May 1974
London’s Heathrow Airport was blasted by a 100lb terror bomb which was planted in the three-storey car park beside Terminal One on Sunday morning (19-5-74). It wrecked scores of cars, but amazingly only four people were hurt. The explosion came eighteen minutes after a man with an Irish accent had telephoned a warning to a London Press agency. The chaos which followed virtually closed the airport for three hours. Police warned later that the blast – thought to be the work of the Irish Republican Army Provisionals – could signal the start of a new campaign of terror in England.
