Two weeks after 9/11, engineers Pablo Lopez and Andrew Pontecorvo are walking in the B2 basement level at the ruins of the World Trade Center, towards where the North Tower stood. They discover a “solid, rocklike mass where the basement levels of the tower had been,” and see “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.” As New York Times reporters James Glanz and Eric Lipton describe, Lopez and Pontecorvo have found “where the vanished floors [of the tower] 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.” Furthermore, they see the massive core columns of the tower, which are over two feet wide and made of four-inch thick steel plate, appearing to have suffered “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.” Lopez remarks, “Can you imagine the force?” [Glanz and Lipton, 2004, pp. 292-293] At some later time, ironworker Danny Doyle, who is also working at Ground Zero, finds that floors of the South Tower have been compressed into a formation like what happened with the North Tower’s. He discovers “a distinct mound of debris set into the pile, about six feet high, with strands of wire and pieces of rebar sticking out. It looked like layers of sediment that had turned into rock and been lifted up on some mountainside.… Here were ten stories of the South Tower, compacted into an area of about six feet.” [Glanz and Lipton, 2004, pp. 310]
