DH125

The de Havilland DH125 is a British twin-engine business jet aircraft that was designed and manufactured by de Havilland Aircraft Company. It was the first jet-powered civil aircraft to be certified by the Civil Aviation Authority (CAA) of the United Kingdom. The DH125 made its first flight in 1964 and entered service in 1965.

The aircraft features a monoplane design with a twin-tailed configuration and a pressurized cabin for high-altitude flight. It has a crew of two and can accommodate up to 12 passengers. The DH125 is powered by two 3,250-pound-force (14 kN)-thrust Bristol Siddeley Viper engines. The aircraft has a cruising speed of 450 mph (720 km/h) and a range of approximately 2,500 miles (4,000 km).

The DH125 initially competed with other business jets such as the Learjet 23, but it struggled to gain market share. Despite its technological advancements, the aircraft's small market size and financial difficulties led to de Havilland's eventual bankruptcy in 1964. However, the DH125 cemented de Havilland's reputation as a leader in British aircraft design and engineering.

The aircraft found use in various roles, including executive transport, medical transport, and overland mapping. A total of 148 DH125s were produced by de Havilland before the company ceased production in 1976. Although several other manufacturers revived production of the type under license, production ceased by the early 1990s.
