As federal agency declares 'new phenomenon' downed WTC 7, activists cry foul is a terrific example of how if the facts don't fit the official conspiracy theory, a government agency will change or ignore them. The case in this article is that NIST's study ignores the evidence of the presence of Thermite which is used in controlled demolitions.
"Specifically, in Appendix C of its World Trade Center Building Performance Study, FEMA [emphasis added] claimed:
Evidence of a severe high temperature corrosion attack on the steel, including oxidation and sulfidation with subsequent intergranular melting, was readily visible in the near-surface microstructure. A liquid eutectic mixture containing primarily iron, oxygen, and sulfur formed during this hot corrosion attack on the steel... 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.
Yet, no study of the mysterious sulfur or melted steel was included in the NIST report."
What happened to the steel would not occur during a hydrocarbon fire. So NIST ignored it and the pools of molten steel found at the site. Otherwise their official explanation of structural damage and hydrocarbon causing the collapse would not fit all of the evidence.
