I suppose the WTC tower sample from the Appendix C is the one NIST refers to when it says that one of its 3 (out of 170) samples of perimeter columns that showed evidence of heating above 250 degrees C they considered to have experienced its heating in the context of being cooked after the collapse.

Why do you suppose that is a perimeter column? I don't recall seeing it identified as such in the report.

And why do you suppose it was "cooked after the collapse"? The report clearly states that they do not know when the heating and corrosion took place.

Suggestions for Future Research

The severe corrosion and subsequent erosion of Samples 1 and 2 are a very unusual event. No clear explanation for the source of the sulfur has been identified. The rate of corrosion is also unknown. It is possible that this is the result of long-term heating in the ground following the collapse of the buildings. It is also possible that the phenomenon started prior to collapse and accelerated the weakening of the steel structure. A detailed study into the mechanisms of this phenomenon is needed to determine what risk, if any, is presented to existing steel structures exposed to severe and long-burning fires.

Hoffman....isn't he the guy that said conventional explosives were not likely to have been used? I seem to recall he said that he thought it was advanced microwave weapons. Do those create sulfur when activated?
