This just in from the Comments line, even though it's been floating around for a while: ---
"It's been a few years since 9/11, but I cant help but to wonder why I can't find a single legitimate news article about this footage. It shows the BBC reporting live that the WTC 7 building has collapsed while it is in the background still standing. Then it collapses a few minutes later. So how do you do a press release that a building has collapsed before it collapses?"
