Well if you wish to be pedantic, perhaps I should have said "shell". The point being that the mass of the plane is concentrated in the solid parts, and not in the hollow parts which are filled with air. Momentum = mass X velocity. Where is the mass of the plane?

I'll ask my brother who has a degree in aerospace engineering.
Yes I would expect that there is more mass in the shell than air. But this is ofcource long and complecated issue, the planes and the damage on the 9/11.

For exemple in the Pentagon case the damage inside the building is all to much to be explained with a plane or plane parts. And the experts who tried to explaine it officially, obviously knew that very well and what is interesting to me is how they explained it. Can be seen here and in Pentagon Building Performance Report (2.5 MB)
(And they dont try to explaine the so called exit hole)
