9/11 Truth movement

Adherents of the 9/11 Truth movement are conspiracy theorists who dispute the mainstream account of the September 11 attacks of 2001. The ""truthers"", as they are called, sometimes pejoratively, dispute the commonly accepted account that Al-Qaeda terrorists hijacked four airliners, crashed them into the Pentagon and New York's Twin Towers, whereupon the crashes led to the collapse of the Twin Towers. Truthers primarily focus on what they say are significant inconsistencies in that explanation, suggesting a cover-up and, at the least, complicity by insiders.They analyze evidence from the attacks, discuss different theories about how the attacks happened and call for a new investigation into the attacks. Some of the organizations assert that there is evidence that individuals within the United States government may have been either responsible for or knowingly complicit in the September 11 attacks. Motives suggested by the movement include the use of the attacks as a pretext to start wars in Afghanistan and Iraq and to create opportunities to curtail civil liberties. Support for the movement is negligible from professionals in relevant fields, such as civil and aerospace engineering.
