The September 11 attacks were an "inside jobs"

The most well-known conspiracy theory concerning the terrorist attacks on the US on September 11, 2001, relates to the collapse of World Trade Centre Tower 7. It fell later after the collapse of the neighbouring Twin Towers after they were hit by hijacked airliners. The official report into the tragedy cites flaming debris from the burning skyscraper crashing into the 47-floor Tower 7 and sparking fires on several floors. The heat generated brought the tower down, concluded the National Institute of Standards and Technology – making it the first steel skyscraper in the world to collapse because of fire. In November 2016, a group of top engineers from the University of Alaska said “office fires” could not have caused its destruction. Presenting the team’s findings at the Justice In Focus Symposium in New York, leader Dr J Leroy Hulsey revealed: “It is our preliminary conclusions based upon our work to date that fire did not produce the failure at this particular building.” Their verdict stoked theories that the World Trade Centre buildings were brought to the ground by controlled demolition explosions but there is no evidence to support such a theory.
