What type of plane was it?
The crashed plane was a Boeing 777-200ER, the same model as that of Malaysia Airlines flight MH370, which disappeared while travelling from Kuala Lumpur to Beijing in March.
Aircraft: Boeing 777-200ER
Left Amsterdam: 10:15 GMT
Lost contact: 14:15 GMT at 10,000m (33,000ft)
According to Malaysia Airlines, the plane departed Amsterdam's Schiphol Airport at 10:15 GMT (12:15 local time) on 17 July and was due to arrive at Kuala Lumpur International Airport at 22:10 GMT (06:10 local time).
The airline lost contact four hours later at 14:15 GMT - 50km from the Russia-Ukraine border.
Though Ukrainian military aircraft have been shot down over eastern Ukraine by rebels, and the area has been the scene of fierce fighting, the route taken by the Malaysian jet appears to have been subject to no flight restrictions, the International Air Transport Association, an industry group, said. Eurocontrol, a European air safety organization, said the plane apparently was flying at approximately 10,000 meters, which was authorized, although Ukrainian authorities had closed the airspace at lower altitudes.
What caused the crash?
Ukrainian government adviser Anton Herashchenko alleges that the plane was hit by a missile fired by a Buk launcher - a Russian-made, medium-range surface-to-air missile system.
Ukrainian authorities later release a recording they say is a conversation between pro-Russian militants admitting to shooting down the plane.
The US has said the plane was brought down by a missile, but it is unclear who fired it.
Separatist leader Alexander Borodai accused the Ukrainian government of downing the airliner itself.
"Apparently, it's a passenger airliner indeed, truly shot down by the Ukrainian air force," he told Russia's state-run Rossiya 24 TV broadcaster.
Both the Ukrainian government and pro-Russian rebels who have been fighting in the region have denied shooting it down.Buk surface-to-air missile system
