The reconstruction of the wreckage of Malaysia Airlines flight MH17 tells its own vivid story of the impact of the missile that destroyed the aircraft last July, killing all 298 people on board.

The crumpled wreckage, stretching from the nose to the business class cabin, clearly showed the puncture holes where shrapnel from a Buk warhead penetrated the cockpit, killing its three occupants instantly.

The reconstruction was the most intricate part of one of the most complex air crash investigations in history, involving the recovery of thousands of fragments of wreckage from across 50 square kilometers of a war zone in eastern Ukraine.
