This is NIST's final report on WTC7 is based on the August 21 2008 NIST WTC7 Report (Draft for Public Comment) (click for video and transcripts)


A additional technical briefing was given on [August 26 2008 NIST Technical Briefing August 26 2008] . (click for video and transcripts)


It is the last report released by the Federal Building and Fire Safety Investigation of the World Trade Center Disaster


"The extensive three-year scientific and technical building and fire safety investigation found that the fires on multiple floors in WTC 7, which were uncontrolled but otherwise similar to fires experienced in other tall buildings, caused an extraordinary event. Heating of floor beams and girders caused a critical support column to fail, initiating a fire-induced progressive collapse that brought the building down." - NIST WTC7 Report Press Release
