FEMA report confirms molten steel found at WTC 7
FEMA confirms that molten steel was found at the WTC7 site.

"It is much more difficult to tell if melting has occured in the grain boundary regions in this steel as was observed in the A36 steel in the WTC 7."
Under the "Suggestions for Future Research" you find this...
"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."
Thermite and thermate will give the result found under the rubble. It keeps on eroding and giving off heat for a very long time. Plus, needs no oxygen to do that.
