The Cessna 500 Citation 1 is a pressurized, entry-level business jet that made its first flight in September of 1969 and was FAA certified in 1971. Equipped with turbofan engines (rather than turbojet) and straight wings (rather than swept), the aircraft would be suitable for operations from shorter airfields in order to compete in the light-to-medium twin turboprop market. This made the Model 500 much slower than the competing Lear 25 and earned it nick-names such as “Slowtation” and “Nearjet”.
