[Winter wind]

My boss saw a plane hit the buildings. My cousin saw the planes hit the buildings. The planes hit the buildings. (Unless they secretly work for the government as well...)

And to the argument that they were brainwashed. If they were, I would hear "At first I thought it was some kind of massive laser, but now I realize it must have been the planes." Instead I hear "I saw a plane fly right into the building."

However, I have no opinion on the concept that the United States had a hand in the attacks, though I find it unlikely that the United States government would have the guts.
