The Bering Air flight was traveling from the village of Unalakleet to Nome when it was reported missing at around 4 p.m. local time Thursday, according to the Alaska Department of Public Safety, State Troopers.

The Cessna Caravan left Unalakleet at 2:37 p.m., and officials lost contact with it less than an hour later, according to David Olson, director of operations for Bering Air. The aircraft was 12 miles (19 kilometers) offshore, according to the U.S. Coast Guard.

Rescue crews are in a race against time to find survivors aboard the Bering Air Flight 445 and are working in ‘zero visibility conditions’
