This guy is an engineer. Allow him to explain.

I can tell you that he is absolutely correct. If I had my settings wrong, I could seriously weaken and even deform steel, but it would not cut or weld, depending on what I was doing with it. Mind you, it can be crushed and manipulated in many ways. Steel is not the be all, end all of metals. I could put a sheet of it in a one-ton brake and it would bend like butter in the sun. How many tons do you suppose those top floors weighed?
" I answered this question many years ago and it has been referenced in many different web sites and reports. There has been one misrepresentation that has come from that. Many sites refer to the difference in the melting point of steel and the burning temperature of jet fuel as proof that the World Trade Center could not have fallen from the aircraft fires. What those authors fail to note is that while steel melts at around 1,370°C (2500°F) it begins to lose its strength at a much lower temperature. The steel structure of the World Trade Center would not have to melt in order for the buildings to lose their structural integrity. Steel can be soft at 538°C (1,000°F) well below the burning temperature of jet fuel."
I presume you are talking about this point here. Well if that is the case this person does not mention the limitations of jet fuel which burns at about 200-300 degrees C in open air conditions (similar to WTC conditions) well below the temperature require to "severely compromise" steel.
