Peggy Sue Lammon was 31 and employed as a control operator for the Kalamazoo County Sheriff’s Department when she boarded a 1978 single-engine Cessna on July 18, 1992, for a weekend trip to Beaver Island in northern Lake Michigan. She was a passenger with her husband, Tom Lammon, and friends Ray and Cathy Sears. The plane took off from an airport in Battle Creek around 10:30 a.m. and disappeared from radar about noon while preparing to descend, roughly 35 miles from Beaver Island and near the tip of the Leelanau Peninsula.

State and county agencies, the Civil Air Patrol, and the U.S. Coast Guard mounted an extensive search. On August 3 a small aircraft tire and several pieces of fiberglass matching the Cessna’s color washed up near Good Hart; the tire was confirmed to be from an aircraft. No other wreckage or the four occupants were ever found. The trip’s abrupt vanishing over Lake Michigan remains unresolved and deeply painful for the families.

If anyone remembers that flight, sightings over the Leelanau Peninsula on July 18, 1992, or debris that went unreported, please come forward with information.
