Investigators now look closer to solving the riddle of where missing Malaysian Airlines flight MH370 met its end. But they still have little idea why, so the search for the wreckage, and the all-important black box data recorder, goes on.
So far, cost seems to have been no object. When Hishammuddin Hussein was asked recently how much money was being spent on the search, the Malaysian defence minister stressed it had not been an issue in discussions with other countries.
"Nobody, not the Malaysian government, none of our partners, have talked about dollars and cents," he said on Saturday. "It's all about trying to find the aircraft. It did not even cross our minds."
But the longer the search continues, the more countries may have to consider their commitment to what could be a long haul – it took two years to find the black box in the case of Air France flight 447, which crashed into the Atlantic in 2009.
