THE PHYSICAL IMPOSSIBILITY OF A COLLAPSE BY FIRE
Steel will do all kinds of "tricks," but actually melting it requires a basic melting temperature of 2890° F or greater (jet fuel burns at 1800° F maximum). Melting also requires the element of time, sufficient to permit thermal energy buildup and "peak" melting temperature. To obtain the melting temperature for steel - not iron - one needs the external temperature of approximately 2,900 degrees (F) with enough time for the metal to convert from a solid to a liquid. The process can be sped-up, but only with a much higher temperature -- such as Thermite -- approximately 5,400 degrees (F). That's almost twice the needed heat. All the pooled jet fuel in the world won't burn hot enough to produce molten steel - under any conditions. Molten steel was found in the basements under the debris piles of the twin towers and WTC#7.
