As we pause to honor neighbors who lost their lives on Sept. 11, 2001, we also revisit some of the people who walked away from the rubble that day.

These survivors relive the terror, the heartbreak and the grim details that have remained with them, and share how the events of a single day have shaped their lives. The special section "That day forward: Our survivors of 9/11" will appear Sunday, Sept. 11.
