MOSCOW. June 3 (Interfax) - Russian investigators view the presence of a Ukrainian Su-25 warplane in the sky over Donbas as the priority theory of the Malaysia Airlines Boeing 777 passenger jet's crash in July 2014, a source familiar with the case documents told Interfax.
"For the time being, the theory based on Ukrainian Air Force serviceman Yevhen Ahapov's testimony remains priority one for the Russian investigation," the source said.
It was reported earlier that Ahapov had testified to Russian investigators as a witness that he had served with the Ukrainian Air Force and was aware that a Ukrainian Air Force Su-25 piloted by Capt. Voloshyn had been scrambled for a combat mission in the afternoon of July 17, 2014.
"The said plane returned to the airfield empty, and Voloshyn explained to his colleagues that 'a plane happened to be in the wrong place at the wrong time'. The witness learned later that a Malaysian civilian aircraft with passengers on board had crashed earlier in the day," the Russian Investigative Committee reported earlier.
