British Aerospace 125

The British Aerospace 125 is a twinjet mid-size business jet, originally developed by de Havilland as the DH.125 Jet Dragon and put into production as the Hawker Siddeley HS.125, the designation used until Hawker Siddeley was merged into British Aerospace in 1977. In 1961 de Havilland began work on a small business jet to replace its piston-engined Dove, with design goals of a range of at least 1,000 miles and an engineering philosophy that favoured reliability and conventionality. The first of two prototypes flew on 13 August 1962. Later variants were marketed as the Hawker 800 and Hawker 1000, and more than 60 percent of total sales went to North American customers. The Royal Air Force used it as the Hawker Siddeley Dominie navigation trainer, retired in 2011, and the United States Air Force operated it as the C-29 calibration aircraft.
