Controlled flight into terrain has been given as the cause of the Royal Air Force Boeing Vertol Chinook crash on the Mull of Kintyre, Scotland, on 2 June 1994. There were no discernible technical faults, says the official RAF report, although investigators had no flight-data recorder or cockpit-voice recorder to aid them. All 29 on board died when the helicopter hit the rocky promontory in poor visibility.
