This is the ONE thing I don't get. Now, if there WERE in fact things like office supplies, computers, electrical wiring burning and jet fuel did not produce significant heat to melt steel, then where did this heat come from? A burning piece of paper can't melt steel. I doubt burning insulation on wiring could melt steel. Computers, chairs (fabrics), cubicles (don't burn at too high a temp, right?)... them burning can melt steel? Doesn't SOUND right, does it to any of you?
Now, what I would ask next is... IS there an explosive that can melt steel, since people claim this proves they were brought down by explosives? If so, is it hot enough to flash-melt steel, since for example, a steel column would only be exposed to the heat from an explosion for a fraction of a second, right?
well for one thing the steel didnt melt, not before the towers collapsed at least, the fires softened the already dammaged steel structure to a point where they could not hold the weight of the upper part of the building
in demolition linear shaped charges, or cutting charges, like these are used
as the name implies, they dont melt anything, they cut it, they are fast burning and produce a very large blast wave which cuts the steel, resulting in this
BEFORE
AFTER
the melted steel was found weeks and even months after the towers fell, which theorists say is proof of very hot explosives used (thermite for example, even though thermite isnt an explosive, its more like a very hot napalm) however nothign could impart so much heat to the steel that it would still be melted months later (the steel along with the entire tower would have been vaporized by that much heat) so it means there must have been a constant heat source on the steel under the debris
over the course of weeks or months, even a wood fire can impart enough heat to melt steel (given the nice blanket of debris to prevent heat from escaping)
