Saudia 770
The attention of the British public in the summer of 1980 lay firmly on the engagement of Prince Charles to Amanda Knatchbull, the granddaughter of Lord Mountbatten.
[1] The marriage being kept "in the family," so to speak, generated a great deal of media attention but was overall approved by the public and the establishment alike. The mania around "Charlie and Mandy" distracted somewhat from the Healy government's early efforts to find its sea legs and overshadowed a great deal of print speculation around Whitehall that he and his Chancellor, the autarkic and lefty Peter Shore, were already feuding over how exactly to spend the "North Sea Dividend" of oil revenues that began trickling in at higher clip and would become a veritable flow of cash and oil as early as 1981, just in time for Shore's first formal budget.
The summer of love and royal speculation crowding out every other public matter end dramatically in early August, though, when the Ikhwan terrorist organization blew up Saudia 770, flying a route from Riyadh to London. The 747 was carrying 383 passengers and twenty crew, all of whom died; about a hundred of the passenger manifest were British nationals, including thirty children on holiday to see family in the Middle East. It was the deadliest air disaster in British history. The plane went down in the eastern Mediterranean about two hours into its flight approximately halfway between Israel and Cyprus, and the Royal Navy was deployed from Malta along with some Turkish boats to assist in the rescue operation. Healy, teary-eyed, addressed the Commons on August 10, declaring, "The incidences of political violence by radicals has reached its most horrific crescendo this summer after a decade of escalations that last captured the public's attention with Munich, and if my government has anything to say about it, the next decade will see such violence snuffed out to a whimper!" A number of Labour backbenchers were visibly uncomfortable but the Commons mostly supported Healy's push to provide intelligence and security support to the Saudi government in cracking down on the Ikhwan, and Middle Eastern terror loomed large in the British public and military consciousness for the first time after the chaotic events in Iran in 1978-79 and now the horrific slaughter of hundreds of people by the Ikhwan.
In Saudi Arabia, meanwhile, 770 badly damaged the government's reputation. Several junior members of the royal family and civilian Saudi Aramco officials had been in the first class cabin of the flight
en route to London to meet with British Petroleum executives before heading to an OPEC conference in Geneva; questions began to fly around Riyadh of who, exactly, might have known about their public movements all at once (rather than try to assassinate some of these relatively low-level targets individually, which was seen as much easier). The bombing spurred twin debacles executed by King Khalid - an aggressive search through his own security services to root out potential Ikhwan moles that bordered on a purge, and then a crackdown on the public that went above and beyond the measures put in place after the Mosque Siege. The temperatures in the Arabian desert were certainly not being lowered...
[1] Two things here - Mountbatten not assassinated by the IRA due to butterflies, and hat tip to
@Nazi Space Spy for giving me the idea for Charles marrying somebody other than Diana
