CNN and the BCC reporting it live before it happened? Well, they still don't have the answer for that one. |

and yes, rosie o'donnell you fat pig, steel does and can melt. but it'll lose it's integrity long before that happens.

Steel melts at about 2,750 degrees Fahrenheit—but it loses strength at temperatures as low as 400 F. When temperatures break 1000 degrees F, steel loses nearly 50 percent of its strength. It is unknown what temperatures were reached inside WTC7, but fires in the building raged for seven hours before the collapse.

I'd like to see some statistical odds of that happening to building 7, RBE. Has to be real small.
Yes, zig. But even you agree that really doesn't answer what happened to building 7.
I've been accustomed to seeing fires in most building collapsing a corner of the structure. But I don't believe I've ever seen a building like 7 collapse the way it did from a fire.
