AE 9/11 spews pure nonsense. Im sure Gage at least is making big bucks with speaking fees. Start with these:
"What Did and Did not Cause Collapse of WTC Twin Towers in New York" Journal of Engineering Mechanics ASCE, Vol. 134 (2008).
Refutation of controlled demolition theory. Discusses matching of video record with progressive collapse equations, "free-fall" claims, concrete crushing (and how much TNT equivalent would be needed to do that crushing), air pressure & ejection of air, spread of dust cloud.
Debunking 9/11 Debunking:PDF
Clear, concise refutation of David Chandler's WTC 7 "freefall" claims, by "alienentity." Part 1. Part 2. See also his video "WTC7 Collapse."
This is a perfect strawman.
The people who are most likely to say that the Bush government was responsible (organising, training or just looking the other way) now explain why it was no controlled demolition.
That's totally brilliant.
The government is responsible, and they don't even have to deny it, because they had people claiming they did it a certain way. They didn't do it that way, which can be proven. The general gist people get is they didn't do it.
