If the Malaysia Airlines plane still isn't found, the search for MH370 will end this summer.
The search of a 46,000-square mile area of the southern Indian Ocean will most likely end in July, according to Australian Transport Safety Bureau Chief Commissioner Martin Dolan.
Speaking to NBC News, "If we don't find the aircraft within the priority search site … that's the point at which the search will stop," Dolan said.
Dolan said that Malaysia, China and Australia involved in the search and they don't have the appetite to widen the search area, having already spent almost $100 million mapping and scanning the ocean floor.
But new discoveries of possible wreckage — one last week in Mozambique and another reported Sunday on Reunion Island — had raised optimism that they are looking in the right place, Dolan added.
