The 9/11 Commission Report, is the official report of the events leading up to the September 11, 2001 terrorist attacks. Adherents of the 9/11 Truth movement however, dispute the mainstream account of the September 11 attacks of 2001. The group disputes the commonly accepted account Al-Qaeda terrorists hijacked four airliners, crashed them into the Pentagon and New York’s Twin Towers, where the crashes led to their collapse. The primary focus is on missed information not adequately explained in the official NIST theory, such as the collapse of 7 World Trade Center. They suggest a cover-up and, at the least, complicity by insiders.
