September 11th Terrorist Attacks
Firefighters work beneath the destroyed mullions, the vertical struts, of the World Trade Center’s twin towers after a terrorist attack in New York Tuesday, Sept. 11, 2001. As workers cleared some of the rubble, new crews of firefighters and rescue workers charged into the devastation with shovels, pickaxes and flashlights to look for bodies or survivors.
