The successful operation of Tu-104 confirmed the practicability of using passenger airplanes with turbojet engines. With this, a new airplane was required for short distance flights, where the comfort of Tu-104 could be combined with the acceptable takeoff and landing characteristics and high economic parameters.
In July of 1958 The Government issued an Order that entrusted Tupolev to develop fast passenger aircraft Tu-124 equipped with two D-20P engines. Besides, the document included provisions on conversing Tu-124 into a transport-ambulance aircraft, and on the possibility to use Tu-124 on unprepared aerodromes.
The factory tests of the first prototype started in March of 1960. In 1961-1962, ten serial airplanes participated in operational tests. Besides the main test program, Tu-124 successfully passed additional tests for takeoff and landing on the unprepared aerodromes.
The first flight of Tu-124 with passengers on board was performed on October 2, 1962 from Moscow to Tallinn. On this date the aircraft started its active work in Aeroflot.
Tu-124 entered the national aircraft industry as the first passenger jet airliner that brought comfort and speed to the regional airlines. In the history of the world’s aircraft industry, Tu-124 is the first Soviet Union passenger airliner equipped with bypass turbojet engines of the Perm Design Bureau.
By the beginning of the 70s, Tu-124 were used at air routes connecting about 50 cities of the USSR. In 1964 the liner entered the international airlines: it flew to Warsaw, Prague, Berlin. Aeroflot was using Tu-124 till the beginning of the 80s when they were finally replaced by Tu-134 powered by the engines also developed by the Perm Design Bureau headed by Pavel Solovyov.
