At 5:20 PM, September 11th, 2001, a 47 story steel frame skyscraper in Manhattan underwent a swift, systematic, straight-down collapse. In a matter of
seconds, the immense 600-foot tall structure was transformed into a small pile of rubble lying almost entirely within the building's original
The building is variously known as Building 7, WTC 7, or 7 World Trade Center. Despite its address, it was across the street from the superblock
containing the rest of the World Trade Center, and was of a different architectural style and age than the 6 other WTC buildings.
The cause of the collapse has never been determined. FEMA's Building Performance Study, the only government document that addressed the collapse of
Building 7 in any detail, stated:
The specifics of the fires in WTC 7 and how they caused the building to collapse remain unknown at this time. ... Further research, investigation, and
analyses are needed to resolve this issue.
By the time FEMA's report was published, the remains of Building 7 had been almost entirely destroyed, nearly all of the structural steel having been
expeditiously removed and shipped to blast furnaces overseas. Without the physical evidence of the structural steel, such research, investigation, and
analyses would be impossible.
