The U.S. Coast Guard in Alaska found the wreckage of a small plane atop frozen sea ice on Friday, after the aircraft suddenly lost altitude on Thursday and the crash killed all 10 people on board, officials said.

Rescuers searched Friday for any sign of a plane that went missing while carrying 10 people across Alaska’s Norton Sound south of the Arctic Circle.

Authorities are working to recover the wreckage of a plane crash in western Alaska that killed 10 people while investigators are trying to determine what caused the small commuter aircraft to go down in the icy Bering Sea.
