No Clarity on Cause One Year After MH17 Ukraine Crash

A year since a Malaysia Airlines Boeing 777 was blown out of the sky over war-ravaged eastern Ukraine — killing 298 people — there has been little official word of progress in determining what brought down Flight MH17. One of the probes under way reportedly points toward a ground-to-air missile fired from a village held by Russia-backed separatist rebels, but the report isn't to be public for months. Another investigation trudges forward with painful slowness, and contradictory theories emerge from Moscow. Most evidence points to the plane, which departed from Amsterdam en route to Kuala Lumpur, Malaysia, being taken down by a missile over an area controlled by pro-Russia rebels. But whether the missile was fired from a warplane or from the ground remains unclear, as is the question of who launched it.
