  skos:definition "The downing of Pan Am Flight 103 by a terrorist bomb over Lockerbie, Scotland, in December 1988 was the worst civil air disaster ever in the United Kingdom. Hijackings of airliners by terrorists occurred throughout the 1970s and 1980s, prompting Pan American World Airways (Pan Am) in 1986 to hire an Israeli consulting firm to review its security system.
