[1] Leased by Ukrainian Cargo Airways, the aircraft was carrying two Sukhoi Su-27UBK fighters (8524 and 8525) for delivery to the Vietnam People's Air Force, with a planned stopover at Vladivostok.

[1] Unable to continue climbing the aircraft descended until it struck houses in Mira Street, 1,600 metres (5,200 ft; 1,700 yd) beyond the runway end, killing all 23 on board and 49 persons on the ground.

However, just three seconds after lift-off from the runway at a height of 5 metres (16 ft), there was a surge in engine number 3 which caused an increase of the angular velocity of the Antonov.

The damage was aggravated by the ignition of tons of aviation fuel leaked during the crash.A special commission was established to investigate the causes of the disaster.

[2] In an interview with the Moskovsky Komsomolets newspaper, the test pilot Alexander Akimenkov said that the accident could have been caused by the call of a passenger with the Chinese radiotelephone, which affected how the electronics work.
