"This footage was posted to video sharing network Veoh.com on November 1, 2008. No information or data accompanies the video and there is no sound on the original file. The video was posted... by “GldBr,” a user with no other videos or information."The first two minutes of this video are of Building 7. Remember, this is the building that wasn't hit by any planes. Its fall was officially attributed I think to fires in the basement and collateral damage from debris hitting it when the twin towers collapsed.
Many observers have noted that the building drops in free fall. It doesn't successively pancake one floor onto the next - it freefalls to the ground unimpeded.
What's interesting in this view is at the 0:20 mark - before the building starts to collapse - seven vertically aligned windows near the right front corner appear to blow out. I'm not saying this is a controlled demolition. But it does illustrate the way a controlled demolition is achieved - by instantaneously blowing out the support columns.
The second part of the embedded video shows apparently new footage of the North Tower of the twin towers; it's interesting that the central elevator shafts are still standing as the cement dust cascades down, but that doesn't prove anything.
