My math teacher has made up a conspiracy theory on 9/11.
He thinks that the American government, Bush, in general, set up the event by placing charges in the Twin Towers.
When the charges blew, the beams melted, and the towers collapsed etc. etc. He thinks the two 747's were highly advanced holograms which were beamed from the tower directly, and the projectors (with other aiding sources placed elsewhere) were right next to the charges, so when the airplanes "crashed in", the charges blew up, and thereby eliminating the hologram of the 747's.
To him, this was all a plot for Americans to hate Muslims, and an excuse for him to start the war on Terrorism in Iraq.
I DONT BELEIVE ANY OF THIS, but I thought it was an interesting topic to bring up.
