HA! Creep rates! Assume that the steel did fail. Assume that the pancake theory is true. Documents on buildings 1 and 2 tell you that they each contained 47 interior columns, and 250-odd exterior columns. The interior and exterior columns were connected by steel supports, and used to create each floor. The floor beams were bolted to the columns, and the heat from the jet-fuel caused the bolts/nuts and the surrounding area to "weaken", not melt, so that those bolts were warped. With no support in the floor whatsoever, the floors pancaked onto eachother in a "domino effect"

Thats the long and short of it.

Except for one minor detail. Those 47 columns in the centers of WTC1 and WTC2. They would not have been affected. Look at PBS digital depictions, as well as those of the History Channel. Notice that they leave the interior columns in place, because their collapse cannot be explained by jet fuel, nor by the impact itself. The floors only could have pancaked between the interior and exterior columns, leaving both erect. I'd be glad to discuss this with anyone.
