A de Havilland Canada DHC-6 Twin Otter 100 transport plane, operated by the Royal Norwegian Air Force, was destroyed when it crashed near Harstad, Norway. All 14 passengers and three crew members were killed.
The airplane operated on a flight from Bardufoss (BDU) to Bodø (BOO) via Skagen (SKN). At Bardufoss the pilot was advised to cut out Skagen because of bad weather, and instead continue directly to Bodø. However, the pilot decided to head to Skagen, taking off at 15:18.
At 15:43 the airplane struck Lille Tussen Mountain (800 m) on Grytøya Island, some 20 metres below the summit. The plane had drifted somewhat to the north and should have passed over the south-east end of the island on a west/south westerly course.
It appeared that the pilot had insufficient rest following a party the night before. Also, the blood alcohol concentration was 1-1,5 permille.
