The Antonov An-70 (Ukrainian: Антонов Ан-70) is a four-engine medium-range transport aircraft, and the first aircraft to take flight powered only by propfan engines. It was developed in the late 1980s by the Antonov Design Bureau to replace the obsolete An-12 military transport aircraft.
The aircraft was disassembled on site and relocated to the local "Polyot" aircraft repair factory in Omsk and restored to flying condition. [2] The damaged airframe required months of repair and as of 2012 is the only AN-70 in existence, still performing important flight testing.
