New information emerged in the investigation into the disappearance of Malaysia Airlines Flight 370. The effort got a vote of confidence that it is headed in the right direction.
“We have very much narrowed down the search area, and we are very confident that the signals that we are detecting are from the black box on MH370,” Australian Prime Minister Tony Abbott told reporters during an official visit to China.
Black boxes are the plane’s flight data recorder and the cockpit voice recorder.
Locator beacons attached to them are designed to emit high-pitched signals, or pings.
Over the past week, four such pings have been detected by a ping locator towed by the Australian vessel Ocean Shield.
