Oops... my mistake. I don't remember which flights were which and I mixed them up. The one that supposedly hit the pentagon, flight 77, is the one I think was shot down over the ocean. The one that went down in Pennsylvania... whoever thinks that was shot down is a rough ridin' moron.
But the pentagon, I think the damage would have been much worse if a 757 hit it . I think it was hit by a missile from a fighter jet - likely the same fighter jets that were instructed to shoot down the unresponsive flight 77. I think it would have been very difficult for an inexperienced pilot to hit something as small as the pentagon at the speed suggested, and it was odd that it was a side of the building that was being renovated - so casualties were limited, and the aforementioned incredible lack of damage that would have been caused by a 757 hitting a building.
