Rescuers Pull Survivor From Shangai Chopper Crash.

BEIJING: A helicopter carrying four people crashed and sank in the East China Sea near Shanghai on Sunday, state media reported. Three people were rescued.

The helicopter went down near an estuary of the Yangtze River, the official Xinhua News Agency said. It said the three rescued crew members were treated at a hospital.

Three rescue boats from the China Marine Search and Rescue Center were attempting to locate the sunken helicopter and the missing crew member, Xinhua said.

A man who answered the phone at the search and rescue center's office in Beijing confirmed three of the four people on board were rescued. He refused to give his name or provide more details.

The report said the crash occurred one minute after the helicopter took off from a ship docked in Shanghai named Xuelong, or ``Snow Dragon.''

The ship left Shanghai in October with a crew of 140 scientists, technicians and sailors to carry out a 173-day Antarctic expedition trip, Xinhua said.
