OK, Hokulele, I'll play.
Let's focus on the west wall of WTC1. Below are two photos. The ground level shot depicts perimeter steel laying in the westside highway. We observe that it is one layer deep. The second photo shows the entire area where we would expect perimeter steel from the west wall of WTC1. Again, it appears that the steel west of WTC1 was mostly one layer deep. The cranes have removed some of the steel from the second photo, but not very much, and certainly not very much from what once was the west wall of WTC1.
Since the steel laying in the Westside highway is one layer deep, it is reasonable to simply count the sections. One large area shows perimeter sections laying out almost perfectly as they stood. This represents about 12 stories, and appears to be about the full width of the tower. Count them. There are some perimeter sections in the Winter Garden. There are a few strewn about closer to the core.
In total, I can account for no more than about 20% of the perimeter sections from the west wall of WTC1, if that. An additional 90 stories of steel wheatchex would be enormous in the supplied picture. It would be the same size as the Westside highway laydown, only 9 stories tall, at least. If tangled, it could be 15-20 stories tall, or more.
People have analogized this problem to the "jar of jelly beans". Actually, it is more like the jelly beans are spread out on the floor. In such a case, the most accurate way to count the jelly beans, is to simply count the jelly beans.
