I am posting this one only in the interest of discourse. I have looked at the NIST report on the WTC collapse. The conclusions and the analysis that led to them seem credible to me. Fantastic claims, as made in the document below, demand fantastic proof, and I don't see fantastic proof here.
I will, however, relate a conversation I had with a guy who developed some of the first finite-element analysis code able to run on small computers. He mentioned he had walked around the WTC and had noticed the building's framed tube design, with lateral loads supported by the exterior members. He said it was at that point he decided he really didn't want to be in that building any longer than necessary, and walked out.
This was years before 9-11-01.

Architects & Structural Engineers Submit Evidence of Controlled Demolition, Disputing NIST's Theory of 9/11 Building Collapses
Houston, TX, September 9, 2008 -- The conclusions from a recent report (8/21/08) submitted by NIST, the National Institute of Standards and Technology regarding World Trade Center-7's destruction on September 11, 2001 is contrary to all historical, visual, and physical evidence, according to an independent worldwide organization composed of more than 470 engineers and architects. WTC-7 was a 47-story skyscraper located more than a football field away from the North Tower and was not hit by any airplane, yet completely collapsed hours after the Twin Towers fell in a similar manner.
“Our engineers are preparing a technical response to the many problems in NIST's report,” states architect Richard Gage, AIA, “but one critical element is simple: In the history of steel-framed structures, no high-rise building has ever collapsed from fire before, even when other fires were hotter, more widespread, and lasted far longer…and yet this is the explanation NIST expects us to accept.”
Kamal Obeid, a licensed Structural Engineer, concurs. “Nothing we are being told by NIST justifies how the destruction of WTC-7 and the Twin Towers was so fast, so symmetrical, and produced so much pulverized concrete. Fire in steel-framed high-rises simply cannot cause it to collapse like a house of cards. Let's remember the Twin Tower fires only encompassed the upper floors, and burned for less than two hours. And yet, what we witnessed were three total collapses at near free-fall speed.”
Adds Structural Engineer Ron Brookman, “Many people say that 9/11 changed everything, but it didn't change the laws of physics.”
It appears there is one explanation that these structural engineers, architects, and physicists steadfastly agree upon: Explosive Controlled Demolition.
“There is an abundance of evidence which NIST refuses to look at or even account for that clearly points to controlled demolition as the source that destroyed these buildings,” states Dr. Steven Jones, a physicist and retired professor at Brigham Young University who examined the pulverized dust at Ground Zero. “Chemical analysis found traces of thermite, a compound long used to melt steel. It is disturbing that NIST refuses to acknowledge the presence of thermite in the debris or the pools of molten metal that numerous rescue workers found “flowing like lava” in the rubble. The extremely high temperatures (4,000 + degrees Fahrenheit) associated with this molten metal is confirmed by NASA sensors, and could never have been caused by jet fuel fires, which burn at 800-1,200 degrees Fahrenhe it. Steel melts around 2,800 degrees Fahrenheit. Thermite is designed to melt steel, jet fuel cannot.”
More evidence pointing to a Thermite Controlled Demolition: Iron-rich microspheres discovered by the US Geological Survey heavily dispersed throughout the disaster site are only produced by thermite under explosive conditions. More than one hundred rescue workers testified they heard explosions just prior to the collapse of the Twin Towers.
Family members of 9/11 victims asked many of these same questions at NIST's recent technical briefing. Over 470 architects and engineers are lending their voices and considerable expertise to those 9/11 families and many others now demanding a true independent investigation with subpoena power to find out what really happened on September 11, 2001.
Richard Gage, Dr. Stephen Jones, Ron Brookman, and Kamal Obeid are available for individual or group interviews. Dr. Jones and Richard Gage have appeared on dozens of interviews worldwide, including the BBC.
