do you know how fast that plane was going??? How much fuel was in that plane? Airplane fuel burns extremely hot and fast, so when it hit the pentagon, it literally disentigrated, and lit up that place.
I believe all of these attacks happend because of a massive breakdown in governmental inteligence-people saw it comming, but inteligence failed to pin down the attack to any one single day.......Lesson learned! Hopefully!
P.S. Did you know that Seth McFarlane overslept for one of those flights the day of the attacks??? He doesn't know if someone else got the ticket, or not!!!! Yikes!!!
