This is the second fatal accident of Ukrainian Air Force Su-27 aircraft this year. In October, a Ukrainian Su-27UB two-seater fighter plane crashed during a clear sky-2018 exercise in Ukraine, killing an American pilot and a Ukrainian pilot.
After the crisis in the Kachi Strait, the domestic situation in Ukraine was turbulent, which made the Ukrainian Air Force increase its frequency of operation.
