The De Havilland Canada DHC-6 Twin Otter is a versatile, twin-engine turboprop aircraft renowned for its exceptional short takeoff and landing (STOL) capabilities. First flown in 1965, it was designed to operate from unprepared airstrips, gravel bars, water, snow, and ice, making it invaluable in remote and challenging environments. Originally produced by De Havilland Canada, the type went through several ownership changes before production rights passed to Viking Air of Canada, which relaunched manufacturing as the Series 400 in 2010. The aircraft has been operated in configurations ranging from passenger transport and cargo to medevac, parachute dropping, and scientific research. With over 900 aircraft produced across multiple series, the Twin Otter remains in widespread service globally, particularly with regional and commuter operators in Africa, the Pacific, Southeast Asia, and polar regions. Its reliability, versatility, and ability to use floats or skis have made it one of the most enduring utility aircraft ever built.
