Live: 2 ships start black box hunt for MH370 jet

Crews searching for the missing Malaysia Airlines jet launched a targeted underwater hunt on Friday for the plane’s black boxes along a stretch of remote ocean, with just days left before the devices’ batteries are expected to run out. The Australian navy ship Ocean Shield, which is dragging a towed pinger locator from the US Navy, and the British navy’s HMS Echo, which has underwater search gear on board, will converge along a 240-kilometer (150-mile) track in a desolate patch of the southern Indian Ocean, said Angus Houston, the head of a joint agency coordinating the search.
