1. Demolition explosives leave evidence of their use, just like fingerprints at a crime scene. The “fingerprint”of Thermite (an incendiary explosive which cuts through steel) was conclusively identified in samples from the World Trade Center by Physics Professor Dr. Steven E. Jones. Additional samples from Ground Zero examined by Chemist Kevin Ryan and other scientists also conclusively identified conditions consistent with the use of demolition charges. Documentation of billions of microspheres containing molten metal from the chemical signature of Thermite can be found in the BPAT Report from FEMA; the Report of the United States Geological Survey; and the report of RJ Lee Group (the company hired by the WTC insurance company to conduct an independent private study). Those findings should have led to investigation procedures determined by the National Fire Protection Association:

NFPA very clearly states melted steel or concrete is a sign of exotic accelerants. Therefore, the
debris should have been thoroughly analyzed for exotic accelerants, specifically Thermite.
