Hoboken (New Jersey, US), Aug. 10 : Divers pulled a helicopter and four more bodies out of the murky Hudson River on Sunday, days after a midair collision between a sightseeing helicopter and a small plane claimed nine lives.

The dead include three fathers and their three teenage sons. The private plane carried a family from Pennsylvania, and the helicopter held five Italian tourists celebrating a couple''s 25th wedding anniversary, news agency reports said.

Searchers fought swift currents, dealt with visibility as low as one foot (30 centimeters), and dodged debris dumped along the river bottom as they brought four more bodies on to boats. One was found in the fuselage of the helicopter, New Jersey State Police Sergeant Stephen Jones said.

Two bodies are still missing.

A U. S. Army Corps of Engineers crane lifted the twisted wreckage of the helicopter from 30 feet (9 meters) of water. Nearby, a sonar scanner found the small plane wreckage.

New York City police said. More plane wreckage was found farther out in the river under about 50 feet (15 meters) of water.

The collision happened in the same stretch of the Hudson where a US Airways jet landed safely seven months ago. It was the worst air disaster in New York City since a commercial jet crash in Queens killed 265 people in November 2001.

The searches went on as a steady stream of tour boats floated down the Hudson. Restrictions put in place after the crash kept sightseeing helicopter tours grounded Sunday.

Investigators from the National Transportation Safety Board were reviewing flight data from the Teterboro Airport, where the plane took off a little before noon on Saturday.

Additionally, investigators were asking witnesses, thousands of whom were out enjoying a beautiful summer day when the aircraft went down, to provide photos and video capturing the crash and its immediate aftermath. (ANI)
