That's the problem I'm having with the story. The smoke coming from the towers gets really black. Notice no flames visible. Smoke was billowing OUT of the building, and not that much O2 was getting in. So the fire was suffocatiing OR the fuel load had been msotly consumed. However, it's not all about fuel. The structure had been damaged at one corner--on one of the buildings. Fifty floors above is lots of weight. And that weight falling straight down--which it didn't (photographs on one site show the entire top of the building at about a 25 degree angle off perpendicular)--yet the report would have us believe the buildings, both of them, pancaked down. One just like the other.

There were no major cross supports in either building. The sturdy parts of the structure were the corners and the core. Assume the buildings DID pancake down. Why did the core pancake with the rest of the building?

Sorry, buddy, but too many questions didn't get asked at the time and too many questions were NOT addressed in the official report. The report reads lots like fantasy or sci-fi to me: First you suspend your disbelief and THEN ya get led where the author wants to take you.
