Information on the case from local sources, may or may not be correct : John and his wife,┬áJean, were last seen in Utica, Michigan on July 4, 1977. They took off from Macomb Airport at 11:10 a.m. in their green and white two-seater, single-engine Cessna airplane with the Michigan tag number N 50935. A photo of the plane is posted with this case summary.
The couple planned to visit their son in northern Michigan to celebrate Independence Day together. Their destination was Lost Creek Sky Ranch Airport in Luzerne, Michigan. John is a veteran pilot with thirty years' experience.
The Blocks never arrived at the airport and have never been heard from again. They didn't file a flight plan before leaving the Macomb Airport. They would have normally flown over northbound Interstate 75, but the weather that day was poor and John, who had no instruments on his plane and navigated using visual guidelines only, may have mistaken Interstate 69 for Interstate 75 in the Flint, Michigan area, which would have placed them near Lansing, Michigan. A pilot believes he encountered the couple at an airstrip in Charlotte, Michigan, southwest of Lansing; he stated they took off shortly after noon, heading north. They left the airstrip without refueling because the airport was closed.
An extensive search turned up no sign of John or Jean Block or their plane. North central Michigan, where the search was centered, is heavily wooded and the foliAge at the time of disappearance: may have concealed the wreckAge at the time of disappearance: of the plane. The couple has never been found.

A missing person is a person who has disappeared and whose status as alive or dead cannot be confirmed as their location and condition are not known. A person may go missing through a voluntary disappearance, or else due to an accident, crime, death in a location where they cannot be found (such as at sea), or many other reasons. In most parts of the world, a missing person will usually be found quickly. While criminal abductions are some of the most widely reported missing person cases, these account for only 2ľ5% of missing children in Europe.
By contrast, some missing person cases remain unresolved for many years. Laws related to these cases are often complex since, in many jurisdictions, relatives and third parties may not deal with a person's assets until their death is considered proven by law and a formal death certificate issued. The situation, uncertainties, and lack of closure or a funeral resulting when a person goes missing may be extremely painful with long-lasting effects on family and friends.
Several organizations seek to connect, share best practices, and disseminate information and imAge at the time of disappearance: s of missing children to improve the effectiveness of missing children investigations, including the International Commission on Missing Persons, the International Centre for Missing & Exploited Children (ICMEC), as well as national organizations, including the National Center for Missing & Exploited Children in the US, Missing People in the UK, Child Focus in Belgium, and The Smile of the Child in Greece.
