We are at an inflection point.
We could concentrate on giving people training in exactly what they need most when they're needed: When it gets hard. Even starting and landing an aeroplane is a solved problem, at least in fair weather, so there's hardly a reason why you'd have three pilots on board just for that. We might even have been better off with just two in this case: The one co-pilot might've called the captain back much sooner. But that is highly speculative, of course.
What killed everyone aboard was, as I read the transcript, two juniors getting stuck in a panic over a situation that a more experienced pilot mightn't have batted an eye over, and nothing that might've snapped them out of it. They've basically stalled themselves into the sea, and didn't notice--apparently this is possible in a big aeroplane. The simplest fix might even be to make the stick generate feedback both about the other stick and about the rest of the machine. You know, force feedback like you find in your favourite game console.
It is perhaps a testament to how good the technology is that it goes wrong so little, but this transcript does show that the tech has left those in charge of keeping the passengers alive short handed when the technology does drop the ball. Both on feedback, and on experience.
We could also build systems that never give up, not even when it gets hard, and drop the pilot from the equation. We simply do not allow the thing to drop the ball, ever. How? I don't know, I don't design aircraft for a living.
We cannot now mostly because of legal reasons --need a human to blame, rightly so-- but technically, well, those drones already take off and land themselves, routinely. They then manage to get themselves caught, but anyway. And even if we changed the law and we could somehow show that we'd be better off without human pilots, I would probably personally still pass on flying with such a thing, full well knowing it would be on frankly irrational grounds. That, however, doesn't change the argument:
It is clear that solving the easy stuff has had a side effect that the hard stuff will now be left to humans with irrelevant experience. This, too, we need to solve, this way or that way.
Sad? Yes, of course. It is a tragedy, a disaster. Yet the only way to learn is to study the whole thing regardless, draw hopefully correct conclusions, learn. That is something that the flying boys thankfully haven't forgotten.
