The search for the missing Malaysia Airlines jet entered a new stage Friday when navy ships deployed stingray-shaped sound locators in a remote stretch of the Indian Ocean, in an increasingly urgent hunt for the plane's data recorders before their beacons fall silent.
Officials leading the multinational search for Flight 370 said there was no specific information that led to the underwater devices being used for the first time, but that they were brought into the effort because there was nothing to lose.
An arduous weeks-long hunt has not turned up a single piece of wreckage that could have led the searchers to the plane and eventually to its black boxes, which contain key information about the flight. The current underwater search could be completed within a week, Australian search officials said on Saturday. (AP)
