Ok I thought it was going to be a tight race today... Untill I read this story. This IS the dumbest thing I've seen all day.
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.
Yet, no study of the mysterious sulfur or melted steel was included in the NIST report.
After New York City officials cut off the water main to the tower Sept. 11, 2001, the building's sprinkler system was unable to function, Dr. Sunder said. This allowed fires across 10 floors to burn uncontrolled for nearly seven hours.
The Institute asserts that due to the lack of water supply, an “extraordinary event” occurred, and for the first time ever, steel expanding due to heat from the flames caused columns to separate from structural concrete. Column 79 was the first to fail, according to the report, which brought about a quick succession of failures in adjoining columns.
"Thermal expansion of long-span floor systems" was a critical element in the collapse, said Dr. Sunder. The "kink" seen in the building's penthouse portion in video of the collapse was in-line with the columns which failed first.
"If water had been available, it is likely that sprinklers would have operated and the building may still be here today," he said.
"It looks like they want to wrap-up this investigation and blame [the collapse] on normal office fires," said Gage during counter-conference.
WTC 7's structural system is in "widespread use" in other buildings, he added, insisting that such effects may also be present elsewhere. The Institute's report also includes recommendations for the strengthening of building codes to avoid future thermal expansion-driven collapses.
The collapse of WTC 7 is "no longer a mystery," Dr. Sunder claimed.
The Institute's full report is available at wtc.nist.gov.
Further details from the Architects & Engineers for 9/11 Truth press conference are forthcoming.

9/11 researcher Dr. Steven E. Jones of Brigham Young University, in a newly published paper entitled "Revisiting 9/11/2001 – Applying the Scientific Method," explains the important physical evidence of Thermite (and its analogues such as Thermate) found in the dust of the World Trade Center. This paper discusses the tiny iron-rich spheres, some as large as 1 or 2 mm, which were found in great abundance in the dust from the WTC.
Based on the mass of these iron-rich spheres found in a sample of the dust found in a nearby apartment, Jones estimates (roughly) that about .04 percent of the dust was "iron-rich spherule," which would be "of the order of ten tons." This gives us some idea of how much Thermite (Thermate, etc.) was in the twin towers.
The presence of metallic microspheres implies that these metals were once molten, so that surface tension pulled the droplets into a roughly spherical shape. Then the molten droplets solidified in air, preserving the information that they were once molten in the spherical shape as well as chemical information.
Iron melts at 1538 degrees C, so the presence of these numerous iron-rich spheres implies a very high temperature. Too hot in fact for the fires in the WTC buildings since jet fuel (kerosene), paper and wood furniture – and other office materials – cannot reach the temperatures needed to melt iron or steel. (Remember the wood-burning stove…)
click on C2 sample 1 (from WTC7) you read that the FEMA engineer hired to analyse the steel says that the steel was eroded by EXTREMELY high temperatures, like 1800 f....
he says the steel in sample 1 was sulfidised.. he doesn't explain why it was sulfidised tho...
sulfurised thermite is called thermate...
see C6... he says plainly that he cannot explain the the source of the sulphur, and suggests that it could represent danger to other already exsiting and yet to be built buildings, but the report also states that WT7 is the only building (of its' type) ever known to have collapsed from only fire... the only other two known example were also hit by planes (WTC 1&2)

Yeah, this has been floating around for a while. This is clearly why every particle of debris from the WTC's and the pentagon have been quietly taken out of the country. No one was allowed to do a real investigation. Twenty thousand pounds of explosives weren't smuggled onto those planes... Third worlders living in caves didn't smuggle twenty thousand pounds of explosives into the world trade center... No one has this ability... except for one entity.

Oh I know.. I've been thinking the same thing. Doesn't really matter if the plane goes down in a thousand feet of water.. two years later, that plane will be completely reassembled in some hangar... with scotch tape if necessary. This time? Nope.. nothing. There are just too many first evers for any one bit of this tale to be close to true.
