A small commuter plane that crashed in western Alaska on its way to the hub community of Nome was located Friday on sea ice, and all 10 people on board were dead, authorities said. The crash was one of the deadliest in the state in the last 25 years. Rescuers were searching the aircraft’s last known location by helicopter when the wreckage was spotted, said Mike Salerno, a spokesperson for the US Coast Guard. Two rescue swimmers were lowered to investigate.

The Bering Air single-engine turboprop plane was traveling from Unalakleet on Thursday afternoon with nine passengers and a pilot, Alaska’s Department of Public Safety said. It was operating at its maximum passenger capacity, according to the airline’s description of the plane.
