Yes but silly engineer LARED. Fibers,paper,wood etc burns below the temperature of kerosene.Let us refer to no. 5 shall we?
5) "Since the jet fuel fire was brief, and the building still stood, we know that the composite floor slab survived and continued to function as designed (until the buildings were demolished one or two hours later). After the jet fuel fire was over, burning desks, books, plastic, carpets, etc, contributed to the fire. So now we have a typical office fire. The fact that the trusses received some advanced heating will be of little consequence. After some minutes the fires would have been indistinguishable from a typical office fire, and we know that the truss-slab combination will survive such fires, because they did so in the 1975."
