Who said melt? Fire softens steel. It was a damn big
building, the fire wasn't everywhere.

It appears you only have to cause one floor to drop in that type of building
to bring it down. On the History Channel they have a program called
Engineering Disasters, and in one of the shows they addressed that very
issue. They had actual films of a building that fell during construction
in just the way the WTC fell. After much testing they found that rebar had
been placed 1/2 inch off from where it was supposed to be in the floor. As
the building got taller there was enough weight placed on a lower floor and
it failed. The building went straight down, just like the WTC, killing a
bunch of workers. All this because of some rebar in the wrong place.
