Authorities have located a pilot's log book and jet fuel in a debris field on Lake Superior, about a mile offshore from Duluth's Brighton Beach, after reports that a single-engine plane crashed this morning.
The U.S. Coast Guard reported that the items were among the debris found in an area about 250 yards in length.
According to the Duluth Fire Department, the control tower at the Duluth International Airport reported at 11:30 a.m. that a plane had gone missing. The Coast Guard said it received a report from the tower of "a single engine white and maroon airplane spiraling down with a loss of communications approximately 7 nautical miles east of Duluth."
Another caller reported possibly hearing a crash on Lake Superior, officials said. The plane reportedly had a single occupant, whose identity has not yet been released.
The Duluth police and fire departments, the Coast Guard and the St. Louis County Rescue Squad responded to the vicinity of Brighton Beach and starting searching the lake in foggy conditions.
At about 12:15 p.m., search crews identified the debris field. Emergency personnel remain on the scene and on the water; no further information was immediately available.
