Conspiracy theories around September 11
The events of September 11 gave rise to many conspiracy theories that contradict the official investigation.

Controlled demolition: Proponents of this theory claim that the Towers of the VTC were destroyed by explosives. However, the National Institute of Standards and Technology (Nist) scientifically refuted this version, explaining the collapse of the weakening of steel structures under the influence of fire.
Pentagon: Some believe that the Pentagon hit a rocket, not a plane. This theory is refuted by the wreckage of the aircraft, onboard sensors and eyewitness testimony.
Flight 93: There is a theory that this aircraft has been shot down. However, the record from the black box clearly indicates the fight of passengers, which led to its fall.
Although these theories exist, they do not have scientific confirmation and are refuted by the results of numerous official investigations.
