I have always dismissed the 9-11 Truthers as a bunch of kooks on two grounds. First, their flagship claim -- that the WTC towers were intentionally demolished -- doesn't stand up to scrutiny. (Frankly, it doesn't even pass the laugh test, but I don't want to get into that.) And second, I have a general prejudice against grand conspiracy theories because I just don't believe that people are very good at keeping secrets, and large groups of people are particularly bad at it. A chain is only as strong as its weakest link, and the more people are involved and more time goes by, the more likely that someone will spill the beans.
But now I just watched this video of David Ray Griffin, professor emeritus of Philosophy of Religion and Theology at the Clarement School of Theology, by the CBC (Canadian Broadcasting Company) explaining how the official story about the cell phone calls from the flights hijacked on 9/11/01 couldn't possibly be true. He certainly doesn't sound like a kook, and the facts that he bases his conclusions on are all easily verified by third parties. They also pass my basic bullshit-o-meter. In particular, I believe it is true on both theoretical grounds and from firsthand experience that it is not possible to make a cell phone call from an airplane at altitude.
According to Griffin, the *official* story has quietly changed: the FBI now says that there were no (successful) calls from flight 93 or 77, which is plausible. But the problem with that is that it undermines the basis for the official story that the hijackers attacked with knives and box cutters. If there were no calls, there is no way to know what weapons were used, or indeed if any weapons were used at all, because those calls were the *only* information we had about how the attacks were carried out.
That the official story could change in such a fundamental way and not draw even passing notice from the mainstream media is very disturbing, particularly in light of the manifest failures and subsequent self-flagellation from the media about the handling of the buildup to the war in Iraq.
I am really beginning to think that there could have been a 9/11 conspiracy, not because the secret could be kept, but because the official story is so appealing -- it's such a powerful mythology -- that when inevitably the truth starts to leak no one cares.
