Even if you don't believe the video footage shows it was a military plane, the engine that flew out from the supposed flight 175 crash was a CFM56, no UA 767 in history has ever used that engine. It's over guys. It was a military plane and thus an inside job, 1 out of 10000 reasons.
2012 version was taken down, this version has more witnesses. For people who ask - who ordered 9/11?
