To all the Internet engineers and pseudo-physicists here who must know that engaging me in a technical debate that would prove only that I am neither an engineer nor a physicist, I will instead post the findings of Steve Dutch, Professor of Natural and Applied Sciences at the University of Wisconsin-Green Bay. I hope his work causes the Nutters here to question the 9/11 CT Movement's "facts" as vociforously as they do the NIST study. Regretably I doubt they have the rationality to do so. My thanks to Slackjaw for the link. 
Nutty 9-11 Physics
"A few months ago I agreed to be on a truther talk show (I'll try almost anything once. Almost.) and the commercial breaks were a revelation. There were endless spiels for crank medical remedies and nutritional supplements, investment schemes that ranged from shady to crazy, newsletters for conspiracy cults, and wacko theories on how to avoid taxes. One former truther who became disillusioned said he would no longer help the movement sell T-shirts and DVD's. It's a lot more than just T-shirts and DVD's. Look at the Web sites, the newsletters, listen to the talk shows and look at who's bankrolling them and advertising on them. Truther sites are to conspiracy thinkers what televangelists are to lonely Christians: a place to send money to buy a feeling of participation and fulfillment." - Steve Dutch
