Recovery crews worked amid freezing temperatures and slushy sea ice Friday to recover the remaining victims aboard a regional airline flight that crashed off the coast of western Alaska.

Just hours after finding 10 people dead in western Alaska from one of the deadliest plane crashes in the state in 25 years, authorities are racing to recover their remains and the wreckage of the small commuter plane from unstable sea ice before expected high winds and snow.

Planes carry transponders that transmit their real-time location. The Alaska plane stopped sharing that data on Thursday.
