Original Note:
Jet fuel burns at a temperature of 800 to 2500 degrees F. https://firesafetysupport.com/what-temperature-does-jet-fuel-burn/ Structural steel loses 60% of its strength at temperatures above 1000 degrees F. https://www.engineeringtoolbox.com/metal-temperature-strength-d_1353.html As the building's weight is constant, the same load is supported by less load carrying capacity, leading to failure.
