And Mediguy... Here's something new..... Entire floors were "
Mechanical floors" where electrics, wiring, machines, havac, and everything else required to run a city of fifty thousand people were stored.
God only knows what was stored in these floors.
You keep thinking of the towers as "buildings". They were so much more than that. More people worked in the WTC than live in my home town here. It was so big it had it's own power sub station.
