Helicopter, Plane Crash Over Hudson River, Killing 9 (VIDEO)
UPDATE: Fox news talks with three eyewitness and shows the first images of the crash.
NEW YORK -- A small plane collided with a sightseeing helicopter carrying Italian tourists over the Hudson River on Saturday, scattering debris in the water and forcing people on the New Jersey waterfront to scamper for cover. Authorities believe all nine people aboard the two aircraft were killed.
Another helicopter pilot on the ground at the heliport for Liberty Tours, which operated the doomed sightseeing craft, saw the plane approaching the helicopter and tried to radio an alert to the pilots, police Commissioner Raymond Kelly said. The warning wasn't heard or didn't happen in time.
The collision, which Mayor Michael Bloomberg said was "not survivable," happened just after noon and was seen by thousands of people enjoying a crystal-clear summer day from the New York and New Jersey sides of the river.
"First I saw a piece of something flying through the air. Then I saw the helicopter going down into the water," said Kelly Owen, a Florida tourist at a Manhattan park. "I thought it was my imagination."
The two aircraft went down just south of the stretch of river where a US Airways jet landed safely seven months ago. But this time, there was no miracle.
"This is not going to have a happy ending," Bloomberg said. Hours after the collision, he said he thought it fair to say "this has changed from a rescue to a recovery mission."
The National Transportation Safety Board was investigating the cause of the collision.
Two bodies were recovered in the water, one floating free and one in the wreckage, and other bodies were spotted in the debris in the river, the mayor said. The crash victims included five Italian tourists and a pilot on the helicopter and the three people on the plane, including a child, Bloomberg said.
Witnesses described seeing a low-flying plane smashing into the helicopter, and then wreckage scattering. One of the plane's wings was severed by the impact.
Buzz Nahas was walking along the Hoboken, N.J., waterfront when he heard the impact, then looked up to see the plane without one of its wings "fluttering" into the water.
"There was a loud pop, almost like a car backfire," he said. "The helicopter dropped like a rock."
The plane, headed for Ocean City, N.J., left Teterboro Airport in New Jersey at 11:54 a.m., the Port Authority of New York and New Jersey said in a statement. It had landed at the airport 25 minutes earlier with the pilot aboard to pick up two passengers.
The plane had started its journey in Pennsylvania, an official familiar with the plane's flight path told The Associated Press on condition of anonymity because he wasn't authorized to speak publicly.
The plane, a Piper PA-32, was registered to LCA Partnership in Fort Washington, Pa. The company's officials couldn't immediately be identified. The helicopter was a Eurocopter AS 350 owned by Liberty Tours, a sightseeing and charter company. It was struck by the plane shortly after lifting off from a heliport on Manhattan's West side.
On the Hoboken, N.J., waterfront, people scattered as pieces of debris fell from the sky. A wheel from one of the aircraft lay on Hoboken's Sinatra Drive.
"We saw the helicopter propellers fly all over," Hoboken resident Katie Tanski said.
Afterward, much of the wreckage sank quickly into the river.
The accident happened in a busy general aviation corridor over the river that is often filled with sightseeing craft on nice days.
Pilots have some freedom to pick their own route, as long as they stay under 1,000 feet and don't stray too close to Manhattan's skyscrapers. The skies over the river are often filled with pleasure craft, buzzing by for a view of the Statue of Liberty.
Steve Riethof, a volunteer at the Aviation Hall of Fame in Teterboro, said Saturday that pilots headed for the Jersey Shore from Teterboro generally fly through Manhattan.
Accidents happen every few years. New York Yankees pitcher Cory Lidle and his flight instructor died when their plane hit a skyscraper while flying a popular sightseeing route in 2006.
In January, the river was the scene of a spectacular aircraft landing that resulted in no loss of life after a US Airways flight taking off from LaGuardia Airport, in Queens, slammed into a flock of birds and lost power in both engines. The plane crash-landed in the river, and all 155 people on board were pulled to safety.
The identities of the victims of Saturday's crash were not immediately released. Italian Foreign Ministry spokesman Maurizio Massari confirmed there were Italians aboard the helicopter and said the ministry was working to find out further details through diplomats and authorities in New York.
Paolo Casali, from Rome, was scheduled to take a helicopter tour with Liberty after noon on Saturday, but her 13-year-old son, Lorenzo, was too scared to go.
"I feel very, really lucky," Casali said. "I think God was in our life. Today is the beginning of a new life, to catch every moment, every minute of this life."
A person who answered the phone at a Liberty Tours office said the company would be releasing a statement. The company runs sightseeing excursions around the Statue of Liberty, Ellis Island and Manhattan at costs ranging from $130 to about $1,000.
Two years ago, a Liberty helicopter fell 500 feet from the sky during a sightseeing trip. The pilot was credited with safely landing the chopper in the Hudson and helping evacuate her seven passengers.
In 1997, a rotor on one of its sightseeing helicopters clipped a Manhattan building, forcing an emergency landing. No one was hurt.
