The first An-124 military transport aircraft, loaded with disassembled Russian Mikoyan MiG-29 fighter jets, was scheduled to take off from Tretyakovo airport in the Moscow Region, which is operated by Russian Aircraft Corporation MiG, at noon on Monday.
All six fighter jets, which Russia is handing over to Serbia as military-technical assistance, should be delivered by October 6, the source specified.
Since then, the two countries have issued different delivery timeframes, including by this year-end. The source has now told Sputnik that the aircraft are set to be first demonstrated on October 20, during a national military parade, which will mark the anniversary of the liberation of Belgrade in the Second World War.
The assembling of the fighter jets will be done with the assistance of Russian experts.
Russian Defense Minister Sergei Shoigu has been invited to the parade. Russian aerobatic performance group Strizhi, the Swifts, may also take part in the celebrations.
