Summary based on the NamUs case record (MP26307) and 3 other sources
Kenneth Antolino, a 26-year-old from Nantucket, Massachusetts, was last seen on July 18, 1984. He was piloting a Cessna 172 aircraft with another individual, Mark Vannest, and neither has been seen since. They did not file a flight plan before taking off. Their plane disappeared while flying over the area near Nantucket, sparking a significant search effort. Despite efforts by both air and sea, no trace of the plane or its occupants was ever found. Antolino's case remains open, and he is considered missing under mysterious circumstances.

This incident is part of a broader history of missing aircraft in New England, with various small planes vanishing over the Atlantic Ocean, often without a clear explanation. The lack of a flight plan and the absence of any wreckage have made solving this case extremely difficult, leaving Antolino's disappearance an enduring mystery.

His case has been included in databases like NamUs, but despite the passage of time, no new information has surfaced to provide answers for his family or investigators.
