The 9/11 conspiracy theorists are…well, loony tunes:

On who committed 9/11:
-Washington Post 11/01/04: Osama bin Laden says he had personally directed the 19 hijackers. In a video, he says: “We had agreed with the Commander-General Muhammad Atta, Allah have mercy on him, that all the operations should be carried out within 20 minutes, before Bush and his administration notice.”
-11-28-07 AP Cairo. Bin Laden said: “The events of Manhattan were retaliation against the American-Israeli alliance’s aggression against our people in Palestine and Lebanon, and I am the only one responsible for it. The Afghan people and government knew nothing about it. America knows that.”
-12/13/01 The Council on American-Islamic Relations (CAIR), a Washington-based Islamic propaganda group, said this regarding the videotape of Osama bin Laden: “For anyone who was not convinced of Osama bin Laden’s complicity should remove all doubt. Bin Laden clearly spoke as someone who had foreknowledge of the attacks.”

On what brought the towers down:
-The American Society of Civil Engineers, ASCE, with a membership or affiliates numbering over 270,000 engineers, endorses the 9/11 Commission Report that the jets brought down the WTC.
-Anyone who has watched documentaries on large building demolitions on the Internet and the History channel knows that it takes weeks for dozens of workers to noisily weaken (using jack hammers and acetylene torches) the support beams; then they plant the explosives (300 tons required for both towers, according to an ASCE estimate) and interconnect the explosives with miles of wires. But still, the conspiracy types think that 20,000 people who worked in the WTC didn’t notice this activity!

Conspiracy theorists, the world is ending in 2012! Take cover!

there are plenty of unanswered questions regarding 9/11
