Let's see if a conspiracy theorist can honor their word.
1. The plane http://en.wikipedia.org/wiki/United_Airlines_Flight_93#mediaviewer/File:N591UA.jpg
2. The same plane spread out over an area after crashing at over 500MPH http://en.wikipedia.org/wiki/United_Airlines_Flight_93#mediaviewer/File:Flight93Crash.jpg
Given the number of conspiracy theorists, they should have no difficulty buying a plane and repeating the conditions of the crash into the same location (just need one volunteer with enough brain cells to pilot it).
Of course if there is really any doubt, cell phone GPS signals can easily be traced to their cut off point. The number of cell phone company employees that would need to be in on it to fake that, would make it nearly impossible to keep secret for even a single year.
Lots of people don't like the truth I guess. Lots of sheep out there. Preston if you want to black list me, it is because I tell you things you do not want to hear. When the 9/11 commission members do not believe the official story, why on earth do you sheep still believe it?
Go look up Max Cleland on YouTube. He was on the commission and doesnt even believe the commission findings. Go look. Why on earth would you be so stupid to believe something when the people who created it do not even believe?
So your source is an EX senator, who was a critic of the White House. So his job was to disagree with the with house, sounds reliable, you know the other 50 senators who where actually senators at the time agreed but whatever.
