1. September 11, 2001 - Thanks to the power of the web and live broadcasts on television, the conspiracy theories surrounding the events of 9/11 - when terrorists attacked the World Trade Centre in New York and the Pentagon in Washington - have surpassed those of Roswell and JFK in traction. Despite repeated claims by al-Qaeda that it planned, organised and orchestrated the attacks, several official and unofficial investigations into the collapse of the Twin Towers which concluded that structural failure was responsible and footage of the events themselves, the conspiracy theories continue to grow in strength.
