On September 11, 2001, pilotless airplanes were guided into the World Trade Center by homing beacons. It wasn't a plane that hit the Pentagon, but a missile. U.S. Air Force planes weren't scrambled to intercept the hijacked planes that morning because the White House was behind the events of that tragic day. Incredible? Definitely. Outlandish? Absolutely. But, there are lots of people who believe that at least some parts of these stories are true.

In a special season premiere investigation the fifth estate's Bob McKeown finds that even the most outlandish conspiracy theory may have its basis in a legitimate question. In the course of separating fact from fiction, Bob delves into the labyrinthine and surprising ties between the Bushes and the Bin Ladens. What he finds out may startle you as much as any conspiracy theory.
