The Hawker 1000 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. Later on, more recent variants of the type were marketed as the Hawker 800.
Various interiors were offered, with a high degree of passenger comfort. In an executive configuration, the flight deck is separated from the main passenger cabin; the single entrance of the aircraft, located directly behind the cockpit and forward of the passenger cabin, forms a vestibule area in which luggage can be stored and meals prepared during flight.
An unobstructed cabin floor with 1.75 m of headroom and a 0.91 m wide cabin door also allowed the loading of bulky equipment. The rear of the fuselage has a large equipment bay and, on some aircraft, one or two additional fuel tanks for extended operations.
