The trade name for this product is “Thermate.”
Girder from the WTC, note the neat diagonal cut
There is a science to placing the charges in such a way that the building falls inward. It requires a great deal of expertise to keep a tall building from toppling over sideways.
Many scientists and engineers have looked at the way the WTC towers fell and remarked that it had the appearance of controlled demolition. The buildings collapsed symmetrically, and fell straight down. The speed of the fall indicated that the buildings
