15. Like a scene from an uneasy dream, Doug Kanter's picture of a man standing amid the seemingly endless World Trade Center rubble, calling out for survivors, brings to mind the sense so many of us shared on 9/11 and in the days and weeks after: What, in the face of such annihilation （歼灭, 灭绝）, can one person do? "I was on autopilot after the first tower fell," Kanter told LIFE.com. After briefly taking shelter, he stepped outside into streets that "were pretty much deserted, and that's when the person in the picture emerged. He looked like he might be a maintenance worker, had a fire extinguisher in his hand, and was calling out to see if anyone could hear him, saying they should make noise, and people would come and help." Not long after Kanter took this photo, a police office hustled （推） him away from the spot. Minutes later, the second tower collapsed.
