Is This Video and Audio Proof of Explosions in WTC 7? On Second Thought, Probably Not.

If this isn't a doctored video -- and it doesn't appear to be doctored to me -- then we now have
 video and audio proof of explosions in WTC 7 just before its collapse.

UPDATE:  This site claims it's a fake, which would explain why the 9/11 Truth movement hasn't been using it.
