If the massive undersea search for Malaysia Airlines Flight 370 turns up nothing by the end of May, the three countries leading the effort will return to the drawing board, Malaysia's transport minister said Saturday.
Liow Tiong Lai told a select group of foreign reporters on the eve of the anniversary of the plane's disappearance during a flight from Kuala Lumpur to Beijing that he remains cautiously optimistic that the Boeing 777 should be in the area of the southern Indian Ocean where the search has been ongoing.
