A single-engine plane flying over water in Alaska just south of the Arctic Circle with 10 people on board experienced a sudden loss in elevation and speed just before its signal was lost, authorities said Friday. At least one of the searchers scouring miles of frozen tundra and flying over icy seas also had found “some sort of item of interest” on Friday afternoon, U.S. Coast Guard Lt. Benjamin McIntyre-Coble said, without providing specifics.
