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.

The commuter flight that crashed on Alaska sea ice last week was part of the workhorse network of short-hop flights that people in the vast state rely on for routine.

The bodies of all 10 people who were killed when a regional airline flight crashed off the coast of western Alaska have been recovered and identified, authorities said Saturday.
