There were a number of cameras at the Pentagon...they released a like a 2 second gif of the explosion. It was neither big enough nor wreckage enough for a plane. It was also a recently reinforced area. It was also after Rumsfield said that they couldn't account for $2.3 trillion. Gold missing from WTC vaults was found on trucks, witnesses were chased away by armed men. WTC7 housed the 2nd largest CIA headquarters and all the SEC investigations, which were conveniently destroyed. It was the pretense for the war on terror, TSA, Homeland Security, etc. The list goes on and on. They spent more money investigating steroid use in the MLB than they did 9/11.
