1. Conspiracies & Theories

2. Controlled Demolitions Theories say the collapses of the North Tower, South Tower, and WTC 7 were caused by explosives found in the building in advance. Many physicists, architects, and engineers argue that the aircraft impacts and fires could not weakened the buildings enough to cause a complete collapse at the speeds that they had happened without additional energy to weaken the structure. Scientists have found thermite and nanothermite in the dust from the collapse of the buildings which proves there had been explosives planted in the buildings prior to the plane crashes. There have many witnesses to the plane crashes that claim they had heard, felt, and experienced explosions in and under the buildings during the attacks.

3. The Pentagon Many people believe it was not a plane that hit the Pentagon but a missile launched by the U.S. Government. Some say the hole made in the Pentagon was too small for Flight 77 to fit into, and there was an exit hole found on the building that only a missile could have made. There also has been no footage or photos of a plane hitting the Pentagon on surrounding security cameras.

4. No Planes Nico Haupt and former chief economist within the Department of Labor under the Bush administration Morgan Reynolds claim there were no planes. They believe the planes of Flight 11 & 175 being largely made of aluminum couldn’t have penetrated the steel frames of the Towers. They believe digital compositing was used to depict planes in videos and that they were really missiles surrounded by holograms to be made to look like planes.

5. Flight 93 Out of the four planes hijacked, Flight 93 was the only plane that did not reach it’s target. The plane landed in a field near Shanksville, Pennsylvania after the passengers revolted. People believe this plane was shot down by a U.S. fighter jet. There were many pieces of the plane found miles away from the crash site, not being consistent with other plane crashes. The main body of the engine was found miles away with heat comparable to what a heat- seeking missile would do to an airliner. Many believe the plane was shot down by the government because the passengers found out about the alleged plot.

6. Hijackers Sixteen of the nineteen hijackers should have never been allowed into the U.S. because there was some thing wrong with their visas, their passports. They should have been stopped at the border, and this would not have happened. Five of the alleged hijackers may have received training at U.S. military facilities. The Defense Department confirmed that three of the hijackers, Mohamed Atta, Abdulaziz al-Omari and Saeed al-Ghamdi have the same names as alumni of American military schools. A Mohamed Atta attended the International Officers School at Maxwell Air Force Base in Alabama; an Abdulaziz al-Omari went to the Aerospace Medical School at Brooks Air Force Base in Texas; and a Saeed al-Ghamdi was at the Defense Language Institute at the Presidio in Monterey, California.
