In late 1958, Boeing announced a design study for a twin engined feeder airliner to complete the family of Boeing passenger jets. In February 1965, the first order was placed and the project went ahead. The 737 has since become the best selling commercial aircraft in aviation history with 8,000 being built as of April 16, 2014.
