The staff of the publication Popular Mechanics undertook a comprehensive debunking of the conspiracy theories that emerged in the initial years following the attacks. They began their work around 2005, culminating in a 2006 book, Debunking 9/11 Myths: Why Conspiracy Theories Can't Stand Up to the Facts.
The documentary also features well-known skeptic Michael Shermer, with the now-infamous Alex Jones representing the viewpoint of the 'truthers'.
