"The pilot of the Cessna 150 called out an airborne emergency [about 8:30 p.m. ET Tuesday] and indicated he was disoriented in cloud," said Capt. AlexandreCadieux of the Joint Rescue Co-ordination Centre in Trenton, Ont. "The pilot was concerned that he was disoriented.
"The aircraft control authorities attempted to vector him towards an appropriate landing area. Unfortunately they lost communication with the pilot, which triggered our involvement in the search. We did not regain communication with the aircraft."
That triggered a search involving both a CC-130 Hercules aircraft and CH-146 Griffin helicopter.
The Hercules crew picked up a signal from the plane's emergency locator beacon, but poor weather prevented them from spotting the small plane which had crashed about 20 kilometres south of Whitney, Ont., in a densely forested area of Algonquin Park.
A rescue team was lowered from the Griffin to the crash site where the bodies of two males were found. Police have not released their identities.
The Cessna had left Buttonville Airport northeast of Toronto and was scheduled to travel to Saint-Hubert, Que., on Montreal's South Shore. The flight was then scheduled to return to Buttonville
Ontario Provincial Police have taken over the investigation.
