It’s been a point of controversy for more than a decade. Now, researchers from the University of Alaska Fairbanks are weighing in.
World Trade Center Building 7 was not struck by a plane, but collapsed hours after the twin towers on Sept. 11, 2001. A draft report released this week by researchers at UAF suggests that the fall was not a result of fires, despite the findings of the National Institute for Standards and Technology, an agency of the U.S. Department of Commerce, in 2008.
The study was paid for by a group called Architects and Engineers for 9/11 Truth. The nonprofit is said to represent over 3,000 architects and engineers who have signed a petition calling on Congress to launch a new investigation into the destruction of the towers.
Dr. Leroy Hulsey, a civil engineering professor at UAF, led the four-year study. According to the Institute of Northern Engineering’s website, the objective was to examine the structural response of WTC 7 to fire loads that may have occurred that day, rule out scenarios that couldn’t have caused its collapse and identify types of failures that may have caused the fall.
The UAF team’s findings contradict those of the 2008 NIST report, which concluded that WTC 7 was the first tall building ever to collapse primarily due to fire.
According to the NIST report, debris from the north WTC tower (WTC 1) ignited fires on at least 10 floors in WTC 7. Fires on some of the lower floors burned out of control. NIST said the automatic sprinkler system on those floors failed, causing the fires to spread.
“The primary and backup water supply to the sprinkler systems for the lower floors relied on the city’s water supply, whose lines were damaged by the collapse of WTC 1 and WTC 2,” a fact-sheet on the NIST investigation said. “These uncontrolled lower-floor fires eventually spread to the northeast part of WTC 7, where the building’s collapse began.”
Despite NIST’s findings, critics of the government’s account have long argued the building fell in a controlled demolition.
“We virtually simulated the building and we looked at that analysis and we also virtually simulated what they did, we couldn’t get it to do what they did,” Hulsey said.

Its all a big big cover up involving the intelligence of the mossad, uk and of course the cia.
That is bull shit. left wing putzs don’t have anything better to do.
