had some illustrations and written descriptions of the underground areas. I remember a picture of a PATH train that was miraculously undamaged in that book.
this account of inspectors who went underground: (from City in the Sky,James Glanz and Eric Lipton, Times Books Henry Holt & Co. 2003) p. 293-294 "Lopez and Pontecorvo...were walking directly toward what had been the north tower. After a few minutes, their flashlights illuminated a solid, rocklike mass where the basement levels of the tower had been. At first, as the flashlights played over the rocky surface behind the columns, the mind simply could not interpret what the eyes saw: the recognizable traces of twenty floors, very much like geologic strata revealed by a road cut, compressed into a ten-foot vertical span. In one place, the steel decks of half a dozen floors protruded like tattered wallpaper, so close together that they were almost touching where they were bent downward at the edge. Nothing between the decks was recognizable except as a rocky, rusty mishmash. In a few places what might have been carbonized, compressed stacks of paper stuck out edgewise like graphite deposits. They could not be removed.
Lopez and Pontecorvo had found where the vanished floors had gone. They had not just fallen straight down. The forces had been so great and the floors so light that they had simply folded up like deflated balloons.
...The immense columns, at least two feet across, made of steel plate four inches thick, had suffered what looked like a compound fracture: the upper sections looked as if they had been kicked, with incalculable fury, about a foot south of the sections they were resting on....the broken columns, resting so precariously on their edges, not only rose up through the rest of the basement but also supported as much as one hundred feet of the north tower's facade that was leaning--at an angle very much like the one in front of them--against the mangled remnants of 6 World Trade Center."
