Most of the links on the forums lead back to two credible sources. After reading them I formed these opinions.
The Dr. Steven Jones' (a BYU Physics Professor) paper
http://www.physics.byu.edu/research/energy/htm7.html
was well written, and interesting. He used good sources, video and photos, to back them up. He met every standard that I would expect for an argumentative paper. I was able to reach him for comment, but did e-mail him.
The Morgan Reynold's essay
http://www.lewrockwell.com/reynolds/reynolds12.html
was not quite this same caliber. First, his status as a former government economist is irrelevant to the argument since it adds nothing to his expertise. Second, I tried to follow up on his sources and they frequently led me to amazon.com. If I want to check on his sources I have to buy his book, I went to the library and local book store and neither had it. I could order it, but will keep trying a way to read it for free. I am not saying that Mr. Reynolds argument is poorly written or ineffective; I am saying that I, personally, will not accept it unless I can verify it.
With the Eagar/Musso paper
http://www.tms.org/pubs/journals/JOM/0112/Eagar/Eagar-0112.html#authors
(which the Steven Jones' paper is trying to rebut), on the one hand, you have a professor of engineering and metallurgy teaming up with another physics professor to argue in favor of fire-induced collapse, on the other you have a physics professor (Jones) arguing in favor of controlled demolition. An easily referenced, clear and logical debate between two experts. It is interesting to read them both, and refreshing.
After reading both, and keep in mind I am not a professor of any of the disciplines mentioned (including economics), I am not persuaded by either to change my view on what happened. These are not the only sources sited by the CT crowd, but they are the ones with the most verifiable data. Please, check them out for yourselves.
