In perfect conditions the maximum temperature that can be reached by hydrocarbons such as jet fuel burning in air is 1520° F (825° C). When the World Trade Center collapsed the deeply buried fires would have been deprived of oxygen and their temperatures would have significantly decreased.
Why was the temperature at the core of “the pile” nearly 500° F hotter than the maximum burning temperature of jet fuel a full seven days after the collapses? There were no infernos in either of the twin towers before they collapsed, so what caused the hot spots deep in the wreckage?
