On September 3rd, the Architects & Engineers for 911 Truth, in conjunction with the University Of Alaska Fairbanks (UAF), released a draft report of a four-year study into the downing of WTC 7, entitled “A Structural Reevaluation of the Collapse of World Trade Center 7.” The final report will be published later this year, after a two-month consultation period, whereby the public can submit comments. We would encourage everyone to download the report, which can be found at the following link:
However we would like to draw your attention to a number of key points within this report, contained within the executive summary, which we quote ad-verbatim:
“According to the National Institute of Standards and Technology (NIST) — an agency of the U.S. Department of Commerce that investigated the three building failures on 9/11 — the collapse of WTC 7 was the first known instance of the total collapse of a tall building primarily due to fires.
However, 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. The objective of this study, therefore, was threefold: (1) Examine the structural response of WTC 7 to fire loads that may have occurred on September 11, 2001; (2) Rule out scenarios that could not have caused the observed collapse; and (3) Identify types of failures and their locations that may have caused the total collapse to occur as observed.
The UAF research team utilized three approaches for examining the structural response of WTC 7 to the conditions that may have occurred on September 11, 2001. First, we simulated the local structural response to fire loading that may have occurred below Floor 13, where most of the fires in WTC 7 are reported to have occurred. Second, we supplemented our own simulation by examining the collapse initiation hypothesis developed by NIST. We also reviewed the collapse initiation hypotheses advanced by private engineering firms whose studies were commissioned as part of litigation related to the collapse of WTC 7. Third, we simulated a number of scenarios within the overall structural system in order to determine what types of local failures and their locations may have caused the total collapse to occur as observed.
The principal conclusion of our study is that fire did not cause the collapse of WTC 7 on 9/11, contrary to the conclusions of NIST and private engineering firms that studied the collapse. This conclusion is based upon a number of findings from our different analyses.
Together, they show 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, nor could any local failures, even if they had occurred, have triggered a sequence of failures that would have resulted in the observed total collapse.
The secondary conclusion of our study is that the collapse of WTC 7 was a global failure involving the near-simultaneous failure of every column in the building. This conclusion is based primarily upon the finding that the simultaneous failure of all core columns over 8 stories followed 1.3 seconds later by the simultaneous failure of all exterior columns over 8 stories produces almost exactly the behavior observed in videos of the collapse, whereas no other sequence of failures that we simulated produced the observed behavior. We cannot completely rule out the possibility that an alternative scenario may have caused the observed collapse; however, the near-simultaneous failure of every column is the only scenario we identified that was capable of producing the observed behavior.”
From our perspective and having personally witnessed the events of 911 unfolding in real time, albeit from a London office, I can recall in the immediate aftermath of these horrific events, thinking that the official narrative regarding WTC7 made absolutely no sense. How could a building fall as a result of office fires? In that regard WTC7, from my perspective, has always been the Achilles heel of this entire investigation and its findings.
We can only hope that this report will be the catalyst to finally reveal the truth of events surrounding 911, including WTC1 and WTC2 and who was ultimately responsible. In many senses, revealing the truth about 911, will prove to be a watershed moment in American history and why there have been vigorous attempts to hide the facts. We extend our gratitude to the Architects & Engineers for 9/11 Truth for their sterling work over many years and dogged persistence in the face of hostility at times. We have long since passed the time when we should be calling 911 a conspiracy theory. The facts speak for themselves,
