Mainly heat. It heats the parts by crushing them and all the pieces inside.
If you had a sensitive thermometer and the plane did not explode, you could work out the amount of kinetic energy involved, at least a decent estimate by noting the temperature of the rocks and/or the pieces left over versus the temperatures of the plane chassis and wings, etc., ...[text shortened]... .
Everything will be very hot for a while anyway, till wind and/or rain sucks the heat away.

they would not need to be very heavy, after all their function is merely to clamp and release.
You have also just seriously weakened the structure of the aeroplane.
Which means you now need to significantly strengthen the remaining structure.
Which adds weight.

In the US flight regulations insist that there be at least two people in the cockpit at any one time, with a member of the cabin crew standing in if there are only two flight crew. The EU does not have this regulation. Had the EU had this regulation the co-pilot would have been prevented from doing this by the presence of another person. So that's the systems change to reduce the likelihood of this kind of incident. It would require two people to conspire which given the nature of the conspiracy is incredibly unlikely.

Yeah, it's difficult to introduce systems to prevent a person deliberately crashing
the aircraft.
The only solution to that is to have the aircraft able to auto-override the pilot.
Which is possibly where we will eventually go, but it's a very fraught subject as
pilots understandably don't want ...[text shortened]... incidents like this [assuming that this is what it currently looks like] are incredibly
rare.

The post that was quoted here has been removedThe thought occurred to me that it could be Muslim terror but I feel sure he would have yelled something like Allah is Great or some such just before it crashed.
Not hearing that, I would conclude the dude had a cognitive break, some kind of mental breakdown, maybe something will turn up from the cops raiding his house, notes, X gf, something like that.
Originally posted by C HessWhatever system is introduced there'll be a way around it. Having two people on the cockpit at all times would introduce a barrier to doing it, basically by reducing the chances of a potential culprit getting past the planning stage. They used to have three people on the cockpit as a matter of course. Pilot, co-pilot, and engineer. They no longer have the engineer, basically because the plane doesn't need them. They could be reintroduced, but that would mean paying an extra set of wages for each flight for someone that isn't really necessary. Screening their aircrews for narcissistic personality disorder might be more cost effective.
Or, the suicidal one could have just knocked out the second person, before locking out the rest and steering the plane into the ground. I think the regulations should have at least three people in the cockpit at any given time.
What would *you*, as a pilot of an commersial airliner, do if your daughter (wife, sister...) is kidnapped by an evil organization, telling you that they will kill her if you don't crash the plane you are in charge of.
Would you just refuse and live with your loved one would die? Would you tell the police, your boss, or anyone, so they could solve the situation? Or would you just crash the plane in order to save your loved one, even if you die yourself together with 149 passengers? And in this last case, would you write a suicide letter explaining the cause of the crash or would you just hope noone would find out about the truth?
What would you do to crash the plane? How could anyone else prevent it?
This hypothetical question could give the answer how this plane crash was possible.
Now it appears that the co-pilot had some mental problem, and was not supposed to fly that day, per his doctor. This info seemed to surprise the airline, which opens up the question: Shouldn't people who pilot commercial planes forfeit their privacy to ensure our safety? Shouldn't airlines have every right to any knowledge about their pilots that may endanger us? If you want to pilot a commercial jet, maybe you should expect your personal life to be an open book to your employer.
