Search and rescue officials say debris consistent with a plane crash has been located in the waters of Hudson Bay Thursday morning, and there is no sign of the pilot.

One person was on board the Cessna 208 when it left Sault Ste. Marie, Ont., Wednesday on a training flight. It was expected to fly north and then return to Sault Ste. Marie half an hour later.

David Elias, a public affairs officer with the Royal Canadian Air Force, says the Joint Rescue Coordination Centre in Trenton, Ont., began co-ordinating a search that evening at about 5 p.m. ET after the plane's emergency beacon was activated 1,200 kilometres north of Sault Ste. Marie.

Two Hercules aircraft, one from Trenton, one from Winnipeg, participated in the search.

Debris was located at about 7 a.m. Thursday in an area about 500 kilometres east of Churchill, Man., 200 kilometres from Fort Severn, Ont.

β€œIt appears highly unlikely anyone would have survived this situation,” says Elias.

The RCAF says the pilot was out of communication during the flight.

A spokesperson for the owner β€” Edmonton-based Morningstar Air Express β€” says it was an unscheduled flight.

Nunavut RCMP, the Transportation Safety Board and the Nunavut Coroner's Office are investigating.
