Shanghai Daily News story with some preliminary details.
Rescuers are searching for two missing people following a helicopter crash in eastern China's Shanghai Port early Thursday.
A MD922 helicopter carrying two Chinese and two foreigners crashed into the mouth of the Yangtze River on Thursday morning after colliding with a Singaporean cargo ship, killing one of those aboard.
The captain of the helicopter, a Canadian, has been rescued, while the other two are still missing.
The East China Sea Rescue Bureau sent two rescue salvaging ships. Despite strong wind and tides, they continued expanding searching scope. By Thursday evening, part of the wreck had been salvaged, but the black box had not yet been found.
The helicopter was being used by the pilot station of the port. It collided with the ship at around 11 a.m. while transporting the ship's pilot. Officials of the Shanghai Municipal Government rushed to the port to handle the affair.
The cause of the accident is still under investigation.
