Norseman IV (2481) aircraft, which had taken flight from Ketchikan in Alaska to return three American USO (United Service Organizations) concert performers to Annette Island, encountered a sudden snow squall while attempting to land near the Annette Island base; the four air crewmen and three USO civilians perished when the aircraft crashed into the sea, six miles north-west of Annette Island, near Warburton Island.
