 A man walks past a piece of the crashed Malaysia Airlines Flight 17 near the village of Hrabove, eastern Ukraine Monday, July 21, 2014. The plane would seem to have been travelling in the wrong direction for Ukrainian forces to have perceived it as a hostile aircraft coming from Russia, and the rebels don't have an air force. Mr. Churkin said Ukraine would have to answer to international investigators regarding the activities of its air-traffic controllers, why a Ukrainian antiaircraft missile battery in the area of the crash was "hastily removed," and why Ukrainian radar was operating "at an all-time high" on the day of the incident. Finally, Russia categorically denied supplying the rebels with Buk surface-to-air missile systems, or indeed any other weaponry. The SU-25 "fighter jet" Russia claims to have identified close to the airliner is a ground attack aircraft - according to its manufacturer its maximum service height, without weapons, is 7,000m - 3km short of MH17. They claim to have detected a Ukrainian military aircraft within 3-5km of the Malaysian Airliner on Thursday. And if the rebels don't have the Buk missile system, or indeed any other Russian-supplied weaponry - how did they target the dozen Ukrainian military aircraft they have previously boasted of shooting down? Russia denies supporting the insurgency.
– The investigation into what happened to Malaysia Airlines MH17 took big steps forward today, with victims' bodies finally arriving by train in a Ukraine town and Malaysia declaring that the black boxes are in "good condition." But Moscow, in the meantime, sought to cast doubt on the generally accepted theory that pro-Russian separatists were to blame, reports the Wall Street Journal. At an official briefing last night, the defense ministry said that its radar spotted a second aircraft in the vicinity and that it was probably a Ukraine fighter jet, which could have shot down the plane. The air force chief also suggested that a Ukraine missile system could have hit the plane from the ground, and he said satellite imagery suggested that Ukraine had been moving such systems into the area. He offered no proof, but as Katie Stallard at Sky News writes, "Russia doesn't need to prove its case—all it needs is to create one, to insist that there are different versions of events, that there is credible claim and counter-claim." Meanwhile, the refrigerated train carrying passengers arrived in the Ukraine town of Kharkiv, reports the AP. Forensic experts from the Netherlands, which is taking the lead in the investigation, were to prepare the bodies today for transport to Amsterdam, probably tomorrow. Meanwhile, Malaysia's prime minister declared the black boxes to be in "good condition," reports MarketWatch. Malaysia will hold them until they are turned over to international investigators.
