On the morning of September 11th, a new kind of horror shook the world. Terrorists crashed two passenger airliners into the World Trade Center in the worst attack on U.S. soil in the nation's history. But at the same time a new generation of heroes rose up to fight it. This book chronicles not only the devastation of that day, but also the valor and heroism of those who saved thousands of lives.Not one of these photographs has been published before. On top of that, these images offer a vantage point no ordinary photographers could obtain: They were taken by members of the New York City Police Department, uniformed and civilian, who were on the scene moments after the first plane hit and who were behind the scenes during the entire rescue and recovery effort. Many officers took pictures during the course of their duties. Some were inside the lobbies of the World Trade Center before they collapsed. Some were in helicopters hovering near the burning towers. Some were trapped in the dust cloud after the buildings fell. They took pictures of the pandemonium around them, the fear, the effort, the exasperation. This collection portrays the courage of those who rushed into the danger so that others could escape it.
