First of all, the movie doesn't even touch on HALF of the crap these guys (who have hired a proxy group to register their domain... can't even whois the owner of the site).

But let's just DEBUNK A SINGLE DEBUNKING on their site...

The WTC category, the fire temperature. They're *claim* is that 500 degrees Centigrade (about 900 F) is enough to collapse the WTC. The only problem with that is that structural grade steel used in the WTC retains over 90% of it's load bearing strength until it is COMPLETELY heated to 550 degrees centigrade (1022 F). Those beams and columns were rated to more than three times that heat for the duration of an hour. When the entire mass of structural steel has reached 550 degrees centigrade, the strength of the steel is about 80% that of room temperature. It would take HOURS for that to happen in the WTC. Jet fuel only burns that hot in a PURE OXYGEN ENVIRONMENT. And given that there was PLENTY of ways for the heat to dissipate out of the building and the fact that most of the fuel exploded out of the building during the first few minutes, there is NO POSSIBLE WAY the COLUMNS or GIRDERS got that HOT IN THAT AMOUNT OF TIME. And by the way, the debunker's links don't work and I can find no reference to that person directly given testimony or discussion about the topic.
