(NEW YORK) -- A woman visiting New York to celebrate her 40th birthday died trapped in the back seat of the helicopter that spun out of control and plunged into New York City's East River on Tuesday.
The passengers were four members of a British family on holiday to celebrate Sonia Marra Nicholson's birthday.
The other three passengers were Nicholson's partner Helen Tamaski, her mother Harriet Nicholson and her stepfather Paul Nicholson, officials said.
Tamaski is in critical condition at Bellevue hospital. Harriet Nicholson is also at Bellevue and in stable condition. Paul Nicholson, 72, is in stable condition at New York University Hospital.
Paul and Harriet Nicholson are British citizens who live in Portugal and Sonia Marra Nicholson and Helen Tamaski were living in Australia.
Three family members and the chopper pilot were almost immediately pulled ashore Tuesday afternoon while divers searched frantically for the final passenger. Rescue personnel immediately began performing heart compressions on one of the individuals initially pulled from the water and who appeared to be unconscious.
Sonia Marra Nicholson was recovered more than two hours after the crash at 5 p.m. and pronounced dead.
"I just hope it is the only fatality and our prayers are with those in the hospital," New York's Mayor Michael Bloomberg said.
The Bell 206 helicopter took off from a heliport at 34th Street. Joy Garnett told ABC News's New York affiliate WABC-TV that she saw the chopper lift off and almost immediately begin to spin around several times and then plunge into the river.
"He took off and spun," one official said. The pilot tried to turn it around and land, but he missed by 40 feet, officials said. The chopper landed in 50 feet of water and sank within minutes.
