A recent poll by the respected New York Times revealed that three out of four Americans now suspect the U.S. government of not telling the truth about 9/11. This proportion has shot up from a year ago, when half the population said they did not believe the official story. [The] accepted version of what happened on 9/11 is being challenged by a 90-minute internet movie, [Loose Change, which is] so popular that up to 100 million viewers have watched [it]. Why were no military aircraft scrambled in time to head off the attacks? How could a rookie pilot - as one of the terrorists was - fly a Boeing 757 aircraft so precisely into the Pentagon? The movie's assertions are being explored by a number of commentators in America and Britain. Former Labour Cabinet Minister Michael Meacher ... has said of 9/11: "Never in modern history has an event of such cataclysmic significance been shrouded in such mystery." These words were written in a foreword for Professor David Ray Griffin's bestselling book, The New Pearl Harbour. Griffin ... is emeritus professor at the Claremont School of Theology in California and a respected philosopher. Together, the book and the movie have raised the question: could the attack be a carbon copy of Operation Northwoods, an aborted plan by President Kennedy to stage terror attacks in America and blame them on Communist Cuba as a pretext for a U.S. invasion to overthrow Fidel Castro? Initially ... Professor Griffin dismissed claims the attacks could have been an inside job. It was only a year later ... that the professor was sent a 'timeline' on the day's events based entirely on newspaper and television accounts. It was then that he changed his mind.
