Widerøe Flight 933 was operating a scheduled flight between Mehamn and Tromsø on a chilly day in November 1982. The aircraft, a de Havilland Canada DHC-6 Twin Otter, was carrying 12 passengers and 3 crew members when it encountered progressively worsening weather conditions over the Barents Sea. Reports indicate that the plane lost contact with air traffic control due to poor visibility caused by fog and snow. Despite efforts to navigate, the aircraft tragically crashed into the sea near Gamvik, Norway. Rescue operations were initiated immediately; however, all 15 individuals aboard were declared deceased. The wreckage was located several days later and investigations were launched to determine the cause of the accident.The crash prompted a thorough investigation by aviation authorities, including assessing wider implications for flight safety regulations, especially for smaller regional aircraft operating in harsh Arctic conditions. The incident highlighted the significance of advanced meteorological data and the need for improved navigational aids to better assist pilots in challenging environments. Further, it raised awareness surrounding the risks of aviation in remote and severe weather locations, prompting reviews of operational protocols among regional airlines, especially in Norway's high-latitude air travel.
