Ummm... are you casting doubt over 9/11? Quite clearly a senior citizen rallied a bunch of Arab men from all over the world who were apparently already on the CIA terrorist list. Those same bunch of men somehow got into the United States, stayed undetected for about a decade while taking flying lessons. They somehow smuggled stanley knives on several planes despite going through metal detectors. Then they used those same knives to get into an open cockpit while the passengers sat back and refused to fight/stop 2 men with knives and then they crashed the planes into buildings, the ground for some reason, and a heavily guarded US military building which wasn't able to show video evidence of an actual plane hitting it. And then within hours the main highjackers passport was found, intact, in the rubble of two 110 storey buildings.
What doesn't make sense to you?!
