Ex-Scientific American writer a 9/11 skeptic

The post on the GOP insider is just below this one.

Maybe it's because he is Canadian. Maybe it's because he is now a professor emiritus.
But why does a man like A.K. Dewdney get the brush-off from U.S. politicians?

Dewdney, a longtime professor of computer science at the University of Western Ontario, has written a slew of popular math books and been a regular contributor to Scientific American. At least one of his books has been re-issued by Springer-Verlag, a well-known publisher of mathematical books.

Then one day Dewdney had the bright idea of testing whether cell phone calls reputedly from jetliners hijacked on 9/11 were a likely possibility.

What he found was that cell phone usability decreased with increasing altitude. But even at lower altitudes, contact was only intermittent.

Obviously, this finding brings into question the official accounts, especially the accounts of Flight 93 over Pennsylvania. In fact, I once saw an internet report that quoted a telephone company spokesperson as expressing puzzlement about the purported high-altitude cell calls, which were made reputedly in addition to the airphone calls made by some passengers.

Dewdney specialized in discrete mathematics and theoretical computer science. In latter years, he focused on computer modeling of biological phenomena.

I think -- but am not positive -- that Dewdney went public with his early cell phone experiment soon before he retired. Dewdney is another example of the "old guy phenomenon," whereby professionals who have retired, and presumably have little to lose professionally, speak out about 9/11 deception.
