Faces of Ground Zero: A Tribute to America's Heroes

Omar Rivera
Senior Systems Designer, Port Authority of New York and New Jersey
With one hand on the arm of his co-worker, Donna Enright, and the other on the harness of his guide dog, Salty, Rivera descended 71 floors in Tower No. 1.
"Salty was nervous, but he was very concentrated on his duty. He and Donna were my angels that day. Many people saw what happened, but I heard it. The sound of the walls cracking, pipes popping, people screaming—it still echoes in my ears."
