Military grade nano thermite. Oddly enough both wtc and the only military base that has thermite ..their security was run by the lesser known Bush brothers. It's small orangish red particulates were found in both air and debris samples in large quantities at the time. It also explains liquified metal pouring out of wtc towers pooling in sub floors and the fire that burned after the slurry walls caved in and did so completely submerged underwater Not typical demo in any way.
