On September 11, 2001, World Trade Center Building 7 (WTC 7) collapsed without being struck by any aircraft. This building, part of the seven-building World Trade Center complex in New York City, was not near the Twin Towers and remained untouched by the planes that hit the North and South towers.
The U.S. National Institute of Standards and Technology (NIST) attributes WTC 7’s collapse to fires ignited on multiple floors by debris from the collapsing Twin Towers. According to NIST, heat from these fires caused steel support beams to expand, triggering a cascade of structural failures that led to the building’s complete collapse.
However, alternative explanations persist. Civil engineering professor Robert Korol and colleagues from Architects & Engineers for 9/11 Truth (AE911Truth) have published research indicating that WTC 7’s collapse involved controlled demolition using thermite. Their analysis notes that debris was scattered up to 370 meters from the site, and critical structural steel would require temperatures exceeding 660°C to fail—conditions achievable through thermite-based explosives.
Donald Trump publicly questioned the official narrative on September 11, 2001, stating: “It wasn’t architectural defect. The World Trade Center was always known as a very very strong building… I just can’t imagine anything being able to go through that wall.”
