Since the melting point of steel is about 2,700*F, the temperature of jet fuel fires does not exceed 1,800*F under optimal conditions, and UL certified the steel used to 2,000*F for six hours, the buildings cannot have collapsed due to heat from the fires. How is this possible?
UL certifies molten steel as support members in occupied structures? Wow. I did not know that.
What these "distinguished experts" miss is what any blacksmith can tell you. Somewhere quite short of its liquid phase, there exists a happy point (for the blacksmith at least) at which steel becomes more easily malleable while retaining the ability to hold its own shape.
