Yes, zig. But even you agree that really doesn't answer what happened to building 7.
I've been accustomed to seeing fires in most building collapsing a corner of the structure. But I don't believe I've ever seen a building like 7 collapse the way it did from a fire.

Because of the footprint and the type of structure that 7 was the only likely cause of the fall that would make some sense structurally that I could come up with (along with a few structural engineers in my office) is that the underground support structure was compromised by the collapse. Hence the straight down fall into itself. Lower Manhattan, particularly that area is basically suspended over tons of open space for the tubes. I had them actually write something up for me. I will see if I can find it.
