The 10 people killed in the crash of a Bering Air flight in Western Alaska last week included a group of engineers from the Anchorage area working on a water plant, a teaching mentor from the Mat-Su and four Nome and Unalakleet residents, including the pilot and a school counselor.

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.

The 10 Alaskans killed in the crash near Nome include a mentor to new teachers, a school counselor and two Alaska Native Tribal Health Consortium employees traveling to service a local water plant.
