The de Havilland Canada Dash 7 (DHC-7) is a renowned four-engine turboprop airliner celebrated for its exceptional Short Take-Off and Landing (STOL) capabilities, allowing it to operate from rough, short runways, making it ideal for remote areas like the Canadian wilderness or Antarctic bases. Key features include its high-mounted wing, large propellers for quiet operation, and a rugged design, with variants seating around 50 passengers. Though it had limited commercial success, it remains valued for its reliability in demanding environments, with operators like the British Antarctic Survey and Air Tindi still flying them.
