FRANKFORT — Two men who were on board an aircraft that went missing at about 8 p.m. Sunday near Frankfort have been named.
Emanuel Z. Manos, 53, of Monroe, and Randal S. Dippold, 65, of Perry, were flying the Beechcraft Bonanza when it fell off the radar about five miles west of Frankfort over Lake Michigan, according to information from the Benzie County Sheriff's Office.
Authorities do not know which man was flying the aircraft when it went down.
About 70 volunteers were expected to search the Lake Michigan shoreline along with the county's Community Emergency Response Team (CERT) near Frankfort today and Thursday to look for any signs of the crash.
Boats and helicopters from the U.S. Coast Guard, Michigan State Police and the U.S. Department of Homeland Security have been searching for the plane since late Sunday, covering about 1,400 square miles.
No signs of a crash have yet been spotted and the search has turned into a recovery mission, according to the sheriff's office.
Personnel working a Minneapolis control tower contacted the Coast Guard on Sunday after losing contact with the plane, which had reported engine trouble.
A flight plan shows the Bonanza took off from Ontonagon near Houghton in the Upper Peninsula and was headed for Monroe. When the aircraft reported engine problems, it was redirected to the Frankfort Dow Memorial Airport.
Benzie County Sheriff Ted Schendel had said indications were that the aircraft had likely gone down in the lake about four miles offshore.
The Lake Ann area was searched Monday after a father reported his daughter heard what sounded like a plane crash.
Anyone with information about the crash should contact the Benzie County Sheriff at 231-882-4484.
