The revised design was redesignated the BAC 111 (later known as the One-Eleven), with BAC abandoning the VC11 project to concentrate on the more promising One-Eleven. Market research showed the 59-seat BAC 107 was too small, and the design was reworked in 1961, with passenger capacity growing to 80 seats, and BS75s being discarded in favour of Rolls-Royce Speys. The selected Rolls-Royce Spey low-bypass turbofan Other competing internal projects, such as the Bristol Type 200, were quickly abandoned following absorption of Hunting into BAC. ![]() BAC also continued development of the larger, 140-seat VC-11 development of the Vickers VC10 which it had inherited. The design was reworked into the BAC 107, a 59-seat airliner powered by two 7,000 pounds-force (31 kN) Bristol Siddeley BS75 turbofan engines. The new BAC decided that the Hunting project had merit, but that there would be little market for a 30-seat jet airliner. In 1960 Hunting, under British government pressure, merged with Vickers-Armstrongs, Bristol, and English Electric to form British Aircraft Corporation (BAC). Many other aviation firms also produced designs. Around the same time, Vickers started a similar development of a 140-seat derivative of its VC10 project, the VC11. Hunting Aircraft started design studies on a jet-powered replacement for the successful Vickers Viscount, developing the 30-seat Hunting 107. This led to a variety of designs from the British aerospace industry. In July 1956, British European Airways published a paper calling for a "second generation" jet airliner to operate beside their existing turboprop designs. Several manufacturers raced to release passenger jets, including those aimed at the short-haul market, such as the Sud Aviation Caravelle. In the 1950s, although the pioneering de Havilland Comet had suffered disasters in service, strong passenger demand had been demonstrated for jet propulsion. Noise restrictions accelerated its transition to African carriers in the 1990s, and the last BAC One-Eleven was retired in 2019.ĭevelopment Early development The initial Hunting 107 concept from Hunting Aircraft It was replaced by the newer Airbus A320 and later 737 variants, as well as by the Bombardier CRJ200 regional jet. It also competed with early Boeing 737 variants and was used by several US carriers, as well as multiple British, overseas and European airlines, including Romanian operators. The short haul, narrowbody aircraft was powered by aft-mounted Rolls-Royce Spey low-bypass turbofans, a configuration similar to the earlier Sud Aviation Caravelle and later Douglas DC-9. Total production amounted to 244 until 1982 in the United Kingdom and between 19 in Romania where nine Rombac One-Elevens were licence-built by Romaero. The 119-seat, stretched 500 series was introduced in 1967. The prototype conducted its maiden flight on 20 August 1963, and it was first delivered to its launch customer on 22 January 1965. Originally conceived by Hunting Aircraft as a 30-seat jet, before its merger into BAC in 1960, it was launched as an 80-seat airliner with a British United Airways order on. The BAC One-Eleven (or BAC-111/ BAC 1-11) was an early jet airliner produced by the British Aircraft Corporation (BAC).
