Development
The Cessna 620 was conceived as an executive transport with design goals that included all-weather capabilities, a pressurized and air-conditioned cabin, a multi-engine layout for safety, a reasonable price and 8 to 10 seats. The project commenced in September 1953, with first flight of the prototype,
registered N620E (construction number 620) on 11 August 1956, the test pilots reporting that the aircraft had met its goals.
