Video footage posted on YouTube refutes NIST's claim of no evidence for explosions in WTC7.

At the media briefing on the NIST Investigation into the Collapse of World Trade Center Building 7, August 21, 2008, lead investigator Dr Sham Sunder claimed "We did not find any evidence that explosives were used in the collapse of Building 7. We ran down detailed computer simulations of blast scenarios - what you see in the slide are the expected air pressures from the smallest possible blast capable of crippling a critical column. This size blast would have produced an incredibly large sound that was not recorded on videos of the collapse nor reported by witnesses"

Video footage shot near the pay phone at 66 Murray St, approx 150 m from Building 7...

showing first responders using the pay phone, provides evidence of a very large blast sound near WTC7 on the morning of 9/11, sometime after the destruction of the Twin Towers. One of the first responders is heard to say "We've gotta get back, 7's exploding."

Another video shot near St Paul Chapel, approximately 250m from WTC7, also provides evidence of a very large blast sound near WTC7 on the morning of 9/11,

These videos refute the claim made by NIST to justify their decision not to look for evidence of explosives used in the demolition of WTC7. These videos has been ignored, overlooked or denied by NIST.

There are also credible and corroborating claims made by Barry Jennings and Micheal Hess that they witnessed explosions while inside Building 7 on the morning of 9/11. These eyewitness reports have also been ignored and denied by NIST investigators.
