The official story of what happened aboard UAL93 is depicted graphically in the film, “United 93"– the pilots are attacked by knife-wielding hijackers who stab them to death and thus take over the cockpit. I’ve always been suspicious of this story, especially since one of the passengers, Tom Burnett, reported in a phone call to his wife that the hijackers had a gun. When Burnett’s wife Deena was questioned about the gun report, this is what she said:

“He told me one of the hijackers had a gun. He wouldn’t have made it up. Tom grew up around guns. He was an avid hunter and we have guns in our home. If he said there was a gun on board, there was.”

That’s pretty convincing to me. The guns would also explain why the crew on only one of the four flights (allegedly) were able to make any kind of a distress call to ATC. Finally, there is documentary evidence that Betty Ong reported a shooting aboard AAL11 in her phone call, which was subsequently covered up. (I would be happy to go into detail about this evidence for anyone who is interested.)
