                Debunking the 9/11

            Myths: Special Report -

           The World Trade Center



              by Popular Mechanics Editors


            Following the September 11, 2001 terrorist
           attacks against the United States, a wave of
            conspiracy theories swept the nation. The
           destruction of the Twin Towers in New York
          City was an inside job, they claimed, the work
            of the federal government, and "truthers"
           filled the internet with supposed proof of the
                         vast conspiracy.


               It was in this climate that Popular
          Mechanics took on the task of debunking the
             myths about the 9/11 attacks. Our first
           report appeared as the cover story for the
          March 2005 issue. The reporting grew into a
