The Tupolev Tu-104 is a retired twinjet, medium-range, narrow-body turbojet-powered Soviet airliner. It was the second to enter regular service, behind the British de Havilland Comet, and was the only jetliner operating in the world from 1956 to 1958, when the British jetliner was grounded due to safety concerns.In 1957, Czechoslovak Airlines – ČSA, became the first airline in the world to fly a route exclusively with jet airliners, using the Tu-104A variant between Prague and Moscow. In civil service, the Tu-104 carried over 90 million passengers with Aeroflot, and a lesser number with ČSA, while it also was operated by the Soviet Air Force. Its successors included the Tu-124, Tu-134, and Tu-154.
