That movie, like the websites I have seen about this "theory" is pure nonsense.
There were lots of airplane parts, and as anyone would half a brain would realize, when an aircraft hits a buildling like the Pentagon at over 250 mph, most of the parts continued on into the building, not bounced off onto the lawn.
Since the majority of aircraft structure is aluminum, those parts would be smashed into pieces and then melt into little puddles in a fire as hot as an aircraft crash.
I have seen photos of the engines laying at the scene, with one websight trying to say they are too small around to have been from a 757. Too funny, as anyone who actually knows anything about jet engines is aware, only the front, first stage fan is large in diameter. One set of blades. The rest of the engine, the "core" as it is called, is much smaller in diameter than you might think, and the cores they showed laying at the scene were exactly the correct size for a 757 engine.
I wonder what this freaking idiots are trying to prove? Were do they think that missing 757 is, and all the people in it? Why are they trying to pretend it would boune off the Pentagon, and not bore straight into it, where, loaded with jet fuel, it would burn intensely and consume the majority of the materials it was manufactured with?
Anyone who believes those conspiracy lunatics is missing many marbles.
