About the NIST World Trade Center Investigation
GENESIS OF THIS INVESTIGATION
On August 21, 2002, the National Institute of Standards and Technology (NIST) announced its building and fire safety investigation of the World Trade Center (WTC) disaster.1 This WTC Investigation was then conducted under the authority of the National Construction Safety Team (NCST) Act, which was signed into law on October 1, 2002. A copy of the Public Law is included in AppendixA.
The goals of the investigation of the WTC disaster were:
To investigate the building construction, the materials used, and the technical conditions that contributed to the outcome of the WTC disaster after terrorists flew large jet-fuel laden commercial airliners into the WTC towers.
To serve as the basis for:
Improvements in the way buildings are designed, constructed, maintained, and used;
Improved tools and guidance for industry and safety officials;
Recommended revisions to current codes, standards, and practices; and
Improved public safety
The specific objectives were:
Determine why and how WTC 1 and WTC 2 collapsed following the initial impacts of the aircraft and why and how WTC 7 collapsed;
Determine why the injuries and fatalities were so high or low depending on location, including all technical aspects of fire protection, occupant behavior, evacuation, and emergency response;
Determine what procedures and practices were used in the design, construction, operation, and maintenance of WTC 1, 2, and 7; and
Identify, as specifically as possible, areas in current building and fire codes, standards, and practices that warrant revision...
...NIST found no corroborating evidence for alternative hypotheses suggesting that the WTC towers were brought down by controlled demolition using explosives planted prior to September 11, 2001. NIST also did not find any evidence that missiles were fired at or hit the towers. Instead, photographs and videos from several angles clearly showed that the collapse initiated at the fire and impact floors and that the collapse progressed from the initiating floors downward, until the dust clouds obscured the view...

“U.L.’s testing procedures helped make that possible”
"When I was fired by Underwriters Laboratories (UL) for publicly questioning the company’s testing related to the World Trade Center (WTC), and its role in the WTC investigation being conducted by the National Institute of Standards and Technology (NIST), UL claimed that there was “no evidence” that any company had tested the WTC steel components.
Of course, that was a lie. The company had already admitted that it was responsible for the fire resistance testing related to the WTC buildings, in an April 2002 letter to the editor of the New York Times. Below is that letter. UL had also certified the fireproofing material and had consulted with the Port Authority of New York and New Jersey throughout the life of the buildings. The author of the letter to the editor, UL’s manager of its Fire Protection division, Tom Chapin, wrote in defense of ASTM E119, the standard test UL had used to ensure fire resistance of the buildings. The NYC code, which UL’s CEO had confirmed to me was used to guide the testing, required two hours of fire resistance for the steel columns and 3 hours of fire resistance for floor assemblies. One of the buildings fell in 56 minutes..."http://ultruth.wordpress.com/2011/03/19/u-l-s-testing-procedures-helped-make-...
