Former NIST Employee Speaks Out, Says Building 7 Investigation Bogus, Govt ‘Denied Evidence’

A former employee of the National Institute of Standards and Technology (NIST) has stepped forward and criticized the government agency for ignoring the scientific errors found in its report on the collapse of World Trade Center Building 7 (WTC 7) during the September 11, 2001, attacks. Peter Ketcham, who spent almost fifteen years working at NIST, described how the flawed investigation methods were significantly different from the normal standards used by NIST, in a letter to the editor of the respected Europhysics News magazine. Ketcham’s letter was published in the November 2016 issue and comes just months after the magazine’s August 2016 report examining the Building 7 collapse in detail, which has been downloaded over 350,000 times according to the website.

Peter Ketcham was a contributor to numerous scientific papers during his 14 years as a part of the High Performance Systems and Services Division and later the Mathematical and Computational Sciences Division. Ketcham wrote that he felt compelled to speak out about the NIST WTC 7 investigation after reading the report for the first time in August 2016 and comparing the results with the conventional criticism from other professionals. The NIST report on WTC 7 was published in August 2008, more than 6 years after the attacks, and it concludes that the building collapsed after structural failure due to fires caused by damage from debris when the Twin Towers collapsed earlier in the day.

The root problem with the WTC Building 7 report is that NIST could not perform a definitive study under common standards of the National Fire Protection Association (NFPA) because it lacked the physical evidence. Most of the structural steel was removed and melted down beginning within days after September 11, and some beams were stolen as reported by Telegraph. NIST only had access to about 150 smaller pieces of steel, called coupons, cut from the whole sections of structural steel beams.
