Fire needs oxygen, from air.
Where is the air when a 40 foot pile of rubble is squishing the fuel (diesel from the generator tanks would be the dominant fuel...I'd surmise, then we have computers, carpet, books, clothes, coffee cups, pencils, paper, potted plants, tissue, plastics and any other combustible material inside the building)...all of which needed lots and lots of air to sustain conventional incineration. How did this fire get fed the air needed to sustain a 5 days incineration. Why on earth did the firefighters say that there were "oven" like conditions at the trade centers six weeks after 9/11. And guessed that it was 1500 degrees. He pointed out “bright bright reddish orange” steel six weeks later (as shown in the video below at about 2:50).

If a 40 ft pile of rubble is all of what's left of a 610 foot building, it's going to starve air in less than 5 days. Much less. Wrong? If so, how I am wrong?
How did firefighters say "beams were being pulled up and burst into flames...kind of spooky." What flames? How is that even possible?
Also, if the rubble height is 40 ft, as indicated by aftermath photos, you have roughly .85-.9 ft per floor. Since the concrete decks are 5.5" thick alone, and some some thicker, that is a tight fit for the rest of the 25,700 tons of structural steel and the remainder of the building contents. Wrong?
Again, how did the fire stay get fed and stay fed with air with a compacted rubble heap such as this? Was their forced convection from below? If so, tell me more about this...
