By allowing the attacks to happen -- or in the case of the most extreme theories, by organising them under a false flag" -- the military-industrial complex in America, headed by Dick Cheney and his neocon supporters in the Project for a New American Century, guaranteed that America would stay at war and that profits would stay high. The authors of Revealed, both radical journalists, have subjected the official version of what happened to intense scrutiny and found huge gaps. Recalling that most of what we know about what happened on the planes comes from alleged calls made by passengers on mobile phones, they point out that most experts say that, for technical reasons, this contact would have been impossible to make. They highlight the absence of Mayday distress signals, the failure to find the black-box flight recorders for the WTC aircraft...the failure to carry out a full engineering investigation into why the towers collapsed so fast and the failure to scramble military aircraft to intercept the hijacked aircraft. Even more intriguing is the role of Hani Hanjour, the pilot of Flight 77 that hit the Pentagon. Anyone who examines the route taken by Hanjour will see that it required a complex maneuver by an experienced pilot. Yet in 2001, when Hanjour tried to fly down the Hudson air corridor in a light aircraft, his trainer was so unnerved that he denied him a second run. You don't have to be a conspiracy nut to see that the official account published by the 9/11 Commission is full of gaps.
