The Tupolev Tu-104 (NATO reporting name: Camel) was a twin-engined medium-range turbojet-powered Soviet airliner. After the British de Havilland Comet and Canadian Avro Jetliner, the Tu-104 was the third jet airliner to fly and the second to enter regular service. Known in the west by its NATO moniker, its arrival in London during a 1956 state visit shocked Western observers.

[edit] Development

At the beginning of the 1950s, the Soviet Union's Aeroflot airline desperately needed a modern airliner with better capacity and performance than any Soviet plane then in operation. The design request was filled by the Tupolev OKB, which based their new airliner on its Tu-16 'Badger' strategic bomber. The wings, engines, and tail surfaces of the Tu-16 were retained in the airliner, but the new design adopted a wider, pressurised fuselage to accommodate 50 passengers. The first flight of first serial Tu-104 was on November 6, 1955 on Kharkiv plant in Ukraine.

By the time production ceased in 1960, about 200 had been built. Aeroflot did not retire the Tu-104 from civil service until 1981. CSA Czechoslovak Airlines, the Czechoslovak national airline, bought a small number of Tu-104As configured for 81 passengers.

Following its removal from civil service, several disbanded aircraft were transferred to the Soviet military, which used them as staff transports and to train cosmonauts in zero gravity.
