The search in northwest Alaska intensified Friday for a plane that disappeared with 10 people on board, officials there say. Bering Air Flight 445 — a Cessna 208B Grand Caravan — was carrying nine passengers and a pilot from Unalakleet to Nome when it went missing on Thursday afternoon,

Radar at the time showed that at about 3:18 p.m. Thursday, “this aircraft experienced some type of event, which caused them to experience a rapid loss in elevation and a rapid loss in speed,” Coast Guard Lt. Cmdr. Benjamin McIntyre-Coble said during a media briefing Friday. “What that event is I can’t speculate to.”
