Crashed AirAsia's tail hoisted from sea in search for boxes

Investigators searching for the crashed AirAsia plane?s black boxes lifted the tail portion of the jet out of the Java Sea on Jan. 10, two weeks after it went down, killing all 162 people on board.
                   
It was not immediately clear whether the cockpit voice and flight data recorders were still inside the tail or had detached when the Airbus A320 plummeted into the sea Dec. 28. Their recovery is essential to finding out why it crashed.

Intermittent underwater ping-like sounds were picked up Jan. 9 about a kilometer (half a mile) from where the tail was located, but it was unclear whether they were coming from the recorders. It was possible the signals were coming from another source.
                   
No metal was detected at the ping location, and Nurcahyo Utomo, a National Commission for Transportation Safety investigator, said the sounds could not be confirmed.
                   
The discovery of the tail on the ocean floor earlier in the week was a major breakthrough in the slow-moving search that has been hampered by seasonal rains, choppy seas and blinding silt from river runoff. Officials were hopeful the black boxes from Flight 8501 were still inside the tail.
                   
The last contact the pilots had with air traffic control, about halfway into their two-hour journey from Surabaya, Indonesia, to Singapore, indicated they were entering stormy weather. They asked to climb from 32,000 feet (9,753 meters) to 38,000 feet (11,582 meters) to avoid threatening clouds, but were...
