Griffin takes aim at official 9/11 conspiracy theory

It wasn't until a colleague sent Dr. David Ray Griffin an e-mail with Paul Thompson's timeline—an exact, minute-by-minute accounting of the events of Sept. 11 based entirely on mainstream media accounts—that he changed his mind. "The most glaring anomaly," Griffin now says, "was that none of the hijacked planes were intercepted, even though all of them would have been, had standard procedure been followed."

According to Gen. Ralph Eberhart, head of North American Aerospace Defense Command (NORAD), from the time the FAA senses something is wrong, it takes about a minute to contact NORAD, after which NORAD, Eberhart says, can scramble fighter jets "within a matter of minutes to anywhere in the United States." So what happened on that morning?
