Very interesting. Two main points stand out for me: 'Founded in 1901, NIST is a non-regulatory federal agency within the U.S. Department of Commerce' from the NIST homepage and on the 'Failure Sequence Timeline' page of the presentation: '8.2 secs' for an amazingly complete pulverisation down to about the third floor. It just seems so incredible that such a massive building which wasn't struck by anything conspicuously large could simply drop so soon after anything at all was amiss.

I examined the NIST report, but I think the more compelling hypothesis can be found in the link I provided.

According to NIST, an intial column(s) failed which resulted in a "vertical progression" followed by a "horizontal progression." I'm sorry, but this building wasn't made of dominoes.

NIST also exaggerates what they call "disproportionate" collapse. If you watch the footage on youtube it is entirely consistent with other recorded demolitions. It is even more "proportionate" than most.

From the bottom of page six: "NIST has seen no evidence that the collapse of WTC 7 was caused by bombs, missiles, or controlled demolition."

I think the NIST is by far the most qualified body to be addressing this issue.

You are correct, but that aint a BBC video. The BBC bit ends where they get a state terror apologist to claim that if you knew how the buildings were constructed you wouldn't doubt that they fell of their own accord.

The BBC is covering this up.

Theres a BBC hit piece on WTC7 on Sun 6th where they will try and make the proof that WTC7 was brought down by explosives go away with more silly arm-waving.

I'm sure the forensic analysis of the wreckage ascertained exactly the cause - oh wait - all the evidence was destroyed!
