The plane disintegrated, that's how it showed it. There are several factors that differ from the Pentagon. #1 was the wall at the Pentagon as strong a the wall used in this experiment? #2 The tips of the wings went past the wall because the wall's width was less than that of the plane. #3 It is not a passenger jet. The comparison, at best, is weak, however, it does show that it IS possible a plane can disintegrate on impact. It does not show that Flight 77 disintegrated on impact. The 85 videos currently stored by the Government might. I have ALWAYS thought it was dangerous of the movement to promote the Pentagon/Missile/Global Hawk/Something other than Flight 77 theory. Especially now that we've proven mathematically that it WAS possible that Flight 77 hit the Pentagon. I just think any theory the Government is more than willing to "expose" in their critiques of the 9/11 Truth Movement, is a dangerous theory for us to promote.
