Kevin Ryan makes it clear that the fires should have had a negligible effect on the WTC towers, as he made clear in his letter to NIST.

In post 29, shaman_ argued that Mr. Ryan bases that belief on the belief that the steel didn't reach temperatures over 250C and that that view is mistaken.

This is true. But as I pointed out in post 44, it's understandable that Ryan was misled in this regard, shaman's feelings on the matter notwithstanding. Mr. Ryan explains in his letter to Frank Gayle of NIST:
"Your comments suggest that the steel was probably exposed to temperatures of only about 500F (250C), which is what one might expect from a thermodynamic analysis of the situation."

In post 45, shaman_ argued that "he is focusing on one piece of research and ignoring the rest." In post 47, I countered that he was focusing on Frank Gayle's interim NIST report. If anyone was at fault for allegedly not noticing that the steel had gotten hotter then 250C, it was NIST's. They're the ones who were on the scene, not Kevin Ryan.

shaman_ didn't respond to this assertion.
