High Quality Content by WIKIPEDIA articles! The Tupolev Tu-104 (NATO reporting name: Camel) was a twin-engined medium-range turbojet-powered Soviet airliner and the world`s first successful jet airliner. Although it was the fourth jet airliner to fly (following, in order, the British de Havilland Comet, Canadian Avro Canada C102 Jetliner, and French Sud Caravelle), the Tu-104 was the second to enter regular service (with Aeroflot) and the first to provide a sustained and successful service (the Comet had been withdrawn following a series of crashes due to structural failure). The Tu-104 was the sole jetliner operating in the world between 1956 and 1958.
