Well first off all that damn thing is a flash, goes way to fast, and doesn't let you rewind to retain any of the information. The one thing off the top of my head that was on screen long enough to make a point was the "can 757's poke neat holes in walls" the answer seems to be an obvious yes, that was shaped like an airplane fuselage if the wings had broken off, or if only the front part of the plane had made it that far.
Another obvious distortion of the fact is they show "pictures of intact windows" and similar things, but in an area where the plane didn't hit.
Basically the whole thing is a cute presentation that only raises one valid point, the confiscated videos, the rest is taken apart methodically on several websites such as
