6. Twin Otter

Canada's northwest territories are rich in gold and diamonds, but running a mining operation in extreme Arctic conditions with very few roads can be tremendously challenging. Enter the Twin Otter, the rugged aircraft of choice in remote Canadian communities. Powered by two turboprop engines, the Twin Otter maneuvers like a bird and is capable of landing just about anywhere--on land, sea, and snow. Follow this mighty plane as she handles icy skies and frozen-lake runways on a series of critical missions.
