The tragic events of September 11, 2001 sent shockwaves around the globe that are still felt today. Nearly 3,000 people died in the terrorist attacks and thousands more were injured.  On the afternoon of the attacks, three firefighters paused in their rescue work to raise an American flag at Ground Zero in New York City. In the midst of horror and despair, the iconic photo of the men would remind Americans that they were far from beaten. It represented the country's strength, courage, decency, and its hope for the future.
