RCMP and local authorities in Birch Hills County in northern Alberta are investigating the New Year’s Day crash of a Robinson R44 helicopter that killed all four people onboard. Details are scant but the aircraft reportedly went down in a farmer’s field near the town of Spirit River, about 485 km. north of Edmonton. The ELT on the helicopter triggered in the crash and the RCMP would have been notified by the Joint Rescue Coordination Centre to investigate the source of the signal.
