Default Re: Active Thermitic Material Discovered in Dust from the 9/11 World Trade Center

Another interesting aside with regards the towers,
concrete when heated with an oxygen and acetylene flame explodes quite violently, as an engineer i have witnessed and indeed caused this when using burning equipment in close proximity to concrete, and whats more in almost completely pulverises when it does so.

Kindest regards dave caster
