“And as to why it penetrated so far into the building, it was a large, heavy object carrying a tremendous amount of kinetic energy; it had to go somewhere.”
Again Borat, a soft object even when traveling at 500mph will hit a solid object and the energy will transfer into the wall not through it. I do a lot of shooting so this might help.
If you shoot a soft lead hollow point bullet at a cinder block the bullet will simply flatten out against the block. Much like the hollow shell of an aircraft.
Now if you shoot an armor-piercing bullet at the same cinder block the energy will be able to push the bullet much deeper and maybe even through.
The plane is a soft shell and not made of armor. Thats why bunker busters were even developed so we could blast through concrete and steel.
