On 11 March 1982 , Widerøe Flight 933 crashed into the Barents Sea between Berlevåg Airport and Mehamn Airport , killing all fifteen people on board the Twin Otter . The accident was caused by structural failure in the rudder and vertical stabilizer following severe clear-air turbulence . A conspiracy theory arose concerning a collision with a British Harrier fighter , which resulted in four investigations — none which found any evidence of a collision
