The Braathens SAFE aircraft was en route from Trondheim Airport, Værnes to Oslo Airport, Fornebu. While passing Røros the Heron started experiencing a rapidly accelerating atmospheric icing which soon was too extensive for the ice protection system to handle. Combined with downdraft, the aircraft lost sufficient lift to stay airborne. The pilots were able to turn around the aircraft, but it hit Hummelfjell at an altitude of 1,350 meters (4,430 ft) above mean sea level.The aircraft's captain was killed in the impact and a passenger died shortly afterwards. Ten people survived the crash, which was the first fatal accident of Braathens SAFE. Amongst the survivors was Rolf Kirkvaag, at the time Norway's most popular radio host. The search and rescue operation was severely hindered by a blizzard and poor visibility. Kirkvaag and another person left the plane after a day and met a rescue party. The investigation concluded that there were neither technical faults with the aircraft nor pilot error, and that it was not possible to predict the weather conditions which caused the icing.. }
