I can read, which is why I understand his response, and why it is correct. You guys don't seem to understand that there is a reason the style of the support structures used in all three buildings was unusual. It was very susceptible to this type of failure and you only need to reach about half of the melting point of a material before it starts to soften. Mind you that is in Kelvin, so even at room temperature you are pretty far along that graph, just about any fire can get steel or iron red hot. The seemingly neat inward collapse was a result of the same unusual construction. The supports were at the outside and were drawn inward as the center of each floor collapsed.
