Crew members ride a fast response craft from the Australian Defence Vessel Ocean Shield as they continue to search for debris in the southern Indian Ocean for the missing Malaysian Airlines flight MH370 in this picture released by the Australian Defence Force April 8, 2014. A robotic search vehicle is likely to be sent deep into the Indian Ocean on Tuesday to look for wreckage of a missing Malaysian jetliner on the sea floor, as officials say the chance of finding anything on the surface has dwindled. Angus Houston, head of the Australian agency coordinating the search for Malaysia Airlines Flight MH370, said the month-long hunt was at a critical stage given the black box recorder batteries were dying - or had died.
