John Brett Cahill was a devoted husband, father, brother and friend whose humor, curiosity and love of travel left a lasting impact on everyone who knew him. He was killed aboard United Airlines Flight 175 on September 11, 2001.
Today, John’s sister shares his story with a generation that was not yet alive on 9/11, leaving students with three meaningful lessons: make September 11 a day of service, live safely but never in fear and, whenever you see a beautiful sunset, say hello to John.
