William Langewiesche� American Ground: Unbuilding the World Trade Center

I started going with some of the core people like Peter Rinaldi and Pablo Lopez on their underground explorations. They were surveying the situation down in the ruins. It was truly dangerous stuff�not only because of what you breathe, but because nobody knew what was down there, and things were collapsing all over the place. I was with them on those runs, and after a while they understood that I was with them there in a big way. Where they went, I went.
