and windows not broken where the wing tips should have hit.

Some give evidence that the plane had bombs with shaped charges that caused the penetration of the building but destroyed some of the plane before impact. There is a lot of evidence that the big explosion was high explosives(white color, then red, not orange like kerosine) and a huge shock wave consistent with high explosives. Also Pentagon employees in the explosion area said it was caused by explosives/bombs.

While there is considerable evidence a big plane and bombs impacted the Pentagon, it does not appear to have been Flight 77 and the attack on the Pentagon does not appear to have been an attack planned and carried out by arab terrorist. It hit the wrong part of the Pentagon and had to go to a lot of trouble to do that, and the people murdered were at odds with the Bush Admin. establishment, not someone the hijackers would try to hit. Those murdered were the Office of Naval Intelligence and the auditors who had found $2 trillion dollars missing or stolen from the Pentagon budget.
