Rick Rescorla is credited with saving all but 6 of his 2700 employees during the 9/11 attacks by directing people down the stairs of the South Tower using a bullhorn and encouraging them by singing Cornish songs. Rick Rescorla, a former British military officer, served as the head of security for Morgan Stanley in the South Tower of the World Trade Center. The 1993 terrorist attack on the complex deeply impacted him, reinforcing concerns he had already raised about the building's security vulnerabilities before the bombing. Believing the World Trade Center would face another attack, Rescorla consistently drilled Morgan Stanley employees in emergency evacuations, a practice that ultimately saved their lives on September 11, 2001. On the morning of the attacks, Rescorla grabbed his megaphone and instructed nearly 3,000 Morgan Stanley workers to follow the evacuation plan he had instilled in them. As they descended the stairwell, shaken by the second plane's impact, he used his megaphone not only to guide them but also to soothe their nerves, singing Cornish and Welsh songs to keep them calm. During the evacuation, Rescorla called his wife, telling her, “Stop crying. I have to get these people out safely. If something happens to me, know that I've never been happier. You made my life.” After successfully evacuating most of the employees, someone suggested his job was done, urging him to leave. He responded, "You hear those screams? There are more people up there. I have to help get them out." He was last seen heading back up the stairwell, around the 10th floor, before the South Tower collapsed. His body was never recovered. Out of the 2,700 Morgan Stanley employees, only six sadly perished. Rescorla is credited with saving thousands of lives that day.
