A little more Pentagon detail

I'm seeing more damage now to the Pentagon, but, if you don't know the construction of the Pentagon, it may be misleading. The building is really five concentric buildings (E ring to innermost A ring) separated by small courtyards and a larger one in the middle. You can see interior structure of at least one side of the five sides of the pentagon forming the outermost ring, near the heliport, but as far as I can tell, the inner wall of the E ring hasn't gone down. The other side of the building looks fine.
