Shortly after the end of the Second World War, de Havilland Canada decided to orient itself towards civilian operators. Based on feedback from pilots, the company decided that the envisioned aircraft should have excellent STOL performance, all-metal construction, and accommodate many features sought by the operators of bush planes. On 16 August 1947, the maiden flight of the aircraft, which had received the designation "DHC-2 Beaver", took place. In April 1948, the first production aircraft was delivered to the Ontario Department of Lands and Forests. A Royal New Zealand Air Force (RNZAF) Beaver played a supporting role in Sir Edmund Hillary's famous 1958 Commonwealth Trans-Antarctic Expedition to the South Pole.
