Carol - the fires were caused by the damage sustained. As for me showing evidence of a building collapse, perhaps it would be more appropriate for you to show us an example of a building falling sideways as you are suggesting?

Tuskegee is a red herring. We all know that the government lies and has always, and will always, conduct nefarious projects in secret. As issue with the WTC is how they could have pulled it off on such a large scale. The involvement would have required thousands, and someone would have talked - as the whistle blower in Tuskegee did.

Sure there are holes in the "official" report, but there are hundreds more in the conspiracy theories which cannot apply logic to prove their points. Gravity does not work the way you say.
