> That one controller was handling both ground and air ... Why do you (or why does anyone) think that? My point in the GP was, I have yet to see evidence that there was only one controller, and I have seen evidence that there were two.

Because in the ATC recording you hear him directing both

I get it now. That's of interest, definitely, but I wouldn't conclude it was universally true - that the one controller did both for everyone.

In this specific incident, there was a system in place called Runway Entrance Lights [0] that does serve as an automated sanity check on controllers commands. The surveillance video that is circulating shows that the system was working and indicated that the runway was not safe to enter. It's not clear yet why the truck entered the runway anyway. 0: https://www.faa.gov/air_traffic/technology/rwsl

The REILs are part of ARFF training. Pilot training on it is also clear. The system is automated. It plots the direction and speed of anything approaching the runway and predicts a conflict. If the REILs are red it is HIGHLY likely there is a conflict that is missed by human error and you should not proceed without confirming. Don't just confirm cleared to cross, explicitly tell the controller "XYZ tower we have red…

> the holes in the swiss cheese lined up.

I totally agree with you on that.

> The emergency aircraft couldn't find a free gate, creating a massive distraction for ATC, airport, et al.

Yes. And I want to add one more thing to this: the airplane with the "odour" issue was kinda ambivalent about the danger. They deemed it dangerous enough to declare an emergency, and request a gate then later ask for airstairs but not dangerous enough to pop the slides and just evacuate right there and then. I'm not saying this is wrong. Obviously they were evaluating the situation as new information was coming in. But it increased the workload of the ATC. They were trying to find a gate, and etc. If it was a clearer "mayday mayday mayday, aft cabin fire, we are evacuating" that might have been paradoxically less "work" for the ATC. Or at least more of a "practiced" scenario.

> Perhaps it was some other misunderstanding of how that system works.

Yeah. That's a big one. Total speculation but maybe they thought the airplane with the "odour" issue was keeping it red?

I wonder if they thought that since they were responding to an emergency, and they were given clearance to cross by ATC, that that would override normal procedures. Kind of like how emergency vehicles cross a red light all the time when responding to an emergency.

If they thought that, it was in error. Training SPECIFICALLY calls this out. The lights ALWAYS overrule the controller. Period.

It would be interesting to know whether that rule was onerous enough in practice that they had little choice but to break it in order to do their jobs effectively. They were responding to an emergency, seconds count, and they believed they had clearance from the controller.

I actually can't remember or imagine another POTUS even getting to a level of specificity required to scapegoat an individual for something like this. The usual (and correct) answer is to say: "We don't know yet what happened, but there will be a full investigation and we will make the changes necessary to prevent it from happening again." Pretty easy! It doesn't serve us well to act like this administration is anyth…

Look, if you were to review my comment history you would have no doubt about where I stand on the current administration. But scapegoating any single politician for the systemic problems of aviation is as unhelpful as scapegoating the controller for the crash at Laguardia.

I didn’t see anyone scapegoating him for anything other than engaging in direct personal attribution which is counter to aviation safety culture, basic leadership principles, and minimum decorum standards ¯\_(ツ)_/¯

extremely aberrational Is it still an aberration the second time 'round?

Yes

You don't need a union to have effective management. It should also be their incentive not to cause people's death by overworking employees. Which is also dumb because it costs more to overwork then hire appropriately with overtime laws... cops exploit this all the time to steal money from taxpayers. (The ones in Seattle only get caught when they accidently charge over 24 hours of overtime in a day) Union rules that…

> It should also be their incentive You can't just proclaim what incentives should be. We do have a mechanism for changing the incentives of management though: it's called unions.

If it was a traveler's union, maybe. Cop unions don't result in better outcomes for the general public, and there's no reason a controller's union won't end up just boosting pay and having a rubber room for hacks (referencing NYC schools paying teachers to not work because they're either predators or terrible at teaching, but being unable to fire them).

LaGuardia did have a fully staffed ATC, and there's zero evidence this controller was overworked. You seem to be prematurely ascribing cause when nothing has been investigated yet.

The parent post was unjustly flagged for no other reason than facts make overly emotional people here squirm with anger. Pathetic and lame. This is worthy of losing flagging privileges IMO. The Secretary of Transportation said on record at the first press conference that reports this guy was working alone in the tower are INACCURATE. The actual number is the responsibility of the NTSB to disclose. 95% of this discuss…

From VAS Aviation, https://www.youtube.com/watch?v=Pbm-QJAAzNY, or possibly in the comments, it was noted that there were 2 people on - one in the tower, one elsewhere in charge of approach. So perhaps, it's innacurate because he was working "with" the person on approach, but still accurate to what we would all call "working alone"?

I just hope they don't try to pin this on the controller who was on duty and move on without putting plans in place for some sort of structural change. Controllers are forced to work 60+ hour weeks and overnight shifts, and the controller in question was working both ground and air control simultaneously due to staffing shortages. If you listen to the ATC audio, he was handling finding a spot for a plane that aborted…

Is it possible to automate the job of an ATC controller? At least partially? Or at least just as a sanity check on every human decision? Not saying I want human ATC controllers replaced, but if there’s a severe staff shortage, I feel like a computerized version is better than nothing at all.

A great deal of ATC relies on automation, such as systems like ASDE-X, which is used at LGA. ASDE-X uses radar and vehicle transponders (among other things) to detect collision hazards on the ground. Unfortunately ASDE-X only works if every vehicle has a transponder.

The truck involved in the collision did not have one. https://bsky.app/profile/flightradar24.com/post/3mht7m2f3rc2...

Why cross a runway at all? Can they not use taxiways and aprons to get there?

There's a mountain of evidence. No single controller should ever be running tower and ground at an airport like LGA.
