Likely true.
We know that planes were dispatched to shoot down other hijacked planes.
This plane was known to be hijacked and it did not blow up when it hit the ground. It made a huge creator, but it did not "blow up".
Think about it. If you KNEW you were going to die at either the hands of terrorists or the millitia, and if at the hands of terrorists meant the death of other innocent people, would you seriously allow your plane to be taken over? No f'ing way! I'd ditch it in the most remote place possible. RIP the people on board, but to crash the plane into something populated (the WTC towers, the Petagon, etc) would be unspeakably WRONG.
Where did the fuel go? If you dump fuel at 20K feet at 250 MPH, the end result on the ground would be negligible. I could piss on you from a 10K foot parachute jump and you wouldn't even know it.
