The Russian company that manufactures the Buk ground-to-air missile system plans to issue a report on the July 2014 downing of a Malaysian Airlines passenger jet over eastern Ukraine on October 13, the same day the Dutch Safety Board plans to issue the results of its investigation into the incident.
Almaz-Antei said in a press release on October 8 that it had carried out the detonation of a Buk missile under a decommissioned Boeing passenger jet in a "life-scale, real-time" experiment as part of its investigation into the disaster.
The company said that preliminary results from the experiment support the conclusions that the firm presented in June -- namely, that the plane was shot down by a Buk missile fired from territory controlled by the Ukrainian military.
The Dutch Safety Board plans to issue its report on October 13 as well.
In July, a preliminary report on the investigation's findings was released, saying flight MH17 was brought down by a Buk missile launched from an area held by Russia-backed separatists.
Russia has denied providing Buk missiles to the separatists in eastern Ukraine.
MH17 was shot down over Ukraine's Donetsk Oblast on July 17, 2014, killing all 298 people on board.
