Ok, so after closing this window I went and looked up more information out of my own curiosity, yeah I know I said I was done but I had to present my findings.
I did some research and I think the wikipedia article probably sums up everything quite nicely, the sources for the article are of course listed at the bottom of the page. http://en.wikipedia.org/wiki/Collapse_of...ade_Center
Here are some points for you to look at Mozzy.
1. The WTC towers were designed to withstand the impact of a plane crashing into it's side, in case some pilot lost his way in the fog, but it was designed for what was the largest plane at the time. Know what that was? The Boeing 707-320 and in comparison the impact that plane would have made is less than one seventh of the impact that was made on 9/11, though this still didn't bring the buildings down.
2. The columns to support the building were all placed at the perimeter and the core leaving a large amount of empty space in between, this is probably why the plane penetrated so deep into the building.
3. Jet fuel can burn at 800-1500 degrees but steel loses half it's strength at 1202 degrees.
4. The impact completely blew off a great deal of the fire proofing around the steel.
5. The stairwells were determined to be improperly shielded.
6. Due to the placement of the columns once the strength of the core columns began to wane all of the weight was transfered to the perimeter columns, using the system you spoke of before Mozzy. But the perimeter columns were also weakened by the fires placing a lot of pressure on the exterior walls. Of course with the perimeter now failing the pressure was redistributed back to the core and boom...the tower comes down.
7. You were correct, though I didn't argue this point, they fell symmetrically.
To be continued, time to go home...
...Continued
8. Some speculate that even without the impact of the plane and with the fire proofing still intact the building still would have collapsed with a fire of that magnitude.
9. The 7th building, which you question the collapse of, had several diesel fuel tanks stored on several levels and pipe lines connecting them.
Those are the only two points I really want to add at this time.
