Steel will fail when the temperature gets high enough, and jet fuel burns hot enough that you cannot use steel in turbine engines because it would melt, even though the internal parts are air-cooled. You don't need to "cut" when the columns will fail in shear along diagonal lines. And you can't call the government out for lies when you don't even know the subject matter.
We can go over it again. The adiabatic flame temperature of kerosene is 2093 C (3801 F). (In rocket engines it can reach ~3,400 C at high pressure.) The melting point of iron is 1538 C (2800 F). At 600 C, the strength of structural steel is 30% of its strength at room temperature. If you still believe you understand the circumstances, you shouldn't be on this Q board. This is basic science that you can look up.
That was the day I woke up. I was in welding class at city college cutting some steel with an oxy-acetylene torch.
I just so happened to be cutting a piece of 2-inch thick steel I-beam at the time the two planes hit the twin towers.
The government tried telling me that steel can be cut with jet fuel.

Steel melts at 2500F. Jet fuel burns from 800F to1500F.
Oxy-acetylene flame gets anywhere from 5600F to 6300F.
If you still believe that the fire from jet fuel brought those twin towers down to the ground, then you shouldn't be on this Q board.
This is basic common sense stuff.
