The crash of flight MH17 on 17 July 2014 was caused by the detonation of a 9N314M-type warhead launched from the eastern part of Ukraine using a Buk missile system. So says the investigation report published by the Dutch Safety Board today. Moreover, it is clear that Ukraine already had sufficient reason to close the airspace over the eastern part of Ukraine as a precaution before 17 July 2014. None of the parties involved recognised the risk posed to overflying civil aircraft by the armed conflict in the eastern part of Ukraine.Below is a video segment from the live presentation.
