9/11 Conspiracy Files: The Third Tower

Saturday February 18 at 10 pm ET/PT & Sunday February 19 at 8 pm ET on CBC News Network

9/11 Conspiracy Files: The Third Tower delves into one of mysteries surrounding Sept. 11th, a third tower at the World Trade Centre, which along with the Twin Towers, collapsed on that fateful day. But this skyscraper was never hit by a plane. This 47-story tower fell seven hours after the others and has become the subject of heated speculation and conspiracy theories largely fuelled by the internet. 9/11 was the first global event in the age of the worldwide web and it's being used as a platform for a wide range of conspiracy theories - more than 50 at the last count - that allege that the U.S. government was somehow involved in the attacks on the World Trade Centre and the Pentagon.

Conspiracy theorists like Dylan Avery believe the Third Tower was brought down by a series of controlled explosions. Avery is the 24-year-old documentary maker behind the internet phenomenon Loose Change which has been viewed tens of millions of times on-line. He and his film pull no punches, claiming a government conspiracy was behind the events of 9/11 and the ensuing wars in Iraq and Afghanistan. The mysterious collapse of the third tower is central to his argument. It's an accusation the U.S. Government categorically denies.

After seven years, on Aug. 21, 2008, the official report on the World Trade Centre collapse of Building 7 (the Third Tower) was released. U.S. Federal investigators concluded that fire weakened floor beams and a critical support column leading to the collapse of the third tower. However, that would make the third tower the first and only skyscraper in the world to collapse solely due to fire. 9/11 Conspiracy Files: The Third Tower explores the many questions that continue to fuel conspiracy theorists.

9/11 Conspiracy Files: The Third Tower is directed by Mike Rudin, and produced for the BBC, part of a series investigating and debunking widely held conspiracy theories, while also exploring the inconsistencies and holes in the official accounts.
