Antarctic exploration helicopter rescued from sea off Shanghai

Rescuers have managed to recover the wreckage of a helicopter that crashed in the East China Sea off Shanghai. The copter had served China's Antarctic exploration ship, Xuelong (雪龙）, and was carrying four men when it crashed near the Yangtze River on Sunday mid-morning. Three men were rescued and rushed to the hospital. One of the men is in serious condition, but the other two are stable. The search for the fourth man - a mechanic - is still ongoing. While the exact cause of the crash has yet to be determined, authorities say thick fog was probably the culprit. Source: Xinhua
