As we recently passed the 18th anniversary of one of America’s greatest tragedies on September 11, 2001, the University of Alaska Fairbanks released a report on the destruction of the 47-story World Trade Center Building 7, which collapsed into its footprint, falling more than 100 feet at the rate of gravity (‘free-fall’=no obstruction of gravity) for a third of its seven-second collapse. According to the National Institute of Standards and Technology (NIST), an agency of the U.S. Department of Commerce, the official cause for the collapse was normal office fires. Yet fire alone has never brought down a skyscraper before 9/11.
Officials from NIST, after claiming that they found no evidence for explosives, admitted that they did not even look for such evidence. They have since refused to consider the evidence when confronted with it. Many independent researchers have studied the collapse of WTC 7 and assembled a body of evidence that raises questions about the validity of NIST’s conclusions.
In the June 2018 issue of WestView News, an editorial stated that the Lawyers Committee for 9/11 Inquiry (LC) had presented their evidence in a 52-page report to the US Attorney General in NYC, demanding the re-opening of an investigation into 9/11 by presenting the evidence to a grand jury. This week, the Lawyers Committee is filing a Federal Complaint against United States Attorney Geoffrey Berman for the Southern District of New York, William P. Barr, Attorney General of the United States and the Department of Justice for Mandamus Relief and Disclosure of Grand Jury Records.
According to the AE911Truth.org website, more than 3,150 Architects & Engineers and 22,787 members of the general public have already signed a petition to urge Congress to re-open the investigation.
With funding provided by Architects & Engineers for 9/11 Truth, Inc., a 501(c)(3) nonprofit organization whose purpose is to conduct research and educate the public about the World Trade Center building collapses on 9/11, they partnered with the University of Alaska Fairbanks (UAF) in releasing the draft report of a four-year computer modeling study of WTC 7’s collapse conducted by researchers in the university’s Department of Civil and Environmental Engineering, College of Engineering and Mines (CEM), Institute of Northern Engineering (INE), with J. Leroy Hulsey, Ph.D., P.E., S.E., as lead author.
The principal conclusion of the study is that fire did not cause the collapse of WTC 7.
This conclusion is based upon a number of findings from different analyses. Together, the report offers the opinion that fires could not have caused weakening or displacement of structural members capable of initiating any of the hypothetical local failures alleged to have triggered the total collapse of the building. The conclusion is that the collapse of WTC 7 was comprehensive involving failure of all columns in the building nearly simultaneously, and not a progressive collapse of columns throughout the building in a sequential failure.
The release of the draft report begins a two-month period during which the public is invited to submit comments. The final report will be published later this year. University of Alaska Fairbanks has published it online.
