The Killer Fires or Core Meltdown Theory

  • columns were 100% steel, not reinforced concrete.
  • core structures were 87 X 137 feet, not 30 X 50 feet.
  • structural steel melts at ~1510º C, not 800º.

We heard numerous references to the unimaginably intense infernos, with comparisons to the heat output of nuclear power plants.

The BBC quoted "structural engineer" Chris Wise:

It was the fire that killed the buildings. There's nothing on earth that could survive those temperatures with that amount of fuel burning. The columns would have melted, the floors would have melted and eventually they would have collapsed one on top of each other.

Many experts embraced the steel-melting-fires idea
