| Summary | Proponents claim that the Twin Towers were brought down by pre-planted explosives rather than by the impact of hijacked airliners and subsequent fires. They argue the official explanation is false and that the collapse pattern indicates a controlled demolition. Evidence and expert investigations, including NIST's final report, conclude the collapses were caused by the aircraft impacts and fires, not explosives. |
| Origin | Emerged in the immediate aftermath of the September 11, 2001 attacks, gaining traction in the following years through online forums and documentaries. |

| Evidence / consensus | NIST's investigation and numerous engineering analyses confirm that the aircraft impacts severed columns, dislodged fireproofing, and the resulting fires weakened the steel structure, leading to progressive collapse. No evidence of explosives has been found. |
