Joint Rescue Coordination Centre Trenton confirmed the military responded when the plane lost contact shortly after taking off near Fort Smith.

The Air Force, Royal Canadian Mounted Police and Canadian Rangers were all involved in the search-and-rescue, said David Lavallee, a public affairs officer with Search and Rescue Region Trenton.
