Call me crazy. I blame terrorists.

Who is A. K. Dewdney? He's an adjunct professor of biology at the University of Western Ontario, and he has pieced together the truth about what happened on 9/11. You may be familiar with the official version: "To account for the events of Sept. 11, 2001, the Bush White House has produced a scenario involving Arab hijackers flying large aircraft into American landmarks," writes the eminent Ontario academic. "We, like millions of other 9/11 skeptics, have found this explanation to be inconsistent with the facts of the matter."

Instead, he argues, a mid-air plane switch took place on three of the jets. "The passengers of one of the flights died in an aerial explosion over Shanksville, Pa.," he writes, "and the remaining passengers (and aircraft) were disposed of in the Atlantic Ocean." Most of us swallowed "the Bush-Cheney scenario" because we were unaware that, when two planes are less than half a kilometre apart, they appear as a single blip on the radar screen. Thus, the covert switch. Instead of crashing into the World Trade Center and the Pentagon, the flights were diverted by FBI agents on board to Harrisburg, Pa., where the passengers from all three planes were herded onto UA Flight 175 and flown on to Cleveland Hopkins and their deaths. By then, unmanned Predator drones had been substituted for the passenger jets and directed into their high-profile targets. The original planes and their passengers were finished off over the Atlantic.

The really amusing irony here is that even in the remote case that any of the conspiracy theories are valid, the conspiracy theorists are such a bunch of flaming nutballs, they provide an almost impeccable cover for the would-be dastards.
