The plane's crew and rescue teams averted a tragedy, the mayor said
New York's mayor has hailed the pilot of a plane which crashed in the Hudson River with no loss of life as a hero.
Michael Bloomberg said he would be giving "incredibly brave" Captain Chesley Sullenberger and his crew the keys to the city.
Mr Bloomberg also honoured rescuers who pulled all 155 passengers and crew from the US Airways Airbus A320 to safety.
Investigators are now searching for the jet's two engines that have detached and are believed to be in the river.
At a news conference in New York, National Transportation Safety Board spokeswoman Kitty Higgins said the agency's crews were using sonar equipment to search for the engines.
Ms Higgins said that rescuers planned to lift the plane from the river on Saturday.
The investigation is then expected to focus on recovering the flight recorders from Flight 1549 and interviewing the crew about what happened after it took off from New York's LaGuardia airport en route to Charlotte, North Carolina on Thursday afternoon.
Capt Sullenberger said earlier that the crash was caused by birds flying into the engines. Investigators say they plan to interview him on Saturday.
One person suffered two broken legs in the crash and paramedics treated 78 patients, most for minor injuries.
At a news conference in New York, Mr Bloomberg said Capt Sullenberger had been "incredibly skilful" but would be unable to speak to the media while investigations were continuing.

Mr Bloomberg said the writer Ernest Hemingway defined heroism as "grace under pressure".
"I think it's fair to say that Captain Sullenberger displayed that yesterday. His brave actions have inspired millions of people in this city and millions more around the world," he said.
Mr Bloomberg praised the plane's crew
The mayor also presented awards to other uniformed and civilian personnel involved in the rescue.
He said the city's "finest and bravest" workers had made "split-second decisions that resulted in a dramatic rescue".
"Because of their efforts and the calm, steady leadership shown by the plane's pilot and crew, miraculously all 155 people on that plane made it to safety," he said.
The White House said President George W Bush had telephoned Capt Sullenberger to thank him for his actions.
Mr Bush praised the former fighter pilot for his "amazing skills in bringing his plane down safely, for his bravery, and for his heroic efforts to ensure the safety of his passengers and the people in the area," said spokeswoman Dana Perino.
