  • Red and gray chips of the world's most sophisticated nano-thermite, or super-thermite, are dispersed throughout the approximately 30,000 tons of dust generated in the demolitions of WTC 1, 2, and 7; so too are maybe 10 tons of tiny iron-rich spheroidal droplets, another signature of super-thermite explosives.
