news:fUhMg.20531$SZ3.2811@dukeread04... Who said melt? Fire softens steel. It was a damn big building, the fire wasn't everywhere. wrote in message ups.com... | You've seen the photos of the survivors standing in the impact holes on | the side of the tower begging for help. How could they do that if the | temperatures were hot enough to 'melt steel'? | 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. -- "Anybody who deliberately propagandizes with lies should be held up to scorn and ridicule" - Al Franken |
