On August 12, 2005, more than 12,000 pages of oral histories from 503 FDNY firefighters, paramedics, and emergency medical technicians were made public after The New York Times sued the City of New York for their release in response to the Bloomberg administration’s decision to withhold the…
The following is a compilation of documented eyewitness accounts of molten metal at the World Trade Center. Reports from Direct Eyewitnesses Leslie Robertson, structural engineer for the design of the World Trade Center “[T]hey pulled out the big block of concrete and there was…
Abstract: On September 11, 2001, the world witnessed the total collapse of three large steel-framed high-rises. Since then, scientists and engineers have been working to understand why and how these unprecedented structural failures occurred. Note: This article has received more than one million views since its…
Abstract: Although the events of that tragic day happened 14 years ago, there remain nagging questions of why the 47 storey WTC 7 steel framed structure collapsed, when it was NOT hit by an airplane. We will review the official rationale of how the collapse…
Abstract: This article points out the benefits of employing a performance based analysis approach for ascertaining the likelihood that travelling fires in an office building could induce a localized failure that might trigger its collapse. The case study chosen is Building 7 of the World…

A “normal office fire” cannot cause a fireproofed steel frame to “vanish” in an instant. Incendiaries and explosives can. Symmetrically razing a steel-framed skyscraper in mere seconds, though, requires such extraordinary demolition skills that only a handful companies in the world will even attempt it.
NIST’s fairy tales about these two contributing factors to the collapse — the trusses and a diesel fire — were clearly as ill-founded as the story about the non-existent 10-story gouge.
