The British Aerospace 125 is a twinjet mid-size business jet. Originally developed by de Havilland and initially designated as the DH.125 Jet Dragon, it entered production as the Hawker Siddeley HS.125, which was the designation used until 1977. Later on, more recent variants of the type were marketed as the Hawker 800. More than 60% of the total sales of the aircraft were to North American customers. It was also used by the Royal Air Force as a navigation trainer, as the Hawker Siddeley Dominie T1, and was operated by the United States Air Force as a calibration aircraft, under the designation C-29

Design

The BAe 125 is a low-winged monoplane, powered by two engines mounted on the rear fuselage. It features a slightly swept wing, which is based on the larger de Havilland Comet wing planform, and uses large slotted flaps and airbrakes for operating from small airfields; the aircraft can be flown from hardened grass airstrips. The aircraft has a cylindrical fuselage with a one-piece wing mounted on the underside of the fuselage; most of the manufacturing and assembly work on the wing and fuselage is able to be done with them as separate items with the two being joined late in the production process. The wing has integral fuel tanks which contain most of the fuel.

In 2013, the FAA modified its rules to prohibit the operation of jets weighing 75,000 pounds (34,000 kg) or less that are not stage 3 noise compliant, specifically mentioning the 125 series of aircraft. This required any aircraft of the type either to have compliant engines installed, or to be fitted with a hush kit, to fly over most of the United States after 31 December 2015

The aircraft went through many designation changes during its service life. Hawker Siddeley had bought de Havilland the year before the project had started, but the legacy brand and "DH" designation.
