Hilarious! No U.S. government agency can give the cachet of reasonableness to any "conspiracy theory" stating that Building #7 was brought down by demolition explosives... because that would by reference include the Twin Towers also. Inevitably that would lead to the question 'who did it?' because obviously then it could not have been the Arabs. (And that would lead - horrors! - to the Jews.) However, it is apparent to anyone with a high school education that Building #7 WAS  brought down by demolition explosives! Caught between a rock and a hard spot, The National Institute of Standards and Technology, a U.S. federal 'scientific' agency, has solved their dilemna...... by theorizing the existence of an entirely new physical phenomenon! We will stick with the conspiracy theory, though, because the NIST gig is just too much, waaaay too much!

As federal agency declares 'new phenomenon' downed WTC 7, activists cry foul

According to a federal agency report released Thursday, a "new phenomenon" known as thermal expansion was directly responsible for the mysterious collapse of World Trade Center 7 on Sept. 11, 2001.

This study, posed by the National Institute of Standards and Technology -- a federal scientific agency which promotes technical industrial standards -- marks the first 'official' government theory on the collapse.

The building's demise occurred some seven hours after the twin towers collapsed on Sept. 11, 2001, and has been the source of numerous conspiracy theories key to the "9/11 Truth" movement, most of which argue that the symmetrical, seven-second collapse was brought about by a controlled demolition.

Dr. Shyam Sunder, director of Institute's building and fire research laboratory, oversaw the government's three-year research efforts. The report aims to disprove the controlled demolition argument.

However, Richard Gage, founder of Architects & Engineers for 9/11 Truth and a member of the American Institute of Architects, doesn't believe a word of the theory.

His group, which has swelled to over 400 architectural and engineering professionals, immediately responded to the Institute's claim in a press conference.

"Tons of [molten metal] was found 21 days after the attack," said Gage in an interview with a Vancouver, Canada television station. "Steel doesn't begin to melt until 2,700 degrees, which is much hotter than what these fires could have caused."

"There are holes in this story that you can drive a truck through," Gage added during the press conference. His group asserts that thermite, a steel cutting agent, was used to bring the building down.

Dr. Sunder disagreed.

"We conducted the study without bias, without interference from anyone," said Dr. Sunder. "We have only one single-minded goal in this effort."

While the Institute said it considered the possibility of a controlled demolition taking place at WTC 7, the notion was dismissed due to the absence of any recordings of an explosion sound.

Thermite, however, does not make an explosion sound. And while this was raised to Dr. Sunder in the media's Q&A session, he dismissed it as impossible.

"FEMA found it," said Gage. "Dr. Steven Jones found it, in the dust that landed in the entire area of lower Manhattan. And he finds it in the chunks of previously molten metal [from the towers]."

Specifically, in Appendix C of its World Trade Center Building Performance Study, FEMA claimed:

Evidence of a severe high temperature corrosion attack on the steel, including oxidation and sulfidation with subsequent intergranular melting, was readily visible in the near-surface microstructure. A liquid eutectic mixture containing primarily iron, oxygen, and sulfur formed during this hot corrosion attack on the steel... The severe corrosion and subsequent erosion of Samples 1 and 2 are a very unusual event. No clear explanation for the source of the sulfur has been identified.
