-The Bering plane, carrying nine passengers and one pilot, was possibly affected by adverse weather and visibility problems, according to the Nome Volunteer Fire Department.

-Before the plane was reported missing, the Nome Volunteer Fire Department said the pilot had told Anchorage Air Traffic Control that “he intended to enter a holding pattern while waiting for the runway to be cleared.” The U.S. Coast Guard in Alaska said the plane was 12 miles offshore while flying from Unalakleet to Nome when its position was lost, according to USA Today.

-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 (about 19 kilometers) offshore, according to news agency AP.

-The Nome Volunteer Fire Department said in a statement on social media that ground crews were searching across the coast, from Nome to Topkok. “Due to weather and visibility, we are limited on air search at the current time,” it said. People were told not to form their own search parties because the weather was too dangerous.

-According to the National Institute of Occupational Safety and Health, a disproportionate number of air taxi and commuter plane accidents occur in Alaska compared to other U.S. states. Alaska is known for its mountainous terrain and challenging weather. Many Alaskan villages are not connected by roads, meaning small planes are generally used to transport people and goods.
