We are discussing quite a few fun points on the AAP Tin Foil forum.
If you have fast-ish connection *click* to see the gif of the WTC 7 collapsing, courtesy CBS.
This building housed the offices of Con Edison, the FBI and the CIA.
"WTC-7 was a 47-story building and became a two-story pile of rubble, making it the first major structure in the United States to collapse because of fire."
My favorite, so far, Serendipity.
