What happened
On April 1, 1999, an aircraft departed from Port Huron, Michigan, at 11:30 EST, with a scheduled destination of Freemont, Ohio. The flight was intended to transport the pilot to a meeting with a client. Based on the flight path expected by the pilot's employer, the route likely would have crossed over Lake St. Clair in Ontario and Lake Erie.
After the pilot failed to arrive, a client contacted the pilot's company at 12:30 EST to inquire about the flight's status. Following the disappearance, an aeronautical notification (ALNOT) was issued at 18:03 EST. A large-scale search and rescue operation involving the U.S. Coast Guard, the Canadian Search and Rescue Center, and the Civil Air Patrol was initiated. This search continued for over a week before being officially suspended on April 10, 1999.
On May 1, 1999, the body of the passenger was located within the Lake St. Clair shipping channel, roughly 6.9 miles east of St. Clair Shores, Michigan. Later, on July 2, 1999, the body of the pilot was recovered from Lake St. Clair. Debris from the aircraft type was found alongside the recovered remains.
Findings
