The Bristol Type 200 was a proposal for a short-range aircraft by the Bristol Aeroplane Company in 1956. Although it was designed in response to a specification issued by British European Airways (BEA), the Type 200 was larger than the airline's requirements and was closer to the Boeing 727 in size and range. The project was cancelled when BEA selected the Hawker Siddeley Trident instead. The Trident went on to have a production run of 117, while the 727 had a production run of over 1800. Along with the Vickers V-1000, it is seen by some as one of the great "what ifs" of British aviation, although it never got beyond the drawing board. 〔As a Bristol employee at the time〕 ==Development== In 1955 BEA issued a specification for an aircraft to replace its Vickers Viscount and Vickers Vanguard turboprop airliners. The airline's requirements were for an aeroplane that could carry a payload of 100 passengers over a range of .〔 Along with the Bristol Aeroplane Company, de Havilland, Avro and Vickers proposed designs based around BEA's specification. but the B200 was the only Trijet proposal and it won the competition. De Havilland, however, were in trouble after the Comet disaster but Bristols had a full workload. The British Government asked Bristols to share the B200 work with DH and, in return, were promised the Government's support on their Type 188 Mach 2 fighter project. The two companies worked together unhappily for about 6 months and it was obvious that they were not compatible. The Government then required DH to form another company large enough to continue the development without Bristols involvement. Accordingly "Airco" was formed by DH. A number of European and American Airlines became interested in the aircraft and Boeing were aware of this. BEA then decided that afterall the B200 design was over-large for its needs and requested that the aircraft be scaled down and this smaller version became known as the Trident. Boeings saw this scaling-down as a mistake and took the initiative of developing the Boeing 727 as almost a B200 replica. History recalls that BEA and DH subsequently realised that the scaling down had been a costly mistake and DH hurriedly set about a "scaling up" exercise to form Tridents 2 and 3 derivatives. But the market had by then been lost to DH and captured by Boeing with large sales for its 727. The design of the Type 200 was in fact marginally larger than the specifications that were issued by BEA. This reflected the opinion of Archibald Russell (Chief Designer at Bristol) and his team, who believed that a larger aircraft had better potential in the international market.〔 The Type 200 was close to the Boeing 727 in size and range. The project attracted interest from various European and American airlines, including Pan Am, who invited senior members of the design team to a meeting in the US. Under pressure from the British government to merge with other aerospace companies, Bristol collaborated with Hawker Siddeley on the Type 200, but ultimately in 1958 BEA selected the Trident and the Type 200 was cancelled.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Bristol Type 200」の詳細全文を読む スポンサード リンク
