Just days before Christmas in 1998, Pan Am flight 103 flying from London to New York blew up over Lockerbie, Scotland, killing 270 people — including 190 Americans. Thirty-five victims were Syracuse University students going home for the holidays after studying abroad. It was the most lethal terrorist attack against American civilians until the September 11 attacks of 2001.
