9/11 conspiracy theories

9/11 conspiracy theories are conspiracy theories that attribute the planning and execution of the September 11, 2001, attacks against the United States to parties other than, or in addition to, al-Qaeda including that there was advance knowledge of the attacks among high-level government officials. Government investigations and independent reviews have found no evidence for the theories. Proponents of these theories claim there are inconsistencies in the official conclusions, or evidence that was either ignored or overlooked.
