(Zhou Hua / Xinhua via AP, Archive) The second “black box” was recovered from the crash of a Boeing 737-800 in eastern China that killed all 132 people on board last week, Chinese state media reported on Sunday. Firefighters involved in the search found the recorder, an orange cylinder, on a mountain slope about 1.5 meters (5 feet) below the ground, state television network CCTV reported. Experts confirmed that it was the second black box. The researchers were looking for the flight data recorder after finding the voice recorder in the cockpit four days ago. The two logs should help researchers determine what caused the plane to fall from 29,000 feet (8,800 meters) and on a wooded hillside in southern China. Flight MU5735 crashed Monday en route from Kunming in southeastern China to Guangzhou, a major city and export hub near Hong Kong. An air traffic controller tried to contact the pilots several times after seeing the plane’s altitude fall sharply but received no response, officials said. CCTV and the official Xinhua news agency reported the discovery of the flight data recorder, citing officials. China Eastern, one of China’s four largest airlines, and its subsidiaries have grounded all 737-800 aircraft, for a total of 223 aircraft. The carrier said grounding was a precautionary measure, not an indication that something was wrong.
