ya just gotta watch this video of a very good experimental demonstration that the official version is as false as a wooden nickel...and NIST knows it!

[after watching the video...read this: Steven Jones mentioned experiments that he had done with thermate on steel previously at 911blogger:
"I (with colleagues) have done the experiment with thermite + sulfur (often called "thermate") acting on a piece of WTC steel. In fact, I did the experiment with BBC filming it! Then we looked at the steel, including use of electron microscopy, and found the same characteristic corrosion as found by Barnett et al. in WTC 7 steel.
OTOH, I know of no expt done to test whether gypsum and heat would have this effect -- I would be VERY surprised, as the sulfur in gypsum is not elemental Sulfur, but is bound as a sulfate (very difficult to reduce to suflur.) We should do the latter experiment to rule out such nonsense. If you can provide direct quotes from the BBC program on this point, it may prove useful in a research note on the subject.
Meanwhile, for BBC to neglect our experimental replication of the observed corrosion, using thermite + sulfur, is rather remarkable in itself, seeing that they filmed one of our experiments, as I distinctly recall."
Gypsum is calcium sulfate dihydrate, not elemental sulfur. To break gypsum down into elemental sulfur requires a rather involved industrial process.
Now I wonder why NIST, which investigated WTC7 for about 6 years, could not bring themselves to do such a simple experiment?]:vroam:
