"One piece Dr. Astaneh-Asl saw was a charred horizontal I-beam from 7 World Trade Center, a 47-story skyscraper that collapsed from fire eight hours after the attacks. The beam, so named because its cross-section looks like a capital I, had clearly endured searing temperatures. Parts of the flat top of the I, once five-eighths of an inch thick, had vaporized.
That in no way indicates the presence of molten steel, . Where did you get that idea? Remember, Dr. Astaneh-Asl has said that fire, not explosives nor incendiaries, was responsible for the collapse of the WTC buildings.
Charred does not mean, melted.
That confirms what I have been saying all along and that in regards fire weakening and buckling the steel structure. There are means to determine whether the steel buckled due to high impact temperatures or due to impact damage. First of all, you will see cracks develop due to impacts and I have repeadedly said that buckling was an indication that fire was weakening the steel structure of the WTC buildings and I have said so on many occasions.
I have also mentioned on a number of occasions that we throw hardened steel into ovens in order to form them into complexed shapes.
