The Grand Hotel in Brighton was packed with Britain's Conservative leadership for their annual conference when a long-delay bomb, planted by the Provisional IRA weeks earlier in a guest room, tore through the building in the early hours. Margaret Thatcher was still awake working on her conference speech in the room next door and escaped with only cuts, but five people died in the rubble and 31 more were injured, some permanently maimed.
The bomber, Patrick Magee, had checked into the hotel under a false name and set the timer so far in advance that he was long gone before it detonated. The IRA's chilling statement afterward noted that Thatcher had been lucky that day, but they would only need to be lucky once. Magee was later caught through forensic evidence left on the bomb casing and convicted for the attack.
