"The design of the aircraft began in 1963, on the personal initiative of Ilyushin. The small liner was required to intervene 24 passengers and to transport them up to 1000 kilometres, with a minimum length of a concrete runway of only 400 meters. The cruising speed of the passenger aircraft was to be at 700 km level.
Such characteristics, in particular the very short running length, would have made the Il-70 "king" of airlines a small length. The same-124 and an-24 took twice the distance to takeoff. Well, flying data, coupled with a high level of comfort, did not leave any chance for the closest competitors of the Ilyushin Miracle to be in the Soviet Union or the West. It was for this reason that the liner initially received "green light" for further design from the USSR civilian Air fleet. However, during the final review of the project, the development of the Ilyushin-70 was abandoned.
The military played a role in this, which, of course, considered the liner for its own use, and which considered it unnecessary to launch in serial production, on an equal footing with an-24 and Tu-124, one more aircraft. Another reason for the rejection of the Ilyushin-70 was that the civil-fleet leadership itself, initially rather which development of Ilyushin, eventually opted for another project of Project aircraft, Yakovlev Yak-40, which eventually became the legend of Soviet aviation. And a unique IL-70, "Il'jushino miracle," of further Soviet development, for those reasons it was left only on paper."
