Despite having received official instructions to stay put after the 8:46 a.m. crash next door, Rescorla told Morgan Stanley staffers to follow his evacuation plan, and he sent them two by two, as they had practiced, down the many flights of stairs. His decision and his preparation made all the difference. Although 13 employees -- including Rescorla -- perished, more than 2,500 employees left the tower alive. That's where the word "miracle" comes in. It's also where the word "hero" comes in... A fuzzy photo of Rescorla speaking into the bullhorn exists online. He was last seen on the 10th floor -- heading upstairs.
