We start this hour with the Dutch report out today on the downing of flight MH17 over Ukraine.It's the result of a 15-month investigation.The report says the flight crew died instantly after an antiaircraft missile exploded just three feet outside their cockpit windows.The rest of the 298 passengers and cabin crew died soon afterwards.The Malaysia Airlines flight originated in Amsterdam, and most of those who died were Dutch.NPR's Eleanor Beardsley begins our coverage from The Hague.The press conference took place in a hangar beside the partially rebuilt Boeing 777.Recovered sections of MH17's shrapnel-pocked skin were put in place on a frame.Dutch Safety Board head Tjibbe Joustra said 15 months of extensive forensic tests and simulations led investigators to a definite conclusion.Flight MH17 crashed because a 9N314M warhead detonated outside the airplane above the left side of the cockpit.This warhead fits the kind of missile that is installed on the BUK service-to-air missile system.Russia took part in the investigation but accused the Dutch of ignoring its input.Moscow accepts that MH17 was brought down by a missile fired from a Russian-built BUK launcher but disagrees with what kind of missile it was and where it was fired from.Today's report also addressed another troubling issue.Why had the plane flown over separatist-held Eastern Ukraine?
