Fifteen people are killed when Widerøe Flight 933 crashes into the Barents Sea near Gamvik, Norway.

Widerøe Flight 933, also known as the Mehamn Accident, was the crash of a de Havilland Canada DHC-6 Twin Otter operated by Norwegian airline Widerøe. The Twin Otter crashed into the Barents Sea off Gamvik, Norway on 11 March 1982 at 13:27, killing all 15 people on board. The results of the four official investigations were that the accident was caused by structural failure of the vertical stabilizer during clear-air turbulence. A mechanical fault in the elevator control system caused the pilots to lose control of pitch; and either a series of stalls or a high-speed gust of wind caused the aircraft to lose altitude without the ability of the crew to counteract, resulting in the failure of the vertical stabilizer.

The Barents Sea is a marginal sea of the Arctic Ocean, located off the northern coasts of Norway and Russia and divided between Norwegian and Russian territorial waters. It was known earlier among Russians as the Northern Sea, Pomorsky Sea or Murman Sea ; the current name of the sea is after the historical Dutch navigator Willem Barentsz.
