About President's commission on aviation security and terrorism

Pan American Flight 103 blew up over Lockerbie, Scotland, on December 21, 1988. 243 passengers, 16 crew members, and 11 people on the ground were killed by the explosion. It was the second most disastrous passenger airline explosion up to that time. By the next day, experts found enough evidence to declare the explosion to have been caused by sabotage. Within days intelligence sources reported an anonymous telephone call to the United States embassy in Helsinki, Finland, on December 5, 1988, warned of possible sabotage on the flight.
