There is a conspiracy theory about 9/11 and it goes like this:

"On September 11, 2001, the laws of physics were suspended, what was clearly observed did not happen, and anyone who questions the stories that were made up after the fact to explain away the obvious reality of the situation is an uniformed crank."

There a problems with this theory:

1. The original recorded eye witness accounts - before they were quickly massaged away by the news media and its controllers - were practically unanimous: There were multiple explosions in the three buildings effected which directly preceded their well-ordered collapses. (Yes, three - not two - buildings collapsed on 9/11.)

2. If we had a competent, ethical, and courageous news media in the US, the information on this video could have been presented on the evening of September 11, 2001. It's basic science and easily understood by watching the publicly available video tape with an informed eye.

"Who" and "why" and some of the details of "how" are still open to question. What happened is not.
