for an unbiased look at the issue, check out http://www.cbc.ca/sunday/
but you have to check it out before sunday, i am too sick to find the permalink, and i am sure they update their webpage.
the cbc talked to people from both sides, including Jim Meigs, Editor-in-Chief of Popular Mechanics who published "9/11 Myths: Why Conspiracy Theories Can't Stand Up To The Facts". This interview is particularly interesting. As is the Lee Hamilton interview. He was co-chair of the 9/11 commission, and wrote a book and stuff.
