WTC 7 was not as "neat" a design as the Twin Towers.
Besides the core columns for elevators, stairways and such, forming a rectangular core with no visible columns (like the Twin Towers), and the perimeter columns visible to all, it also had visible columns in the rentable space, specifically the columns supporting the East Penthouse.
Surely with all your experience in the Truther movement, you realize this. To refresh your memory:
You don't think that all that space between the inner core (to the right in the top photo and columns 79,80, and 81 went unrented, do you?
I'm amazed that in all these years, no Truther has interviewed anyone who worked in Building 7, or asked for old photos of their workplace, to get an idea of the layout of WTC 7.
