    CS2F Grumman (de Havilland) Tracker

    The Tracker was a twin-engine fixed-wing aircraft acquired by the Royal Canadian Navy (RCN) to be flown off aircraft carriers for antisubmarine warfare (ASW) as a replacement for the Grumman Avenger. Originally developed for the United States Navy (USN), a Canadian version was manufactured under licence by de Havilland Canada as the CS2F. After unification the plane was redesignated as the CP-121; the Trackers became shore-based aircraft after the aircraft carrier HMCS Bonaventure was decommissioned. The Trackers became fully operational in 1959 and were withdrawn from service in 1989.

    De Havilland Canada DHC-2 Beaver

    The de Havilland Canada DHC-2 Beaver, successor to the Noorduyn Norseman, was the all-purpose bush plane of the Canadian North. (See also Bush Flying in Canada.) The Beaver was sturdy, reliable and able to take off and land on short lengths of land, water and snow. It has been called the best bush plane ever built.

The Beaver helped connect communities in remote areas of Canada, in addition to serving across the globe.
