Why don’t you jump in a pool of water from a mere 200 feet up and see how your feet feel. And if you still don’t believe me, jump from the same height face first.
I am sure it would really, really hurt and probably mangle up my body quite a bit. But that tells me nothing about how a massive airplane would react to the impact.
To say nothing of the assumption that the plane was going 500 knots. How has that been shown?
