1) The plane is going to be shredded and scattered amoungst the rubble of the building. I do believe they found a jet engine amoungst the wreckage.
2) Plane causes structural damage upon impact. Subsequent fire causes intense heat. This intense heat changes the structural properties of the metal frame of the building. This causes beams layed horizontally to sag and beams erected vertically to bow under the intense weight loads of several floors above them. Once one floor gives away a domino effect is started.

1) That's nice, why was that side of the Pentagon reenforced prior to the attack?
2) That's nice, why weren't any of the three planes intercepted by fighter jets, as all other hijacked or non responsive aircraft including small single engine airplanes are with 100% success within minutes?
