KINGSTON, Jamaica — Trailed much of the way by two U.S. fighter jets, a small plane with an unresponsive pilot flew a ghostly 1,700-mile journey down the East Coast on Friday before finally crashing off the coast of Jamaica.

The fate of the pilot and anyone else aboard was not immediately known.

Maj. Basil Jarrett of the Jamaican Defense Force said the plane went down about 14 miles northeast of the northern coastal town of Port Antonio and the military sent two aircraft and a dive team to investigate.

The plane took off at 8:45 a.m. EDT from the Greater Rochester International Airport in New York. Air traffic controllers were last able to contact the pilot of the Socata TBM700, a high performance single-engine turboprop at 10 a.m. EDT.

The pilot, who was not identified, had filed a flight plan with the FAA to fly from Rochester to Naples, Florida.

Fighter jets were scrambled at 11:30 a.m. EDT and followed the plane until it reached Cuban airspace, when they peeled off, said Preston Schlachter, a spokesman for the North American Aerospace Defense Command & US Northern Command. FlightAware, an aviation tracking website, showed the plane over the Caribbean south of Cuba at about 2 p.m. EDT.

It finally came down after flying more than 1,700 miles.

FlightAware identified the plane has owned by a company based at the same address as a real estate firm in Rochester. The firm, Buckingham Properties, is owned by developer Larry Glazer, who is president of the TBM Owners and Pilots Association.

A person who answered the phone at Buckingham Properties declined to comment. Glazer’s son Rick Glazer said: “I don’t have any comment about what’s going on at this time.”
