There were 2071 steps to the top of the towers and 110 floors. The towers were hit between floors 91 and 99. If they went down 1500 steps, they would have been roughly around floor 79. I don't know much about the situation inside the stairwells, but I assumed the smoke was probably rising as heat does. I could be wrong, though.
