were already accidents because of that, for example because the twr communicated with locals in non english, so not everybody was at the same page.
Emergency vehicles were en route to another emergency in progress on the other runway. Sadly it sounds like a fire truck was cleared to cross the active runway moments before the CRJ landed. By the time the controller realized that mistake it was too late.
I'm very, very curious about whether the ARFF crew visually cleared the runway and final before crossing the hold short line. It's standard procedure for flight crew to do this, specifically to mitigate the risk of ATC errors.
Reports are there were fog and rain at La Guardia at the time of the incident. They were on a short final, and it’s entirely possible they were not visible to the fire truck’s crew.
I have over 1,000 hours as PIC in the NY area alone, in all seasons and all weather, and I was in the region last night, awake when the accident happened. LGA was reporting 4SM -RA BR FEW045 BKN090 OVC110 at the time of the accident. The weather wasn't anywhere close to what I'd call "bad" here. Sprinkles and some high clouds.
I can almost guarantee you the airplane was visible from taxiway D.
Yes ARFF should still look before crossing, but the weather wasn’t great with limited visibility and thus even if they looked it’s possible they didn’t see anything.
Was curious if ground vehicles at airports also use transponders to communicate position to the radio tower, and it turns out the FAA put out a report last year on potential solutions to avoid this exact situation:
The only negative I can think of is that it will generally involve accepting and responding to clearances on short final. I think adding more tasks to that critical stage of flight probably increases danger a little. Especially for low time student pilots like myself. That's particularly relevant in the U.S. because we have a higher percentage of student and private pilots than most of the world.
Overall, though, I'm fully convinced this would be safer.
Transponder doesn't alter the laws of physics for the landing plane you just cut off. I guess it gives ATC a ~5sec jump on telling some other flight to go around.
I'd bet a lot of money that however the system is implemented the police and fire get special treatment when it comes to process (i.e. asking permission before they go somewhere planes might be) and that is part of what lead to this.
> I'd bet a lot of money that however the system is implemented the police and fire get special treatment when it comes to process (i.e. asking permission before they go somewhere planes might be) and that is part of what lead to this.
I highly doubt that any system would intentionally give ground vehicles of any kind special treatment on an active runway.
The trajectory of the plane is obvious enough that it should be able to predict where it will likely be in 30 seconds or a minute. You can't cheat physics, if it is going down in direction of runway, it is landing or at worst will do go-around, so the services should be alterted runway is no-go automatically
> Captain and first officer are reported to have died in the accident, two fire fighters on board of the truck received serious injuries, 13 passengers received injuries.
He asked the truck to stop multiple times. That's got to be so stressful and annoying - knowing you asked the truck to stop, but for whatever reason the command wasn't received.
The shortage of ATC staff dates back to the Clinton Administration. It’s just hard to attract people into a 5+ year training program for a very stressful job where you might get bounced near the end with no payout and no transferrable job skills.
No the shortage goes back to Regan when their justified strike was busted. It ended the PATCO “union” and was a negative turning point for labour unions in general.
I think you mean Reagan. He removed the union for the ATC not Clinton.
Honestly, you can generally just blame Reagan for about anything. A presidency about weaking labor, strengthening Iran, and ballooning the deficit is uh never going to leave good traces.
Reagan did the right thing in that case. Government employees should never have collective bargaining rights. Public employee unions are contrary to the interests of taxpayers.
People complain about police unions all the time, it's just their complainants don't overlap much with the people who complain about private sector unions.
Over the course of the past year, I think we've seen more evidence that the federal workforce's collective bargaining rights aren't strong enough. Workers' employment contracts are being ignored, employees are being threatened, constructively terminated, all in an attempt to enact RIFs without following the law.
Things are happening to the federal workforce right now that aren't even legal in the private sector.
You have to have your contract violated for a significant amount before you can notionally afford to hire a lawyer to fight it out. Below 5 figures it doesn't make much financial sense to do that for most people, so they just eat it instead. It's how a lot of "theft of wages" and other mistreatment happens so often. Lawyers don't take those cases for free, and court isn't free either. And you're not going to instantly appear at the top of the docket for something small like that especially if the government buries you in procedure. They can do that for years.
But sure, yeah you can seek redress through the courts.
Suing the federal government solo is an insurmountable task for most people -- even more so while they're being constructively terminated. Employee unions have been suing on their workers behalf over the past year, but the executive branch can drag out federal trials for a lot longer than people can stay without a job.
Yes, absolutely. No government employees should ever have collective bargaining rights. If they want better wages and working conditions then they can advocate for those through the political process, the same as any other citizen.
Collective bargaining rights shouldn’t even be a separate thing. They’re just a natural consequence of the fact that free speech is protected and slavery is illegal. The idea of an illegal strike is bizarre.
ATC/GTC seems like a really strong candidate for partial automation with recent advances in AI. Obviously we'd still want some expert humans in the loop for exceptional situations, but I have to imagine there's a way to significantly reduce the cognitive burden/stress for these folks.
Recent advances in AI aren't useful for routine operations in safety critical domains such as aviation because we don't know how to verify and test them. An LLM is effectively an unpredictable black box with unknown failure modes. There is opportunity for greater automation but probably based on classical deterministic programming.
Yup, it's been a problem ever since Regan (a Republican) fired over 11,000 ATC employees. And by "anyone" ITYM "republicans" again, because Democrats have been trying for years.
"”The truth of the matter is that my policies are so mainstream that if I had set the same policies that I had back in the 1980s, I would be considered a moderate Republican,” - Barack Obama [0]
This is not a statement of Republicans and Democrats being the same, but a statement of Republicans going off the deep end in during and after Reagan.
Obama was a very moderate Democrat for his time. If you go back in time a moderate Democrat and Republican were similar because the "center" was more reasonable. Now the "center" is just people that are ashamed that they vote Republican.
If we accept that, then "government" and "Republicans" would be pretty much synonymous, so my original point stands. (Not that I accept it, but even if I did.)
Another option: they shouldn't be government employees at all. It would be much better for them to work for the actual airports themselves and be certified by the government or a private testing organization instead.
Which government? State, Federal, City, or a Port Commission? There is in fact a significant distinction between the responsibilities and capabilities of each of these levels of government and you can't lump them all together. My home airport is operated by a port commission, which is government, but the port commission's task is to operate the ports.
>There is in fact a significant distinction between the responsibilities and capabilities of each of these levels of government and you can't lump them all together.
But all private businesses have the same responsibilities and capabilities and therefore can be lumped together as one entity? The asymmetry in how you're critiquing the way this is discussed ends up revealing your bias.
> our civilization relies upon workers to shoulder the burden everyday.
Our civilization? Nah. Just that one shithole country. Greatest country in the world and they schedule a single guy to work both tower and ground frequencies at a major airport, it's almost like they're asking for this shit to happen.
And before anyone mentions understaffing, this literally one of the plethora of problems that the rest of the world figured out while the U.S. continues to act special.
I'm curious about what kind of visualization does the ATC have at the disposal about the current occupancy of the individual tarmac segments? I'd assume if an airplane is approaching for landing on a specific runway, that runway should have been clearly marked as restricted for access until the plane would actually land and clear it?
In the US, airplanes can be cleared for landing while the runway is occupied (you can be number two, three, etc. for landing and still be cleared). It's different in other countries, where you can only be issued a landing clearance if the runway is clear or anticipated to be clear before you land (e.g. the plane before you is already exiting the runway).
The way it's supposed to work, the ground controller first verifies that there are no traffic conflicts before clearing vehicles to cross an active runway.
Gravity. The aircraft is heavier at the back, where the engines are. With the nose severely damaged/missing, the centre of gravity has shifted aft, so what’s left of the nose is sticking up in the air.
I’d guess the front landing gear assembly is going to be fairly heavy, and appears to be missing. This model of plane also has its engines at the rear, not under the wing, which will move the balance to the back.
Planes typically have their center of gravity just forward of the rear wheels. This makes it easier to rotate on takeoff.
The margins are thin enough that certain planes will sometimes have people in the back get off first, before the people on the front, to avoid tipping onto the tail like this.
The entire cockpit, front toilet and galley area, and probably a front row seat have all been utterly destroyed. Unfortunately I'd be amazed if the death toll stays at two.
Are the increased number of air incidents since Dec 2024 reflective of anything real or is it more attention on something? Brigida v. USDOT comes to mind but doesn't seem relevant. I'm sure we could all construct a chain of "this thing happened that caused that which caused this" and so on, but I'm curious if someone has done the effort to see whether such a chain is defensible.
Also, did the pilots die in the collision or in some sort of aftermath? The cockpit looks absolutely smashed.
You can probably construct a realistic chain of failure that goes all the way back to political tomfoolery and bad air traffic control leadership/staffing decisions, but that makes the wrong people look bad, so they'll probably blame individuals further down the totem pole like the controller or pilot and call it a day.
This comes to mind how during the Boeing news scandals, commenters would confidently argue "Flying is still ridiculously safe, statistically speaking", "these things happen every day, just underreported", and "you/people are irrational for not flying Boeing". It's a very curious argument to me. Is the ATC infrastructure issue analogous or not, etc.
Maybe US media, hardly an unbiased news source about US events, especially when hundreds of billions are flying around about incompetent massive employer and lobbyist.
Nowhere else in the world you would hear such statements. Boeings simply disappeared from Europe, those few that were here before. I am sure they are still used somewhere but I haven't flown any in past 7-8 years. Heck, I haven't seen any in South east Asia neither (but that may be due to luck).
I check this with all bookings, no way I am flying that piece of shit if I can anyhow avoid that, not alone and quadruple that with family.
That is just simply false. There are many boeings flying in europe. Just by randomly clicking around on flightradar24 I found multiple right now in the air.
It is strange. What is importa t is, are things getting better or getting worse? As they say, it’s not the fall that kills, bit the impact. Are we falling?
It should be noted that aircraft and all other vehicle and personel movements on an airport are controlled from the airtraffic control tower by air traffic controllers or
directly by individual flaggers, as directed from the tower.
Or at least thats the way it is supposed to work, and of course the operation at a place like LaGuardia is more complex, and will have specialists and multiple zones.
What will put an extra edge on this is the
whole ICE thing, and airport chaos pulling the roof down.
> What will put an extra edge on this is the whole ICE thing, and airport chaos pulling the roof down.
How would the ICE thing cause more ground traffic collisions. Are you thinking ATC controllers are illegal immigrants and they’re going to run away during their shift? I just don’t see a connection there…
Not the crash, but the aftermath. Passengers will be showing up for flights today, nervous with the crash on their minds, and many will then encounter untrained goons cosplaying as airport security.
This incident caused delays and cancellations that ripple throughout an already understaffed network of TSA checkpoints. ICE presence will make airport security somehow an even worse experience for brown people.
The fire truck was flipped and moved to the side of the runway, this was not 24mph. 24mph is the final groundspeed recorded after the aircraft skidded off of the runway.
Per the ADSBx track the plane was at 101kts (115 mph / 185kph) just before crossing taxiway D, which would be where it hit the firetruck. It still had enough energy afterwards to reach taxiway E, 600ft away.
The results seem on the high end but they check out at first glance.
A plane is basically a flimsy tube. A firetruck is a solid brick comparatively. The plane out weighs the fire truck by a lot and out speeds it by a lot. So yeah, destroying the whole front of the plane to punt the truck it sounds about right for a 25 on 5 or 35 on 10/15 type rear ending to me. Flipping doesn't really sound that unreasonable considering that the plane made contact with the top of the truck (just by virtue of comparative height) and contact may not have been straight on. Even if it left the pavement on it's wheels airport firefighters aren't exactly who I'd bet on (they're middle of the pack) to keep the truck on it's wheels if they got surprise kicked off the road especially if there's an embankment involved.
Pause the video at 13 sec. That firetruck is awfully intact for something that allegedly got hit at high speed. Basically just a bunch of top side sheetmetal damage (concentrated to the rear, obviously). In any case it didn't even get sent hard enough to screw up the cab exterior. And on the flip side, if you keep cranking the speed up you start getting to where the plane starts looking too suspiciously intact. There's just not much room to work backwards from the apparent results and get a high difference in speed or get very high initial speeds (100 onto 75 or whatever). If the plane was going fast the truck had to be going fast too or there'd be more carnage. But if they were both going fast you'd expect more damage from the after the fact barrel roll and the plane and truck to be a little farther apart in distance.
Fire truck is filled to brim with gear and doesn't care all that much about weight, plane is the opposite of that, lightness is money, so it makes sense fire truck looks better after crash than plane
The back of a firetruck is not a working implement like a dump truck is nor is it sufficiently strong for mounting a crane or man bucket like utility bodies often are It's a bunch of sheetmetal boxes to hold stuff and cover stuff and there's a water tank back there somewhere. In the middle down low some pumps are buried. Basically don't think of it as being any more structural than a box truck body because it's not. All that stuff got shredded, obviously, since they're only really meant to bear their own weight and were subject to all the truck tossing forces here. Beyond that the truck is in pretty good shape. It's not uncommon for a good "off the highway and into the ditch" crash to rip tandems off, twist frames, etc. None of that has happened here. The plane is pretty rough, but that's expected. They are 100% tin cans. Ground equipment moving at idle speeds will absolutely shred them before the operator even feels resistance. A goose hit square on the leading edge of a small jet's wing will put a massive dent in (and apply red paint, lol).
24 sounds about right for a closing speed for plane onto truck. Whatever the baseline speed of the truck was cannot have been that high or the truck would be absolutely shredded from the barrel roll and as it stand the cab is barely pushed in.
The last recorded ground speed data of 24mph also shows a wildly different heading (going from 30deg ish to 170ish). So it probably happened after the collision and was part of its deceleration. As far as I know, the truck would have been crossing the runway so the effective speed perpendicular to the plane would be zero except for directional shear I guess.
The speed was much higher per sibling comment, but also remember that kinetic energy also involves mass (planes are heavy) and the square of the velocity.
It looks like that is based on the last recorded speed from flightradar24[1] which was 21kts(24mph). The previous data points were 11kts, and 58 kts(the last point before the track deviates off the runway). I do think it is likely that the collision occurred at a speed faster than 24mph.
edit: Looking into this a bit more it looks like the plane came to a stop around crossing E while the emergency vehicle was crossing at D(based on ATC recordings). Using the following map as reference[2], the 58kts point was around E, while the previous recorded point which was just before D was 114kts.
On other hand planes are really not designed to be crashed into things. Only for limited impacts. So we might not have right comparison for relatively thin and aimed to be light structure being impacted by bulkier object.
Speed doesn't cause damage. Momentum causes damage. We understand speed, we do not understand momentum. It makes sense given our evolution.
People into boats need to understand this. Even a boat that travels no more than 4mph can crush you easily. This is why you never get on to moving boat from the front. Many people have made a mistake because speed is not high.
Tugboats bump other boats all day. Hundred thousand pound pieces of machinery bury themselves into the dirt. All this as part of normal operation. It's not that simple.
Speed, kinetic energy and acceleration are all interrelated and at the end of the day it's all forces (to some extent) and no amount of hand wringing commentary is going to replace genuine understanding of them.
/r/xyz doesnt need to fact check. Sure those are excellent subs but just being watering holes and not legal entities they can move faster. There were some wrong facts on r/aviation although it got viral so people just ploughed in with whatever news outlet they read it on.
The clearance for AC8646 to land on runway 4 is given in a sequence starting at 4:58. "Vehicle needs to cross the runway" at 6:43. Truck 1 and company asks for clearance to cross 4 at 6:53. Clearance is granted at 7:00. Then ATC asks both a Frontier and Truck 1 to stop, voice is hurried and it's confusing.
If only we could diff the BBC article (it currently says it was posted 21 mins ago which is younger than your comment…). It’s changed multiple times now without any kind of changelog or acknowledgement.
> Video footage on social media showed the aircraft, which is operated by Air Canada's regional partner Jazz aviation, coming to a rest with its nose upturned.
This just isn’t true. There’s no video of the plane coming to a rest with its nose upturned (which implies motion). The upturned nose happened only after passengers deplaned and the balance shifted.
> It had slowed to about 24mph when it collided with a vehicle from the Port Authority of New York and New Jersey, which runs the airport.
This is the next part that will change. Just because some of the last broadcast data said 24mph doesn’t mean that’s the speed it was when it collided with the truck. The truck is on its side and those passengers are in hospital. The pilots are dead. The plane sustained enough structural damage to have the entire nose collapse. If the sentence is based on that broadcast data, SAY THAT instead of printing it as fact.
And with all the quotes from social media posts from key groups, link to them instead of just vaguely quoting.
EDIT:
As expected, they got rid of the above paragraph claiming the speed. It now says:
“The plane was arriving from Montreal and had landed, before colliding with the vehicle from the Port Authority of New York and New Jersey, which runs the airport.”
Any of us can help log the changes by submitting revisions of the article to web.archive.org
With a fast-changing news story where vague/incomplete/conflicting details emerge in the first few hours it's not unreasonable for the first few revisions to be like that, and eventually gets fixed hours or a day later.
I think that’s what’s critical here. Post details and their sources to show that they are in flux. Don't write them as fact and then make secret edits.
Because some of them still have standards. They will correct themselves if something was wrong.
Everyone can write a comment on Reddit / make a podcast / video / whatever claiming whatever they want. Unless you already know and trust them (which requires you to be able to cross-check their information), it's potentially as useful as a random LLM hallucination. Could be brilliantly spot on, or could be completely nonsense. No way of knowing unless you already know enough. (Because even cross-checking won't necessarily save you, if you cross-check multiple bullshit sources).
Media with standards (like the BBC, Guardian, Liberation, etc.) will do their best to report truthfully (even if sometimes with some bias), and will fix their mistakes if they're caught later on or the story evolves. Independent media checking organisations have shown time and time again that there is trustworthy media, you just need to know which it is, and always take a pinch of salt. It's wild to me that people will just dismiss rags such as Fox News and relatively quality media like Guardian in the same breath.
Introduce a foreign object onto the runway and it will inevitably collide with an aircraft. The fire trucks aren't part of the airport traffic management system, their sudden presence is bound to lead to problems eventually.
It wouldn't surprise me in the slightest if the truck has a single radio (airplanes always have two) and was constantly switching between ATC and fire house frequencies. The probably never heard the "stop, stop, stop stop.."
It would also not surprise me if airports previously had dedicated fire services, which have since been outsourced for cost reasons.
According to this article, the air traffic controller gave the fire truck permission to cross the runway. So, it seems like they are part of the air traffic management system?
In 2026, with how much money their is in aviation, it seems wild to not have digitized this ages ago. The runway should be essentially 'locked' when in use, if they don't want screens in every ground vehicle that may cross a runway, at least display it at runway entrances.
That ATC still takes place over radio just seems insane at this point. And there's pretty much no way to make ATC's job not stressful, its inherently stressful. Taking out how much of their job is held in the current operators mind versus being 'committed' seems like low hanging fruit 30 years ago.
The whole system's just begging for human error to occur. There's 1700+ runway incursions a year in the US alone, each one should be investigated as if an accident occurred and fixes proposed. Like when an accident occurs.
While modernizing ATC in the US may be overdue, the real issue here is that ATC in the US has been understaffed, underpaid, and overworked for a while now.
My father works ATC and his schedule has him working overtime, 6 shifts a week, including overnight shifts, meaning that there is literally not a day of the week where he doesn't spend at least some time in the tower.
If that's the reality for even half of the controllers, it's no surprise that we've been seeing more and more traffic accidents lately.
Seems like everyone, everywhere is overworked, underpaid, and under supported. How much longer can we frogs survive the boiling?
The point of the frogs boiling metaphor is the frogs in fact do not survive.
In reality when these experiments were conducted the frog simply jumped out as soon as the temperature started to raise, frogs will not sit there in slowly boiling water and just die without trying to escape way before the water becomes dangerous.
Well, it works with humans just fine.
We need to combine the crabs in the bucket with the frogs in the water and I think we'll have the right metaphor.
As long as we're desperate for a job and we need to finance our lifestyle to impress the Johnsons.
It's not even to impress anyone, we need to keep roofs over our heads and food in our family's bellies
Not everyone. If you were friends with Epstein you got insider information and a victim to abuse.
No that is not the issue. Runway incursions have always been a problem and many deaths have occurred.
There have been many attempts to change phraseology, teach pilots and controllers to always readback runways, etc. but nothing that actually prevents the issue from occurring entirely via automation.
Why do so many jobs have this failure mode? Thinking about this should illuminate for you that funding is not the whole story.
Inadequate funding seems like the common factor across the vast majority of jobs with these failure modes.
Okay, so then what is? Most jobs have this failure mode because there's a tendency to strip funding until disaster happens, even when it was clearly foreseeable.
Well, there was the time Ronald Reagan fired all the ATC workers because they were trying to unionize.
They were already in a union (PATCO) and they were striking illegally which lead to their decertification.
What's impressive is that if you look at the issues PATCO struck over, it was basically identical to the problems ATC faces today. The problem being that everything has only gotten a lot worse for ATC controllers.
The union pretty loudly and early on pointed out major problems with that job and the response of ignoring them for 4 decades is what's driven us to the current situation.
Technically accurate.
A union that isn't allowed to legally strike when needed isn't a useful union though. The state that ATC has been in for the decades after that suggests to me that they were correct to strike.
Can’t this whole thing being automated and let only special/unexpected situations being handled by humans ?
Nowhere has automated ATC because errors look like this.
That's like the argument about how we'll never (or should never) have self driving cars.
Clearly human-run ATC results in situations like this, so the idea that automated ATC could result in a runway collision and should therefore never be implemented is bad.
Imagine it were 90% automated. Now imagine there's a 3 hour outage of the automated system.
You're left with a bunch of planes in the sky that can't stay there forever, and not enough humans on the ground to manually land them.
Now image the outage is also happening at all airports nearby, preventing planes from diverting.
How do you get the planes out of the sky? Not enough humans to do it manually.
Now imagine the system comes back online. Does it know how to handle a crisis scenario where you have dozens of planes overhead, each about to run out of fuel? Hopefully someone thought of that edge case.
There's exceptions all the time. They turn back because a warning light came on. They saw a deer on the runway, a passenger got up to the bathroom. There's no way that could be automatic, plus they often need atc to look at their jet to see if it's damaged.
My suggestion is to restrict the use of smaller jets like crj and turboprops. I know airports like LaGuardia can't handle the big jets either, but they could reduce the slots and require a jet that holds, say, 150 people or more. This would result in fewer flights per day to some airports, but reduce overall congestion while still serving the same number of passengers.
Automating ATC is similar to automating flying in general. Even if it's possible to automate 99% of 99% of flights, including even takeoff and landing, commercial flights still have two pilots because if things start to go wrong there's just so many edge cases that you can't easily write automation to handle all of them. Same thing for ATC, except even worse. They still have control towers because controller eyeballs still work even if nothing else does, if ground radar fails, or if a vehicle doesn't have an ADS-B transponder, or if a crash eliminates the radios, etc. There's just so many edge cases that making automation be able to handle everything is extremely difficult
Air traffic (and ground traffic) control are not simple problems. La Guardia has 350k aircraft operations (takeoffs and landings) every year. 1000/day. Peak traffic is almost certainly more than 1 plane every minute. Runways are always in use and the idea that some simple software will solve all the safety problems is not grounded in reality.
This isn’t hypothetical, this system just exists in other countries. Digital systems can confirm flight instruction from ATC with zero radio communication.
Changing the delivery method doesn't do anything to solve the problem of a controller sending an instruction that creates a hazard.
I’m not saying we couldn’t move more into automation. What I’m saying is that doing so will not solve all of our air/ground control problems. We still have human pilots and humans driving vehicles on the ground. Switching from humans directing landings to machines might improve some things but will not solve for all (and probably not most) risks.
Literally the crash here was caused by a fire truck entering the runway.
The ATC told them to enter the runway because they were confused or distracted due t overwork.
No one here or anywhere is saying automation would solve or be able to handle everything that human operators handle, that's an argument you invented that no one is making.
People are saying automation could handle a significant portion of the routine things allowing humans to handle the more complex/finicky issues.
Even if automation could handle 10% of the most common situations it would be a huge boon. In reality its probably closer to 50%.
There's unfortunately an alertness problem WRT automated systems.
If the reason you have the human there is to handle the unusual cases, you run the real risk that they just aren't paying attention at critical moments when they need to pay attention.
It's pretty similar to the problem with L3 autonomous driving.
Probably the sweet spot is automation which makes clear the current set of instructions on the airport which also red flags when a dangerous scenario is created. I believe that already exists, but it's software that was last written in 1995 or so.
Regardless, before any sort of new automation could be deployed, we need slack for the ATC to be able to adopt a new system. That's the biggest pressing problem. We could create the perfect software for ATC, but if the current air traffic controllers are all working overtime and doing a job designed for 3 people rather than one, they simply won't have the time to explore and understand that new system. It'll get in the way rather than solve a problem. More money is part of the solution here, but we also need a revamped ATC training program which can help to fill the current hole.
> The ATC told them to enter the runway because they were confused or distracted due t overwork.
Very possibly. It will be interesting what comes from the investigation.
> No one here or anywhere is saying automation would solve or be able to handle everything that human operators handle, that's an argument you invented that no one is making.
I’m asking if it would have solved even the current situation. The truck presumably saw the red light, and was asking to cross. Would traffic control have said no if more had been automated and if so, what automation would fix this? Unless we are supposing the truck would be autonomously driven and refuse to proceed when planes are landing, in which case, maybe, though that’s not really ATC automation anymore.
an automated system that could check if a plane is about to land on a runway and show some kind of alert or red light is hardly a stretch of the imagination
> more than 1 plane every minute
Software routinely solves database coordination problems with millions of users per second.
I'm pretty sure the amount of data isn't the problem here. Maybe it's the number of corner cases? You would still want some human-in-the loop with quality UI for ATC.
There are plenty of stories of ATC helping to guide pilots back to the ground after an engine failure or after a student pilot had their instructor pass out on them or something like that.
Even if most of the work is routine, you definitely still want a human in the loop.
It's worth pointing out that plenty of pilots take off and land safely at uncontrolled airports. ATC is a throughput optimization; the finite amount of airspace can have more aircraft movements if the movements are centrally coordinated. It feels like we are nearing the breaking point of this optimization, however, and it's probably worth looking for something better (or saying no to scheduling more flights).
The FAA already does issue temporary ground stops for IFR flights when ATC capacity is saturated. This acts as a limit on airlines scheduling more flights, although the feedback loops are long and not always effective. The FAA NextGen system should improve this somewhat.

with extremely controlled conditions. There is no fog in database, nor fallible humans involved, What an ignorant response
In a digitized environment. We cannot yet simulate the real world.
True. But to avoid 1 minute unavailability per year requires 99.9999 % availability
Like any scale system, degrade the experience. Use radio if the more advanced systems are unavailable?
Yup, by having backup runways.
A third runway for Heathrow was formally proposed in 2007 and is projected for completion in 2040. This is an airport so overburdened people are buying and trading slots.
This isn't a Kubernetes cluster where you can add VMs in 30 seconds.
https://en.wikipedia.org/wiki/Expansion_of_Heathrow_Airport
And no fire trucks crossing the runways.
....they need to get to fucking fire
....if they go around kilometer of the runway the fire will turn into bigger fire
Two trucks
>> Software routinely solves database coordination problems with millions of users per second.
A naive view that confuses the map with the territory.
While in a database state you write a row and reality updates atomically....for aircraft they exist in a physical world where your model lives with lag, noise, and lossy sensors, and that world keeps moving whether your software is watching or not. Failed database transactions roll back, a landing clearance issued against stale state does not. The hard problem in ATC is not coordination logic but physical objects with momentum, human agency, and failure modes that do not respect your consistency model.
No one said it was simple. You're tilting at windmills.
Literally called it “low hanging fruit”.
But context is important. "Low-hanging fruit" doesn't mean the solution is "easy" in a vacuum, it just means this specific aspect is the easiest and/or most obvious place to start attacking a problem.
Or to stick with the language of the analogy, every fruit tree has some fruit that is lower than the others. That doesn't mean all "low-hanging fruit" is within arm's reach of the ground, some fruit just doesn't require as big of a ladder as other fruit.
This comment isn't a judgment of this specific case. I don't know enough about ATC to have any confidence in my opinion on the viability of replacing humans with software.
That goal post moved so fast it made a whooshing noise as it passed
I think you're mistaken. That whooshing sound must have been my comment flying over your head.
That was my first comment in this thread, so there was no established goal to change. My sole goal was to clarify the meaning of an idiom that the comment I was replying to was misstating.
I even included a disclaimer that "This comment isn't a judgment of this specific case", so I don't know how you could have received it as such.
Hehehehe, grounded.
You can't just throw software at this. It's a complex system that involves way more than just an airplane and someone in a tower. Systems engineering, human factors, and safety management systems are the relevant disciplines if you'd like to start reading up. In addition there are decades of research on the dynamics between human operators and automation, and the answer is never as simple as "just add more automation." Increased reliance on automation can paradoxically decrease safety.
CPDLC is already being deployed domestically. It's currently available to all operators in en route segments.
All runway incursions at towered airports are reported, classified according to risk, and investigated.
On the flipside, look at the success of TCAS. It doesn't have a perfect operational history. It hasn't completely eliminated midairs, either. But it took a relatively rare event and further reduced the frequency by about a factor of 5.
I wouldn't be so quick to rule out that there's some kind of relatively easy technological double check that could greatly reduce incidents. The fact that we've not gotten there despite years of effort to reduce runway incursions doesn't mean that it's not possible.
TCAS is fantastic - absolutely stellar example of effective automation.
But calling a replacement of major ATC functions with software a "simple fix" is a perfect illustration of why this is a bad idea. Nothing about human-rated safety-critical software is simple, and coming at it with the attitude that it is? In my view, as an experienced pilot, flight instructor, spacecraft operator, and software engineer, that thinking is utterly disqualifying.
Besides, there already are a lot of "simple" fixes in place for this problem, e.g. RWSL, which didn't prevent this accident.
I don't know. At some point, you need to do all the systems engineering. But "why not just ......" is a perfectly reasonable place to start looking at a problem and sometimes the answers really are that simple.
> Besides, there already are a lot of "simple" fixes in place for this problem, e.g. RWSL
It'll be interesting to hear why RWSL didn't help, as it is supposedly deployed at LGA.
You could put a TCAS on every ground vehicle. It's not rocket science.
Yes, I know it probably costs $300k, surely today you can have a $10k ground version.
You could also show every plane on a screen inside the vehicle and have some loud alarms if they are on a collision path.
You could even just display FlightRadar24, still better than nothing.
You would still get permission for the tower, this would not be an allow system, just a deny system.
> You can't just throw software at this
Ok, let's not try improving systems, how's that working out?
> The runway should be essentially 'locked' when in use, if they don't want screens in every ground vehicle that may cross a runway, at least display it at runway entrances.
It does, the Runway Status Lights System uses radar to identify when the runway is in use and shows a solid bright red bar at every entrance to the runway. I'm curious what the NTSB has to say about it for this incident. From the charts LGA does have RWSLs. I didn't check NOTAM to see if they were out of service though.
Emergency vehicles almost always can override/ignore warning devices (think firetrucks running red lights) which can cause "fun" for some value of "death/dismemberment/vehicle loss".
https://www.youtube.com/watch?v=A0Xf7aU5Udo
Airport emergency services are presumably trained in this, but since a plane cannot stop easily (or not at all on takeoff after V1), I seem to remember the general rule is that even emergency vehicles with lights and sirens on give way to planes, and don't enter runways without permission from the tower.
In the audio released by the BBC, the fire truck DID get permission from the tower to cross something, I can't tell if it was the runway in question. However, to cross the red runway lights if lit, you normally need that spelled out too something like "truck one, cross four delta, cross red lights". This did not happen on the BBC audio, which could mean one of many things.
They got clearance, which was overruled by a STOOOP!
The guy was alone operating 2 frequencies, had an emergency of another aircraft going on… is not so easy as many commenters from the armchair are insinuating
They got clearance and then obviously didn't bother to look outside, which is a dereliction of the basic responsibility of operating any vehicle on an airport surface. Clear left, clear right, then cross the hold short line.
(See my other comment below if you're tempted to say something about visibility.)
They could not see, because delta crosses in diagonal to the runway, such that the plane comes from behind (and the right side) so the driver has no chance to see. The truck was moving fast which is ok, because you want to clear the runway as fast as possible.
From where I'm sitting, it's not really "the fault" of ATC (even though it is) simply because I'm not trusting enough of ATC even when they're on "my side".
When cleared across a runway I'm still going to be looking in all directions, and proceed as fast as I can. I also look both ways at railway crossings even if the guards are up and silent.
I wonder if visibility was good enough that looking both ways before crossing the runway would have prevented this.
No. it wasn't. Delta crosses 04 in diagonal, so basically they should have taken the head out of the window and look behind. They had the clearance, so they just tried to cross. The problem is for some reason they did not hear the "Truck 1 stop" call.
That'll be one of the things the NTSB investigates.
I also wonder if you're down to a "one controller" scenario if it would be better for there to be once frequency, not a ground/air split.
All vehicles can override/ignore warning devices. Doesn't make it right. Emergency vehicles should not override/ignore train or plane crossings. Trains and Planes don't care about flashing lights. Crossing an active runway requires clearance for safety.
In this case, from the available information, the drivers of the fire truck thought they were cleared, and proceeded to cross while a plane was cleared to land. I'm not familiar with ATC ground radio to know if they were actually cleared or not, but it seems clear that that the drivers thought they were cleared.
Investigation reports will give us more details.
How would you exactly "digitize"? While that sounds like a nice idea in theory it's the same as "digitizing" road traffic.
In the end the air traffic system is a highly complex but also a highly reliable system, especially when you compare accident rates.
I am sure the working conditions of ATC staff might be improved - but being both a pilot and a programmer, I know that there is no easy digitalization magic wand for aviation.
The Runway Status Light system already does this via automated monitoring of traffic from multiple systems: https://www.faa.gov/air_traffic/technology/rwsl
I'm sure the NTSB report will cover why this didn't stop the accident. Presumably either the system wasn't working as-expected, or the fire truck proceeded despite the warning lights since they had clearance from the controller.
The system is only advisory at present, so if the truck did see a warning light and proceeded anyway, they were technically permitted to do so.
>In the end the air traffic system is a highly complex but also a highly reliable system, especially when you compare accident rates.
1700 incursions a year, and other articles mentioning multiple near misses a week at a single airport [1]. It is safe in practice, likely largely due to the pilots here also being heavily trained and looking for mistakes, but it seems a lot like rolling the dice for a bad day.
>I am sure the working conditions of ATC staff might be improved - but being both a pilot and a programmer, I know that there is no easy digitalization magic wand for aviation.
I didn't say it'd be free. Just hard to believe radio voice communication is the best way to go.

> While that sounds like a nice idea in theory it's the same as "digitizing" road traffic.
Traffic lights instead of mad max intersections are better.
Then there's subway Automatic Train Control.
I don't know that Air Traffic Control staff don't have computer systems for establishing which plane owns what airspace. They at least did do it manually already following specific processes, so it can be at least augmented and a computer can check for conflicts automatically (if it isn't already). And, sure, ATC could still use radio, but there could be a digital standard for ensuring everybody has access to all local airspace data. Or maybe that wouldn't help.
Your ground vehicle wanting to cross a runway could have the driver punch "cross runway 5" button (cross-referenced with GPS) and try to grab an immediate 30 second mutex on it. The computer can check that the runway is not allocated in that time (i.e. it could be allocated 2 minutes in the future, and that would be fine).
But, as pointed out elsewhere, obviously some of this is already present: stop lights are supposed to be present at this intersection.
The problem is knowing before today how to handle the case where a ground vehicle isn't across the runway in those 30 seconds.
It's already digitized, he's clueless. The ATC knows where vehicle was and where the plane is going, it looks as simple case of mistake or maybe not watertight enough procedures
I'm sure they've started all of this a few times over the past decade. The problem is in the US if you can't start and finish a project like that in less than 2 years then it's effectively dead in the water. The last time we "modernized" ATC was closer to the 90's than today, when there was still some general political will to make our government agencies modern instead of tearing them to pieces.
The FAA NextGen program has been running for literally decades. They have made some progress but there's a lot of work left to be done.
https://www.faa.gov/nextgen
Ha. My first job in '89 was working for an FFRDC reviewing IBM's Jovial code that was going to "revolutionize ATC" by modernizing everything.
I'm gonna guess that code never went into production. The problem seems easy until you start looking under the hood.
There are systems for it, just not really integrated into emergencies and ground vehicles. Mistakes also happen even if all info required to avoid is present
The BBB allocated $12B for ATC modernization. https://www.faa.gov/new-atcs
Money isn't the only reason it's so old. The coordination problems are huge. https://www.theregister.com/2024/09/24/us_air_traffic_contro...
> That ATC still takes place over radio just seems insane at this point.
There is digital comms with ATC without voice:
* https://en.wikipedia.org/wiki/Controller–pilot_data_link_com...
* https://www.faa.gov/air_traffic/technology/DataComm
But in the highly dynamic environment of final approach, landing, and taxiing, I doubt it would be practical. Unless we want to try autonomous 'driving' on taxiways and runways?
> There's 1700+ runway incursions a year in the US alone, each one should be investigated as if an accident occurred and fixes proposed. Like when an accident occurs.
How many runways crossings are there in a year? How much is "1700+" a percentage of that total?
A "runway incursion" is a very broad term that includes everything from this accident to a single engine Cessna moving past the hold short line prematurely at a quiet airport.
FAA defines it as "Any occurrence at an aerodrome involving the incorrect presence of an aircraft, vehicle or person on the protected area of a surface designated for the landing and take off of aircraft." [0]
Many runway incursions run no risk of any accident, but are still flagged as issues, investigated, and punished if appropriate.
[0] https://www.faa.gov/airports/runway_safety/resources/runway_...
The point is that it doesn't matter what percentage of the total they are, it's that 1 is too high without adequate explanation (the Gimli Glider caused vehicles to be guilty of a runway incursion by turning an abandoned runway into an active one, for example).
And the cost of investigating 1,700 should be within the budget.
Of course it matters. All of these entities have limited budgets and personnel and almost unlimited ways they could apply those resources. They have to choose what to chase and they do that by deciding how big of a problem it is.
If 1,700 is a huge percentage of runway uses (obviously it isn't but grant it, say at a single airport), then it's mandatory it be investigated because it's so huge.
If 1,700 is a minuscule fraction of all runway uses (as it likely is) then investigating it should be a proportionally minuscule amount of the budget.
There are five categories of incursion, with the top one being where a collision occurs:
* https://en.wikipedia.org/wiki/Runway_incursion#Definition
* https://www.faa.gov/airports/runway_safety/resources/runway_...
All incursions (in the US) are tracked:
* https://www.faa.gov/airports/runway_safety/statistics
Given there are ~45,000 flights per days in the US (and so aircraft and vehicles would move hither and fro around an airport for each flight), 1700 feels like a small number.
Exactly - it's a small number and should be investigated, because if we reduce the number of all incursions, we reduce the number of collisions (and fatalities).
They are classified as operation/ATC error, pilot error, and vehicle/pedestrian error.
Human can misspeak or mishear instructions, but if they were communicated and understood correctly (a read back was correct), but the pilot had a 'brain fart' and went forward instead of stopping, how do we eliminate brain farts?
That's a big part of the story of aviation; the way things are communicated has changed because of brain farts, the way things are lined up, etc.
See 5-2-5 for an example:
https://www.faa.gov/air_traffic/publications/atpubs/aim_html...
NOTE- Previous reviews of air traffic events, involving LUAW instructions, revealed that a significant number of pilots read back LUAW instructions correctly and departed without a takeoff clearance. LUAW instructions are not to be confused with a departure clearance; the outcome could be catastrophic, especially during intersecting runway operations.
The older term was "hold short runway X" and that was too close to "hold runway X" - the first meant do NOT enter the runway, the second meant enter and line up but do NOT takeoff.
The old version of “line up and wait” was “taxi into position and hold”. “Hold short of runway” is still in use but means something different.
You can't know how big of a problem it is without an investigation. Frequently, the initial "obvious" cause of a collision or incursion turns out to be a multi-layered set of failures. Tightening up procedures or recognizing a previously overlooked defect in the systems makes us all safer and should be prioritized.
We talk about Vision Zero for streets. Vision Zero is actually achievable in aviation.
My very fuzzy back of the envelope says easily 10s of thousands per day.
I would not trust my life to a government software project (See Phoenix Payroll for a typical case)
You seem to be giving too much credit to the singleton design pattern. We know exactly how well that works on a modern, multi-tasking, preemptible operating system (hint: not well at all).
> That ATC still takes place over radio just seems insane at this point.
Voice communication is insane? I suspect you are ignorant of what it is like to actually fly a large aircraft into a busy airport. Fault-tolerant and highly available hardware must facilitate low-latency, single-threaded communication with high semantic density in order to achieve multi-dimensional consensus in a safety-critical, heterogeneous, adversarial environment.
There is some interesting research that captures this sentiment and shows how complex a solution might need to be (replace "faulty agent" with "human error"): https://www.sciencedirect.com/science/article/abs/pii/S00051...
Listening to some recent close call ATC tapes, yes, it seems absolutely insane to manage current traffic levels with the existing number of controllers over voice.
I don't doubt that it's a very safe system with enough slack allowing for intentional redundancy. But as it is, some of these controllers seem to be limited by their ability to pronounce instructions, leaving absolutely no margin for error and presumably very little room for conscious thought.
Voice communication has the advantage is that it can be used without taking off hands and attention off controls. Digital solution would require using device.
Voice communication can still be used for anything out of the ordinary despite automating the common case.
Almost all voice transmissions are routine instructions/clearances from ground to air, with the pilots reading them back to reduce the chance of errors. In fact, this already exists and is in wide use in (at least) the US, EU, and in transoceanic airspace.
Of course, now you have two systems that can fail, and reducing reliance on the older one can easily cause automation complacency (which is a well-researched source of errors) and require more frequent refresher courses if the skill is not practiced on a continuos basis.
I suspect that that these are the reasons it's not commonly used for approach and tower operations: There's a lot more spontaneous and/or nonstandard stuff happening in those flight phases, and as you say you don't want a pilot's eyes on a tiny screen/keyboard instead of on their instruments or out the window.

ATC recording on https://www.liveatc.net/recordings.php Fire truck was cleared to cross and then told to stop. I'm not sure if they were the only controller working at the time, they continued working after the incident which seems unusual; my understanding is normally they'd be relieved by another controller.
They were indeed the only controller, working both ground and tower frequencies.
Which, as a non informed person but someone who needs to travel by plane, sounds absolutely insane. Was it always possible to staff that with a single person or is that a result of understaffing?
As an informed person (PPL flying single engine into smallish towered airports all the time), it is absolutely insane for an airport the size of LGA. Occasionally, you will encounter one guy doing tower and ground at very small class D airports or during not-so-busy shifts.
To play devil's advocate, ASEL into small deltas is significantly different than receiving full-stop IFRs late at night.
This small mistake (and it is initially small, just catastrophic) is a system breakdown, not necessarily a staffing breakdown. Though staffing is definitely a wider issue in the NAS.
Edit to add: looking at this incident closer it appears LGA was busy enough to make a single tower/ground controller an obviously bad plan. Still, systemically, there's enough low hanging fruit here, like ADSb in for the airport trucks or hold short line guard lights. I hope the takeaway isn't just "don't have controllers make mistakes".
Yea, if you listen to the ATC audio, you can hear that in addition to the normal high workload of handling both ground and tower, this guy had an emergency aircraft on a taxiway to deal with, too. A lot of holes in the swiss cheese lined up, but one of them clearly is ATC workload.
Speaking very generally, it's not unusual at all. Tower and ground are combined all the time - at smaller airports.
Should they be combined at LGA when both (crossing) runways are in use, and there's an incident on the field? (The fire trucks were on their way to investigate a smell on the flight deck of another airplane that had to abort takeoff twice.)
I'd say hell no.
I fly out of a small-to-medium-sized airport in Canada and I've never seen it happen there. The idea of one person being responsible for both tower and ground in the busiest airspace in the US is absolute insanity.
Agreed, but isn't O'Hare the busiest airport in the US?
Edit:- It's Atlanta.
Busiest airspace and busiest airport are two different things, technically.
The airspace that combines JFK, LaGuardia, and Newark, is the busiest airspace in the US.
It's a crazy airspace. Add to that Teterboro, 12 miles from NYC and Republic ~20 miles from NYC, along with all the heliports on the Hudson.
I don't envy anyone having to work in that airspace in any capacity.
That seems unusual to me. It’s common at smaller airports, but for a big one like LaGuardia I’d think tower and ground would be two different controllers, even lateish at night like this was. I know there has been a staffing problem for controllers in the NY area for some time.
It's not unusual for airports to reduce staff at night, and the incident occurred at 23:36 local time. Even at a very large airport in a very busy traffic area, one controller can probably handle normal operations at this hour.
The obvious problem is what happens when operations become abnormal. ATC shouldn't be staffed for normal operations, because then abnormal operations lead to catastrophe. Welcome to last night: the weather is bad, which causes a plane to abort two takeoffs, which causes that plane to need emergency services. This increases the controller's workload beyond his capacity, so he accidentally clears the emergency vehicle to cross in front of a landing airplane, and they can't see the airplane because the weather is bad, so they follow the instruction and promptly get hit with an airplane.
When some bad weather can be the difference between "this is fine, one controller can handle it" and two dead pilots, you need to be staffed for bad weather.
Reddit aviation groups are full of professional pilots, saying how terrified they of flying into La Guardia or JFK, recounting close calls, with one saying how he avoided those two for 10 years...
It IS insane. Specially for LGA
It's absolutely understaffing.
But think of the money they saved by not having to pay another air traffic controller! A controller's yearly salary is the cost of about 10 seconds of the Iran war, based on the recently-reported figure of $11.3B for six days.
I don't think it's money. I think it's requirements and training pipeline restraints. The system is predicated on being able to throw bodies at the problem, but there is a distinct lack of qualified individuals to back that up. Personally, I didn't realize ATC as a possible career path until I was 36-- imagine my surprise when I found that I had already aged out.
Who would want to work that job once they find out what the day-to-day is like? I had an intern who looked at that out of the Air Force but he found out what you get paid and what the expectations are for the job and he figured he'd try his luck on something easier and better-paying like life-preserving medical devices. On a related note, why do you think nobody who you'd actually want teaching public school actually teaches public school in the US?
It’s not a money thing. It’s a shortage of people who are mentally able to do the job mixed with terrible hours and early forced retirements. ATC school has a failure rate of over 50 percent.
It's partially a money thing. ATC is under-compensated. They'd get more - and more talented - people interested if the money made up for the stress, hours, and early forced retirement.
Why not both? If it paid better then more people would apply to ATC school.
ATC positions already have a very low chance of even getting a spot in ATC school. There are tons of applicants for every opening.
> I'm not sure if they were the only controller working at the time, they continued working after the incident which seems unusual; my understanding is normally they'd be relieved by another controller
I remember late last year, couple of months ago, US ATC controllers were without pay but forced to work anyways (similar to TSA I suppose, although I don't think they were forced, but volunteered to work without salary), is that still the situation? Couldn't find any updates about that the situation been resolved, nor any updates that it's ongoing, if so though it feels like it'd be related to the amount of available controllers.
ATCs weren't exactly forced to work: they aren't slaves and are free to quit any time. But if they didn't show up for assigned shifts even though they weren't getting paid then they were subject to disciplinary action including termination. Some of them called in sick, or took on temporary second jobs to bring in some cash (obviously a bad thing from a fatigue management standpoint). After the government shutdown they were paid in arrears for all of the hours they worked. It's crazy that Congress plays political games with essential services like ATC.
The US has had trouble keeping enough controllers. It's a skilled but extremely stressful job, and so retention would always be difficult but the US also works hard to make it suck more than it should, and of course the over-work from not having enough people makes that even worse.
But no, AIUI only things that were somehow deemed part of "Homeland Security" are frozen, the TSA are part of Homeland Security but the ATC are under the FAA. So this particular partial government funding lapse wasn't causal, at least directly.
Specifically, Reagan made a point to cut our nose to spite our face just to not pay ATC workers more money. For political and Ideological reasons.
So why the fuck would any talented individual choose to go work for the "Get an example made out of you" department, on top of the horrific stress of the actual job!?
The idea of a union that "isn't allowed" to strike is a joke. Next will be a union that has a max membership of 1!
The budget was signed Feb 3 this year to fund most of the govt (excepting DHS) through September 2026. ATC were not paid from Sept 30, 2025 until Feb 4, 2026. They receive back pay. They are also supposed to get a raise and funds set aside to hire 2500 more ATC but that is currently held up in the DHS funding fight.
It's a mess.
Utterly unqualified to suggest any causes (wait for the NTSB report on that), but couple compounding factors I've read elsewhere to begin to understand the situation and context:
- Another plane was out of position, grabbing some attention of the controller
- Stop communication was ambiguous about whether talking to previous plane or firetruck
- The colliding plane didn't have "explicit" landing clearance, but a "follow previous plane and land the same way unless told otherwise" implicit landing clearance. In Europe, planes need an explicit landing clearance, the act of granting it may have brought attention to the runway contention. US implicit system (arguably) is a bit more efficient, debate will now be is it worth it (pilots are now required to read back instructions because of past blood... will this result in same thing?)
- This was around midnight and apparently a little foggy, making visual contacts harder
Remember folks, disasters like this are rarely caused by a single factor. NTSB reports are excellent post-mortems that look at all contributing factors and analyze how they compounded into failure. Be human here.
In the USA at controlled airports, aircraft also need explicit landing clearance.
"Jazz 646, number 2, cleared to land 4."
https://youtu.be/Pbm-QJAAzNY?si=h3VEuVNLMf9Z8D1c&t=126
> Stop communication was ambiguous about whether talking to previous plane or firetruck
"stop stop stop, truck 1 stop stop stop" I mean maybe it was ambiguous for half a second but he pretty quickly said "truck 1 stop". I guess we'll have to wait for the sync up to see if it was too late to stop by then
They did have a very explicit clearance.
The controller said “truck 1 stop” that is not ambiguous.
I’m always staggered by how stressed and tbh (not necessarily their fault given the circumstances) unprofessional US ATCs sound.
Sharp contrast with Europeans
In Europe is illegal to capture and publish ATC. I don't understand why. Anyway I do not know what are you comparing.
From pilot friends, in best case I would say a big “depends” in some countries are very unprofessional, in others very professional (anyway total unfair generalization). There were already accidents because of that, for example because the twr communicated with locals in non english, so not everybody was at the same page.
Emergency vehicles were en route to another emergency in progress on the other runway. Sadly it sounds like a fire truck was cleared to cross the active runway moments before the CRJ landed. By the time the controller realized that mistake it was too late.
I'm very, very curious about whether the ARFF crew visually cleared the runway and final before crossing the hold short line. It's standard procedure for flight crew to do this, specifically to mitigate the risk of ATC errors.
Reports are there were fog and rain at La Guardia at the time of the incident. They were on a short final, and it’s entirely possible they were not visible to the fire truck’s crew.
I have over 1,000 hours as PIC in the NY area alone, in all seasons and all weather, and I was in the region last night, awake when the accident happened. LGA was reporting 4SM -RA BR FEW045 BKN090 OVC110 at the time of the accident. The weather wasn't anywhere close to what I'd call "bad" here. Sprinkles and some high clouds.
I can almost guarantee you the airplane was visible from taxiway D.
At night with multiple runways it can be very hard to see a plane on final.
Still, I'm always hesitant to cross an active runway.
Yes ARFF should still look before crossing, but the weather wasn’t great with limited visibility and thus even if they looked it’s possible they didn’t see anything.
I mean, isn't it obvious that they didn't?
It’s obvious that either they didn’t, or they did but they didn’t see the plane. We don’t know which.
Do we know what the other emergency was? All the reporting I've seen has been very vague on this.
United aircraft did a high speed abort (80+ knots) and afterwards, fumes from hot brakes were entering the back of the cabin. (Not uncommon.)
Source: Mentour Pilot. https://www.youtube.com/live/Bb4CcoK0KLM
Unrelated United aborted takeoff, as well as reported some odors in the cabin from the flight attendants.
Was curious if ground vehicles at airports also use transponders to communicate position to the radio tower, and it turns out the FAA put out a report last year on potential solutions to avoid this exact situation:
https://www.faa.gov/airports/airport_safety/certalerts/part_...
Many airports have ADS-B transponders in their ground vehicles. You can see them on flightradar or adsbexchange.
> Was curious if ground vehicles at airports also use transponders to communicate position […]
They do at CYYZ (Toronto Pearson):
* https://www.flightradar24.com/43.68,-79.63/13 (zoomed in)
* https://www.flightradar24.com/airport/yyz
Also at CYUL (Montreal Trudeau) and CYVR (Vancouver International).
Ground vehicles with transponders: https://adsb.exposed/?dataset=Planes&zoom=7&lat=42.1262&lng=...
Or just do like the rest of the world. No anticipated clearences to land, you only ever get a clerance when the runway is empty and yours.
I think this is a good idea.
The only negative I can think of is that it will generally involve accepting and responding to clearances on short final. I think adding more tasks to that critical stage of flight probably increases danger a little. Especially for low time student pilots like myself. That's particularly relevant in the U.S. because we have a higher percentage of student and private pilots than most of the world.
Overall, though, I'm fully convinced this would be safer.
Even without anticipated clearance to land you have to define what "the runway is empty and yours" means.
Yeah that gut wrenched ATC had to stay on point and ensure the next plane to land did a go around. Scary stuff.
Us lot have more people doing SRE ensuring p99 10ms for something frankly way less important. It is a nuts world.
LaGuardia has that system, it still failed to prevent this
Transponder doesn't alter the laws of physics for the landing plane you just cut off. I guess it gives ATC a ~5sec jump on telling some other flight to go around.
I'd bet a lot of money that however the system is implemented the police and fire get special treatment when it comes to process (i.e. asking permission before they go somewhere planes might be) and that is part of what lead to this.
> I'd bet a lot of money that however the system is implemented the police and fire get special treatment when it comes to process (i.e. asking permission before they go somewhere planes might be) and that is part of what lead to this.
I highly doubt that any system would intentionally give ground vehicles of any kind special treatment on an active runway.
The trajectory of the plane is obvious enough that it should be able to predict where it will likely be in 30 seconds or a minute. You can't cheat physics, if it is going down in direction of runway, it is landing or at worst will do go-around, so the services should be alterted runway is no-go automatically

make a mistake, recognize it, and then have to continue on your job, knowing you likely just killed people, because if you don't others will die.
The weight of some jobs is immense, and our civilization relies upon workers to shoulder the burden everyday.
He asked the truck to stop multiple times. That's got to be so stressful and annoying - knowing you asked the truck to stop, but for whatever reason the command wasn't received.
We dont know the timing. He may have issued the stop command as the crash was occuring
And these guys are tremendously overworked because the government can’t get its shit together to hire enough people to staff at appropriate levels.
"Government"? Let's call it what it is. ITYM "Republicans".
The shortage of ATC staff dates back to the Clinton Administration. It’s just hard to attract people into a 5+ year training program for a very stressful job where you might get bounced near the end with no payout and no transferrable job skills.
No the shortage goes back to Regan when their justified strike was busted. It ended the PATCO “union” and was a negative turning point for labour unions in general.
I think you mean Reagan. He removed the union for the ATC not Clinton.
Honestly, you can generally just blame Reagan for about anything. A presidency about weaking labor, strengthening Iran, and ballooning the deficit is uh never going to leave good traces.
Reagan did the right thing in that case. Government employees should never have collective bargaining rights. Public employee unions are contrary to the interests of taxpayers.
Centralization of all power in the government is also contrary to the interests of the taxpayers.
Every time i see an anti-union article, its usually about unions that do good union things...
But noone ever complains about the police union. It's always the public goods people like ATC or teachers.
People complain about police unions all the time, it's just their complainants don't overlap much with the people who complain about private sector unions.
Over the course of the past year, I think we've seen more evidence that the federal workforce's collective bargaining rights aren't strong enough. Workers' employment contracts are being ignored, employees are being threatened, constructively terminated, all in an attempt to enact RIFs without following the law.
Things are happening to the federal workforce right now that aren't even legal in the private sector.
If contracts are violated then the impacted parties can seek redress through the courts. Government employee unions aren't needed for that.
You have to have your contract violated for a significant amount before you can notionally afford to hire a lawyer to fight it out. Below 5 figures it doesn't make much financial sense to do that for most people, so they just eat it instead. It's how a lot of "theft of wages" and other mistreatment happens so often. Lawyers don't take those cases for free, and court isn't free either. And you're not going to instantly appear at the top of the docket for something small like that especially if the government buries you in procedure. They can do that for years.
But sure, yeah you can seek redress through the courts.
Suing the federal government solo is an insurmountable task for most people -- even more so while they're being constructively terminated. Employee unions have been suing on their workers behalf over the past year, but the executive branch can drag out federal trials for a lot longer than people can stay without a job.
Does your comment also include the police union(s)?
Yes absolutely. They're a perfect example of the unique issues w/ collective bargaining for public services.
Yes, absolutely. No government employees should ever have collective bargaining rights. If they want better wages and working conditions then they can advocate for those through the political process, the same as any other citizen.
In your suggestion any other citizen has collective bargaining at their disposal, do they not?
Collective bargaining rights shouldn’t even be a separate thing. They’re just a natural consequence of the fact that free speech is protected and slavery is illegal. The idea of an illegal strike is bizarre.
This is a discussion with nearly unanimous agreement that poor ATC working conditions are causing Americans to die in preventable aviation accidents.
Maybe this is the one evidence-driven case where you can be open minded about the value of a public employee union?
Public employee unions are contrary to the interests of taxpayers
This is not obvious on its face, but also, paying taxes is not my only concern wrt the civil society in which I live.
Not just attract, it also has very high standards. And many people fail out.
Somehow Europe manages to do that well enough.
ATC/GTC seems like a really strong candidate for partial automation with recent advances in AI. Obviously we'd still want some expert humans in the loop for exceptional situations, but I have to imagine there's a way to significantly reduce the cognitive burden/stress for these folks.
Recent advances in AI aren't useful for routine operations in safety critical domains such as aviation because we don't know how to verify and test them. An LLM is effectively an unpredictable black box with unknown failure modes. There is opportunity for greater automation but probably based on classical deterministic programming.
In addition to this, LLMs are also simply too slow right now to deliver the results ATC would need.
Ridiculous to see people acting like LLMs are a silver bullet for every problem without putting any thought into what that would actually look like.
Yes. Reagan was a Republican.
No, I mean government. This has been a problem for a long time and there hasn't been any serious effort to improve the situation by anyone.
Yup, it's been a problem ever since Regan (a Republican) fired over 11,000 ATC employees. And by "anyone" ITYM "republicans" again, because Democrats have been trying for years.
See this article from 2017: https://www.govexec.com/oversight/2017/06/house-democrats-in...
How many years since Reagan have Democrats held both chambers of Congress and the White House? It’s a few. And yet we’re still here.
That's because all the Democrats are Republicans.
"”The truth of the matter is that my policies are so mainstream that if I had set the same policies that I had back in the 1980s, I would be considered a moderate Republican,” - Barack Obama [0]
[0] https://thehill.com/policy/finance/137156-obama-says-hed-be-...
This is not a statement of Republicans and Democrats being the same, but a statement of Republicans going off the deep end in during and after Reagan.
Obama was a very moderate Democrat for his time. If you go back in time a moderate Democrat and Republican were similar because the "center" was more reasonable. Now the "center" is just people that are ashamed that they vote Republican.
If we accept that, then "government" and "Republicans" would be pretty much synonymous, so my original point stands. (Not that I accept it, but even if I did.)
Another option: they shouldn't be government employees at all. It would be much better for them to work for the actual airports themselves and be certified by the government or a private testing organization instead.
LaGuardia, like many (most?) airports, is run by the government. This is a distinction without a difference, at least in this case.
Which government? State, Federal, City, or a Port Commission? There is in fact a significant distinction between the responsibilities and capabilities of each of these levels of government and you can't lump them all together. My home airport is operated by a port commission, which is government, but the port commission's task is to operate the ports.
>There is in fact a significant distinction between the responsibilities and capabilities of each of these levels of government and you can't lump them all together.
But all private businesses have the same responsibilities and capabilities and therefore can be lumped together as one entity? The asymmetry in how you're critiquing the way this is discussed ends up revealing your bias.
LaGuardia is not ran by a local government, not the Federal Government.
There’s a lot of ATC that isn’t specific to a single airport. And lots of airports are owned by a government anyway.
> our civilization relies upon workers to shoulder the burden everyday.
Our civilization? Nah. Just that one shithole country. Greatest country in the world and they schedule a single guy to work both tower and ground frequencies at a major airport, it's almost like they're asking for this shit to happen.
And before anyone mentions understaffing, this literally one of the plethora of problems that the rest of the world figured out while the U.S. continues to act special.
I'm curious about what kind of visualization does the ATC have at the disposal about the current occupancy of the individual tarmac segments? I'd assume if an airplane is approaching for landing on a specific runway, that runway should have been clearly marked as restricted for access until the plane would actually land and clear it?
In the US, airplanes can be cleared for landing while the runway is occupied (you can be number two, three, etc. for landing and still be cleared). It's different in other countries, where you can only be issued a landing clearance if the runway is clear or anticipated to be clear before you land (e.g. the plane before you is already exiting the runway).
Still, the runway could be reserved for landing aircrafts only, still preventing access to all other types of vehicles.
How are fire trucks supposed to respond to incidents involving airplanes, as it appears this case involves, if the runway is off limits to them?
The way it's supposed to work, the ground controller first verifies that there are no traffic conflicts before clearing vehicles to cross an active runway.
Which is exactly what failed here, so saying "it shouldn't fail by not failing" doesn't help terribly much.
Having grade-separate crossings for vehicles might, but that introduces new issues (plane skidding off runway could hit the incline and break up).
O’Hare has those but it’s not helpful for emergencies that happen on the runway itself.
How did it end up like that with the nose up: what is holding it up?
Gravity. The aircraft is heavier at the back, where the engines are. With the nose severely damaged/missing, the centre of gravity has shifted aft, so what’s left of the nose is sticking up in the air.
Google "weight and balance" if you'd like an in-depth answer.
Front fell off, people deplaned (while still horizontal) which shifted the balance backwards. It’s sitting on the rear bulkhead,
I guess there is more weight in the relatively small section of the front that came off than I expected
It's balance, you don't need a large difference in weight for it to tilt backwards.
I’d guess the front landing gear assembly is going to be fairly heavy, and appears to be missing. This model of plane also has its engines at the rear, not under the wing, which will move the balance to the back.
Oh yeah that definitely makes sense
Planes typically have their center of gravity just forward of the rear wheels. This makes it easier to rotate on takeoff.
The margins are thin enough that certain planes will sometimes have people in the back get off first, before the people on the front, to avoid tipping onto the tail like this.
According to other news sources, the pilots lost their lives here, too.
The entire cockpit, front toilet and galley area, and probably a front row seat have all been utterly destroyed. Unfortunately I'd be amazed if the death toll stays at two.
Are the increased number of air incidents since Dec 2024 reflective of anything real or is it more attention on something? Brigida v. USDOT comes to mind but doesn't seem relevant. I'm sure we could all construct a chain of "this thing happened that caused that which caused this" and so on, but I'm curious if someone has done the effort to see whether such a chain is defensible.
Also, did the pilots die in the collision or in some sort of aftermath? The cockpit looks absolutely smashed.
You can probably construct a realistic chain of failure that goes all the way back to political tomfoolery and bad air traffic control leadership/staffing decisions, but that makes the wrong people look bad, so they'll probably blame individuals further down the totem pole like the controller or pilot and call it a day.
Yet another blow to the confidence of flying in this country.
More accurately, the risk has increased by at least one order of magnitude, but the confidence of the public has largely stayed the same.
This comes to mind how during the Boeing news scandals, commenters would confidently argue "Flying is still ridiculously safe, statistically speaking", "these things happen every day, just underreported", and "you/people are irrational for not flying Boeing". It's a very curious argument to me. Is the ATC infrastructure issue analogous or not, etc.
You can view the actual data and control for your own recency bias one way or the other. I see data from 2005 - 2024 trivially accessible.
https://www.ntsb.gov/safety/Pages/research.aspx
Maybe US media, hardly an unbiased news source about US events, especially when hundreds of billions are flying around about incompetent massive employer and lobbyist.
Nowhere else in the world you would hear such statements. Boeings simply disappeared from Europe, those few that were here before. I am sure they are still used somewhere but I haven't flown any in past 7-8 years. Heck, I haven't seen any in South east Asia neither (but that may be due to luck).
I check this with all bookings, no way I am flying that piece of shit if I can anyhow avoid that, not alone and quadruple that with family.
> Boeings simply disappeared from Europe
That is just simply false. There are many boeings flying in europe. Just by randomly clicking around on flightradar24 I found multiple right now in the air.
It is strange. What is importa t is, are things getting better or getting worse? As they say, it’s not the fall that kills, bit the impact. Are we falling?
It should be noted that aircraft and all other vehicle and personel movements on an airport are controlled from the airtraffic control tower by air traffic controllers or directly by individual flaggers, as directed from the tower. Or at least thats the way it is supposed to work, and of course the operation at a place like LaGuardia is more complex, and will have specialists and multiple zones. What will put an extra edge on this is the whole ICE thing, and airport chaos pulling the roof down.
> What will put an extra edge on this is the whole ICE thing, and airport chaos pulling the roof down.
How would the ICE thing cause more ground traffic collisions. Are you thinking ATC controllers are illegal immigrants and they’re going to run away during their shift? I just don’t see a connection there…
Not the crash, but the aftermath. Passengers will be showing up for flights today, nervous with the crash on their minds, and many will then encounter untrained goons cosplaying as airport security.
I could see that, yeah.
This incident caused delays and cancellations that ripple throughout an already understaffed network of TSA checkpoints. ICE presence will make airport security somehow an even worse experience for brown people.
The comments in /r/aviation see to think it’s a one (tired) man show at night.

> "I visited them both in the hospital, as has the chairman, and they were able to speak and we're notifying their families," said Garcia.
Let's get the important parts out of the way first: We in charge have taken care of optics, with regard to our offices.
Oh, and we're going to contact families eventually.
That's a huge amount of damage even at 24mph. It's crazy how that could happen though. Will be interesting to see the full report.
The fire truck was flipped and moved to the side of the runway, this was not 24mph. 24mph is the final groundspeed recorded after the aircraft skidded off of the runway.
Per the ADSBx track the plane was at 101kts (115 mph / 185kph) just before crossing taxiway D, which would be where it hit the firetruck. It still had enough energy afterwards to reach taxiway E, 600ft away.
Okay that makes far more sense the article didn’t really make that clear to me.
The results seem on the high end but they check out at first glance.
A plane is basically a flimsy tube. A firetruck is a solid brick comparatively. The plane out weighs the fire truck by a lot and out speeds it by a lot. So yeah, destroying the whole front of the plane to punt the truck it sounds about right for a 25 on 5 or 35 on 10/15 type rear ending to me. Flipping doesn't really sound that unreasonable considering that the plane made contact with the top of the truck (just by virtue of comparative height) and contact may not have been straight on. Even if it left the pavement on it's wheels airport firefighters aren't exactly who I'd bet on (they're middle of the pack) to keep the truck on it's wheels if they got surprise kicked off the road especially if there's an embankment involved.
A CRJ 9000 is 70000 lbs empty, 84500 lbs MTOW.
An Oshkosh 1500 4x4 is 62000 lbs GVWR (wiki says kerb weight but it’s incorrect).
The plane was landing and the truck was heading to an intervention, so they were likely close to empty and to GVWR respectively.
And again, 25mph is the final ground speed, after the plane punted the truck and kept on going for 600ft.
>25mph is the final ground speed
Wouldn't final ground speed be zero?
Final ground speed reported.
Pause the video at 13 sec. That firetruck is awfully intact for something that allegedly got hit at high speed. Basically just a bunch of top side sheetmetal damage (concentrated to the rear, obviously). In any case it didn't even get sent hard enough to screw up the cab exterior. And on the flip side, if you keep cranking the speed up you start getting to where the plane starts looking too suspiciously intact. There's just not much room to work backwards from the apparent results and get a high difference in speed or get very high initial speeds (100 onto 75 or whatever). If the plane was going fast the truck had to be going fast too or there'd be more carnage. But if they were both going fast you'd expect more damage from the after the fact barrel roll and the plane and truck to be a little farther apart in distance.
Fire truck is filled to brim with gear and doesn't care all that much about weight, plane is the opposite of that, lightness is money, so it makes sense fire truck looks better after crash than plane
Where’s the video you’re referring to?
https://pbs.twimg.com/media/HEFF17eaYAA_sgq?format=jpg
I can’t tell what’s the truck and what’s the remains of the plane in this pic.
Another wider angle:
https://pbs.twimg.com/media/HEFDcS4bwAA8uu7?format=png&name=...
There’s no way this scene happens from a plane colliding with a truck at 24mph.
I'm talking about the headline video from TFA.
The back of a firetruck is not a working implement like a dump truck is nor is it sufficiently strong for mounting a crane or man bucket like utility bodies often are It's a bunch of sheetmetal boxes to hold stuff and cover stuff and there's a water tank back there somewhere. In the middle down low some pumps are buried. Basically don't think of it as being any more structural than a box truck body because it's not. All that stuff got shredded, obviously, since they're only really meant to bear their own weight and were subject to all the truck tossing forces here. Beyond that the truck is in pretty good shape. It's not uncommon for a good "off the highway and into the ditch" crash to rip tandems off, twist frames, etc. None of that has happened here. The plane is pretty rough, but that's expected. They are 100% tin cans. Ground equipment moving at idle speeds will absolutely shred them before the operator even feels resistance. A goose hit square on the leading edge of a small jet's wing will put a massive dent in (and apply red paint, lol).
24 sounds about right for a closing speed for plane onto truck. Whatever the baseline speed of the truck was cannot have been that high or the truck would be absolutely shredded from the barrel roll and as it stand the cab is barely pushed in.
The article dropped the speed claim.
The last recorded ground speed data of 24mph also shows a wildly different heading (going from 30deg ish to 170ish). So it probably happened after the collision and was part of its deceleration. As far as I know, the truck would have been crossing the runway so the effective speed perpendicular to the plane would be zero except for directional shear I guess.
> That's a huge amount of damage even at 24mph.
The speed was much higher per sibling comment, but also remember that kinetic energy also involves mass (planes are heavy) and the square of the velocity.
* https://en.wikipedia.org/wiki/Kinetic_energy
The latter is why (e.g.) going 100 units/hour has twice the KE of going 70 units/hour in a car.
It looks like that is based on the last recorded speed from flightradar24[1] which was 21kts(24mph). The previous data points were 11kts, and 58 kts(the last point before the track deviates off the runway). I do think it is likely that the collision occurred at a speed faster than 24mph.
edit: Looking into this a bit more it looks like the plane came to a stop around crossing E while the emergency vehicle was crossing at D(based on ATC recordings). Using the following map as reference[2], the 58kts point was around E, while the previous recorded point which was just before D was 114kts.
[1] https://www.flightradar24.com/data/flights/ac8646#3ede6c39
[2] https://www.flightaware.com/resources/airport/LGA/APD/AIRPOR...
Very unlikely it was 24mph…The entire cockpit is gone.
(Though some of the major damage may have happened while deplaning the passengers)
On other hand planes are really not designed to be crashed into things. Only for limited impacts. So we might not have right comparison for relatively thin and aimed to be light structure being impacted by bulkier object.
Speed doesn't cause damage. Momentum causes damage. We understand speed, we do not understand momentum. It makes sense given our evolution.
People into boats need to understand this. Even a boat that travels no more than 4mph can crush you easily. This is why you never get on to moving boat from the front. Many people have made a mistake because speed is not high.
Tugboats bump other boats all day. Hundred thousand pound pieces of machinery bury themselves into the dirt. All this as part of normal operation. It's not that simple.
Speed, kinetic energy and acceleration are all interrelated and at the end of the day it's all forces (to some extent) and no amount of hand wringing commentary is going to replace genuine understanding of them.
Avoidable catastrophes indiced as a measurement of cultural decline?
I saw the first post about this on /r/flying and /r/aviation 5 hours ago and legacy media is only started reporting it in the last hour or so
/r/xyz doesnt need to fact check. Sure those are excellent subs but just being watering holes and not legal entities they can move faster. There were some wrong facts on r/aviation although it got viral so people just ploughed in with whatever news outlet they read it on.
I have seen a lot of first posts on social media which have been wrong
Nope.
CNN, CNBC, NYPost, Guardian all had stories up quickly, or around an hour. There are others too.
UPDATED:
Down-votes happen but disappointing since I'm stating facts. Heres some backup:
The user haunter said media started reporting around ~4 AM EST (based on timestamps).
The accident happened at 11:40 PM EST. Story publish times across a sample of various legacy/mainstream media orgs:
There are others.Is this a dig on legacy media? Do we expect people to be up all hours of the day reporting the news?
I got a NYT alert about this around 3:30am EDT.
Yes. Yes, we do. I expect a competent news agency to have a night desk.
Why though? To report to the people who are asleep?
And so much of the legacy media info is wrong. It’s strange because a lot of the primary sources are public.
This is a good overview so far:
https://m.youtube.com/watch?v=8vokLcNNGCM
Very informative, thanks for the link!
ATC audio is https://archive.liveatc.net/klga/KLGA-Twr-Mar-23-2026-0330Z....
The clearance for AC8646 to land on runway 4 is given in a sequence starting at 4:58. "Vehicle needs to cross the runway" at 6:43. Truck 1 and company asks for clearance to cross 4 at 6:53. Clearance is granted at 7:00. Then ATC asks both a Frontier and Truck 1 to stop, voice is hurried and it's confusing.
> And so much of the legacy media info is wrong. It’s strange because a lot of the primary sources are public.
You should provide sources for a claim like that. For example, what in the BBC article is wrong?
If only we could diff the BBC article (it currently says it was posted 21 mins ago which is younger than your comment…). It’s changed multiple times now without any kind of changelog or acknowledgement.
> Video footage on social media showed the aircraft, which is operated by Air Canada's regional partner Jazz aviation, coming to a rest with its nose upturned.
This just isn’t true. There’s no video of the plane coming to a rest with its nose upturned (which implies motion). The upturned nose happened only after passengers deplaned and the balance shifted.
> It had slowed to about 24mph when it collided with a vehicle from the Port Authority of New York and New Jersey, which runs the airport.
This is the next part that will change. Just because some of the last broadcast data said 24mph doesn’t mean that’s the speed it was when it collided with the truck. The truck is on its side and those passengers are in hospital. The pilots are dead. The plane sustained enough structural damage to have the entire nose collapse. If the sentence is based on that broadcast data, SAY THAT instead of printing it as fact.
And with all the quotes from social media posts from key groups, link to them instead of just vaguely quoting.
EDIT:
As expected, they got rid of the above paragraph claiming the speed. It now says:
“The plane was arriving from Montreal and had landed, before colliding with the vehicle from the Port Authority of New York and New Jersey, which runs the airport.”
Any of us can help log the changes by submitting revisions of the article to web.archive.org
With a fast-changing news story where vague/incomplete/conflicting details emerge in the first few hours it's not unreasonable for the first few revisions to be like that, and eventually gets fixed hours or a day later.
I think that’s what’s critical here. Post details and their sources to show that they are in flux. Don't write them as fact and then make secret edits.
Typically most primary sources are public.
It's hardly worth checking with the legacy media anymore. Really, why bother?
Why bother with the facts when you're already heard all the gossip?
At the very least it’s worth reading to see what most people / the people in power are reading or want others to read.
The NYT is biased, but it’s still basically the most official newspaper of the American ruling class.
Because some of them still have standards. They will correct themselves if something was wrong.
Everyone can write a comment on Reddit / make a podcast / video / whatever claiming whatever they want. Unless you already know and trust them (which requires you to be able to cross-check their information), it's potentially as useful as a random LLM hallucination. Could be brilliantly spot on, or could be completely nonsense. No way of knowing unless you already know enough. (Because even cross-checking won't necessarily save you, if you cross-check multiple bullshit sources).
Media with standards (like the BBC, Guardian, Liberation, etc.) will do their best to report truthfully (even if sometimes with some bias), and will fix their mistakes if they're caught later on or the story evolves. Independent media checking organisations have shown time and time again that there is trustworthy media, you just need to know which it is, and always take a pinch of salt. It's wild to me that people will just dismiss rags such as Fox News and relatively quality media like Guardian in the same breath.
Introduce a foreign object onto the runway and it will inevitably collide with an aircraft. The fire trucks aren't part of the airport traffic management system, their sudden presence is bound to lead to problems eventually.
It wouldn't surprise me in the slightest if the truck has a single radio (airplanes always have two) and was constantly switching between ATC and fire house frequencies. The probably never heard the "stop, stop, stop stop.."
It would also not surprise me if airports previously had dedicated fire services, which have since been outsourced for cost reasons.
This is an airport-specific vehicle that was on radio with ATC at the time and had clearance to cross the runway. Nothing in your comment is correct.
And yet you chose to respond! Indeed I stand corrected on the onsite firehouse, LaGuardia does have one but many airports do not.
Bullshit. Pretty much every airport that handles FAA Part 121 flights has dedicated firefighting apparatus and crews.
According to this article, the air traffic controller gave the fire truck permission to cross the runway. So, it seems like they are part of the air traffic management system?
