The Russian concern ‘Almaz-Antey’, which produces the ‘Buk’ anti-aircraft missile systems, claimed that a missile was fired at MH17 from the village of Zaroshchenskoye. However, this version was convincingly refuted by the Russian media, in particular ‘Novaya Gazeta’ newspaper: as it turned out, at the time of the tragedy, the village of Zaroshchenskoye was under full control of the pro-Kremlin militants. The newspaper's conclusions were also confirmed by the Joint Investigation Team www.om.nl/onderwerpen/mh17-crash/@96068/jit-flight-mh17-shot/, . According to it, the Malaysian Boeing was shot down from the area of the village of Pervomaiskoye (Donetsk region), which is located 50 km from Zaroshchenskoye.
Recently, investigators of the independent group ‘Bellingcat’ and ‘The Insider’ site have identified, to a high degree of certainty, a key figure sought by the Joint Investigation Team (JIT), the Dutch-led criminal investigation into the downing of Malaysian Airlines Flight 17 (MH17): Russian colonel-general Nikolai Tkachev, who now occupies the position of chief inspector of the Central Military District of Russia. www.bellingcat.com/news/uk-and-europe/2017/12/08/russian-colonel-general-delfin/,
As for the second explanation given for the crash, that the plane crashed for "technical reasons" it is clearly not true which shows the recurring attempts to use disinformation purely to confuse regarding the situation.
