A warship with an aircraft black box detector was set to depart Australia on Sunday to join the search for the missing Malaysian jetliner, a day after ships plucked objects from the Indian Ocean to determine whether they were related to the missing plane. None were confirmed to be from the plane, leaving searchers with no sign of the jet more than three weeks after it disappeared. The search continued on Sunday with 10 aircraft and eight ships tasked to scour the Indian Ocean, after early sightings in the new search zone drew a blank.
