> 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.
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:
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.
Fortunately, personnel from Morgan & Morgan™, America's largest billboard personal injury law firm, are rushing to the airfield to investigate the accident, take statements and offer their services to the injured to insure that they are properly compensated. "The way we plea, there is no fee."
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.
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.
> 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.
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.
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.
I am not aware of any data that supports the claim that there are more incidents in recent history. The safest years were, of course, the COVID-19 shutdown years, when air-travel was greatly reduced. But besides that the last couple of years has been overall safer than the years before COVID-19.
The 2025 crash near DCA, of course, absolutely spiked the number of recent commercial aviation deaths, but we haven't had any other aviation tragedies of that magnitude in more than a decade.
This can be a preventable tragedy without there needing to be a conspiracy behind it.
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 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.
> 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?
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.
> 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.
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).
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 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
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.
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.
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
"each one should be investigated as if an accident occurred and fixes proposed"
I feel the same way about close calls on the road, especially ones involving a vehicle and a vulnerable road user like a pedestrian or cyclist. Way too many lives being saved by a person jumping out of the way at the last minute who shouldn't have had to do so, and then cops and bureaucrats shrugging with "well what do you want us to do, the numbers don't show enough fatalities here for it to be worth fixing" and later when someone actually does die it becomes "this is a horrible tragedy that no one could have seen coming, let's focus on thoughts and prayers rather than accountability that could lead to structural change."
There is a certain class of person who will take something simple like, say, brake lights on a car, and extrapolate it out to industrial control systems of something incredibly complex with demanding safety requirements and "observe" "it can't be that hard can it?"
I remember a debate a year or two ago about a plane ignoring instructions (IIRC it had changed frequencies) and had taxiied onto a runway when a plane was landing. Luckily the landing plane saw this and do a go around so nobody was harmed.
In the aftermath, there were similar complaints to yours. "Why can't they just have lights to block planes when a departing or landing plane was using the runway?" without thinking through how any of that works. For a start:
- How do you allocate that a runway is "in use"?
- If ATC does it, what if they fail to turn the system on?
- What if turning it on or off fails?
- What if it gets stuck on or off? How do you fix it? Are there procedures for ATC to override it anyway?
- There are multiple entry points to a runway. What if they're in different states?
- What company si going to sell such a system and accept liability?
- What training requirements will be needed for ATC and the pilots?
- What do you do if a pilot goes ahead and ignores it?
I think people can't think beyond cars. Cars have had unimaginable effort put into them so they can only operate within a certain window. Even then they require maintenance.
But as soon as you scale up to industrial safety and control systems, a power plant, the engine on a ship, etc you will end up with a bunch of controls where the people using them need to be skilled operators and it is essentially impossible to eliminate mistakes with automation and IT systems. You will need overrides. You will need redundancies. You will need to end up doing things nobody has ever considered before and have to rely upon training, education and experience to go beyond the envelope. That's just how it works.
What you are describing is sometimes considered to be part of the mythical Cat IIIC standard. The gap between Cat IIIB and Cat IIIC is being able to fully automate the entire taxiing and other ground manoeuvring. It is widely considered to be impossible to achieve safely with current tech. It does feel like the future though.
This isn’t really ATC though connected. I was just watching a presentation from Royal Schiphol today about a lot of the automation of the airport they’re putting in place as part of admittedly long-term 2050 plans. Lots of computer infrastructure rework.
I'm a ground instructor and instrument rated pilot and I fly a 206 in and out of busy charlie and delta airports. I'm also a ham radio guy (WT1J) and an SDR dev. I'm 100% with you on this, but the amount of inertia you're dealing with here approaches infinity. And there are some weirdly strong arguments for not changing things.
We use AM simplex radio. That means everyone hears everyone else and that helps everyone build a situational awareness picture. Secondly we use AM because if someone transmits over someone else it makes a squealing noise so you know it happened. Also AM propagates pretty well.
Most people on HN could design a pretty good digital replacement in a few minutes - and no doubt some have been suggested in these comments. But its instructive to understand a bit about aviation history. The liability risk carried by aircraft and avionics manufacturers at one point go so bad that we stopped making general aviation planes in the USA. Then that liability was limited to a very small extent by GARA, and we had what we call the 'restart' of manufacturing.
So the idea of introducing a new mandatory replacement (not addition like ADS-B) for AM comms has a lot of resistance from quite a few areas: Manufacturers don't want to have to make the capex to reinvent and recertify new equipment. The US has a lot of old planes due to the lack of innovation because of the liability issue - and so those old planes all need a retrofit and pilots don't want to spend that money. Avionics for certified aircraft is already horrifically expensive. Legislators don't want to take on the risk of an incident attached to a bill they sponsored. And then there's the practical matter of now having two systems - the legacy AM comms, and the modern one that some have and some don't and the split in situational awareness between those populations.
So while full-duplex is seductive, and digital is seductive, and satellite seems like the obvious endgame - the reality of transitioning is very difficult.
Vehicles are listening to the same audio the pilots are, so they have the same mental picture of what's going on. Last week I talked to a maintenance vehicle at KBLI directly from the air because he was on a runway I needed to land on, at an untowered field. He cleared it, I landed, and he went about his business. So the system works pretty well most of the time.
I think the root of the issue here is actually something else. Firstly there is a lot of dissatisfaction among NATCA members (ATC union) towards their union, and the view seems to be that the union could be doing a lot better job of lobbying for their workers. You can visit /r/atc or /r/atc2 on reddit to learn more.
Secondly, the USA has fallen into a nasty trap where our government has positive incentives to choreograph shutdowns to get our congress members and senate members the face time that they crave. So there is a negative incentive to resolve a shutdown. Rather let it get hot, let it play out, and maybe you'll be the one to appear to save the day to your constituents. The trouble with this is that the department that creates one of the highest risks for civilians in a very visible way, is the FAA and the controllers in particular. So they have become a political football. And they're in an extremely stressful job without pay. And that's a very big problem.
You're seeing this play out in a growing adversarial relationship between the NTSB (e.g. DCA) and FAA, with NTSB tearing FAA a new one recently for DCA - and rightly so. I think that's led to more demotivation at FAA which hasn't helped.
So the situation is spiraling out of control. We have controllers who are overworked, who regularly don't get paid, and a union not doing the greatest job at advocating for them. Along with the recent cuts in government funding across the board.
It's frustrating for pilots. The best we've been able to do is bring our local TRACON folks stacks of fre...
With the current atmosphere around technology, I feel like "digitize air traffic control" is an idea that will be both executed terribly by the money grubbing lunatics in control the government and tech corporations, AND received poorly by the public.
I wrote my university thesis 25 years ago on automating some parts of art traffic management. The fact that it's "humans over radio" coordinating everything sounded ridiculous already back then.
but it's still "don't fix what ain't broken" situation - the system works surprisingly well, if you think of it, and nobody has balls (nor political power) to truly reform it.
i’m at the point where i’m pretty much never going to put my family on a plane unless we have a very urgent reason to visit family overseas or something
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.

Grok timed out but here is perplexity
Per 100 million miles traveled
This means driving has roughly 190 times the fatality rate per mile as commercial flying in the U.S.umm u should never drive again. in fact never leave your apartment/house.

Truck declared it was crossing. ATC told it to stop. Truck didn't stop.
This wasn't a communication issue.
The truck asks permission to cross. It is given. The truck declares it is going to cross, but the ATC replies "just stop there please".
Also, those runway entry lights look red to me. If so, that should have been a HUGE warning sign to the driver.
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.
ATC audio
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.

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...
