On September 11, 2001, the three worst structural failures in modern history took place when World Trade Center Buildings 1, 2, and 7 suffered complete and rapid destruction.

In the aftermath of the tragedy, most members of the architecture and engineering community, as well as the general public, assumed that the buildings’ destruction had occurred as a result of the airplane impacts and fires. This view was reinforced by subsequent federal investigations, culminating in FEMA’s 2002 Building Performance Study and in the 2005 and 2008 reports by the National Institute of Standards and Technology (NIST).

Since 9/11, however, independent researchers around the world have assembled a large body of evidence that overwhelmingly refutes the notion that airplane impacts and fires caused the destruction of the Twin Towers and WTC 7. This body of evidence, most of which FEMA and NIST omitted from their reports, instead supports the troubling conclusion that all three skyscrapers were destroyed in a process known as “controlled demolition,” where explosives and/or other devices are used to bring down a building.



  1. Rapid onset of destruction,
  2. Constant acceleration at or near free-fall through what should have been the path of greatest resistance,
  3. Numerous eyewitness accounts of explosions including 118 FDNY personnel,
  4. Lateral ejection of multi-ton steel framing members distances of 600 feet at more than 60 mph,
  5. Mid-air pulverization of 90,000 tons of concrete, and large volumes of expanding pyroclastic-like dust clouds,
  6. Isolated explosive ejections 20 to 60 stories below the “crush zone,”
  7. Total destruction and dismemberment of all three buildings, with 220 floors each an acre in size missing from the Twin Towers’ debris pile,
  8. Several tons of molten steel/iron found in the debris piles,
  9. Evidence of thermite incendiaries on steel beams,
  10. Nanothermite composites and iron microspheres found in WTC dust samples.
