Steel, copper, and aluminum are among the very highest possible conductors of heat. Additionally, hardened concrete conductivity is also high. The
higher the volume of conductor, in this case steel, the faster it wicks away the heat, and the more heat it wicks away.
In the WTCs, the steel core columns and the exterior columns contained massive amounts of steel. And the steel available for "sinking" included the
steel in the entire length of the columns. It is unthinkable that even an efficient hydrocarbon fire without supplemental oxygen could heat the steel
using even the maximum amounts of available fuel even burning highly efficiently over the maximum duration of possible time between the time of the
crash and the buildings' destruction.
Given what is known about the efficiency of the fire, its duration, and temperature, it is impossible that these columns could have sustained enough
heat to weaken them enough to cause them to fail.
This factor alone renders the official explanation unfeasible.
