Wasn’t poor visibility also a significant factor in the Tenerife airport disaster? https://en.m.wikipedia.org/wiki/Tenerife_airport_disaster

The Linate incident is also similar https://en.m.wikipedia.org/wiki/Linate_Airport_disaster

Just to give a little context as a pilot: It is the job of the tower controller to decide who uses the runway when. There are often multiple planes waiting to take off, and multiple planes nearing the airport to land. It's not uncommon for a tower controller to allow a plane to takeoff while another is approaching the runway. The theory is, of course, that the flight will depart in plenty of time. In this case, the c…

I'm not sure how many people know this, but one of the first instances of "union busting" ever committed by the US federal govt was against air traffic controllers. The job used to be extremely competitive and prestigious, but overall lower wages and security has made it way harder to attract as many highly talented individuals.

And with how many rules there are in that pdf, it's shocking we don't see multiple accidents a year.

When we have major line-of-fire incidents on our sites that can very possibly result in loss of life, generally you do get the boot. And it is certainly not 'hidden', you get black listed and company-wide communications are sent as a result. People certainly do learn from these kinds of mistakes, but usually the person at the centre of it goes for a walk.

What industry would that be and how is your safety record?

Mining, and what kind of inane line of questioning is that.

I don't knock unions but I will add :

> The median annual wage for air traffic controllers was $129,750 in May 2021

SOME unions do take advantage, given the traffic controllers' 'single point of failure' it can be very attractive for some unions who are greedy. Again I reiterate, unions are not a bad idea, just not all of them are solely in the interests of the actual employees.

Air trafic controller strikes have plagued our country (France) for many years and I see no indication that it makes our flight safety better

Sounds like a job for... A.I.?

No, no and no. Safety critical systems must be validated to be safe in the operational domain and for that they must be deterministic. AI is anything but that.

AI is entirely deterministic. ChatGPT and StableDiffusion and friends are fed endless amounts of random seeds along with every input to keep them from just saying always the same thing.

> he write-up doesn’t answer the key ”why” question —- why are existing procedures and training not suitable? This will be the job of the investigators but it sounds like obvious tower control human operator error.

It could be the fault of the southwest crew for dallying on the runway when there was an incoming jet. Had they gone immediately they would have been long gone by the time FedEx tried to land.

The pilots take off when they take off. If their take-off clearance isn't obviously time limited, they are certainly allowed to take their time. If they rush the take-off they might skip crucial items from their checklists in the haste, we learned that lesson the hard way already. Or what would have happened had the southwest jet had an issue on take off and had to reject? There is a number of reasons to reject a take off before decision speed that will take the plane down the rest of the runway on full brakes.

Flight in airports are not safe without air controller. It doesn't make it better, it's a requirement to safety.

The output for a given input (absent random seeds) may be constant, but is the output deterministically correct?
