On the evening of December 21, 1988, Pan Am Flight 103 traveling from Frankfurt to New York crashed over Lockerbie, Scotland, after a stopover at London's Heathrow Airport, killing all 243 passengers and 16 crew along with 11 civilians on a residential street.

Following a three-year joint investigation by Dumfries and Galloway Constabulary and the U.S. Federal Bureau of Investigation (FBI), arrest warrants were issued for two Libyan nationals, Abdelbaset Ali Mohamed al-Megrahi and Lamen Khalifa Fhimah.

A Scottish court found Fhimah not guilty, though Megrahi was found guilty and sentenced to life in prison.
