US Coast Guard video of the moment a plane crash-landed in the Hudson River
Divers in New York are searching for both engines of an airliner which crashed in the Hudson River.
They are using sonar to locate the engines which are believed to have detached after the US Airways Airbus A320 hit the water on Thursday.
Officials are also planning to lift the aircraft from the river on Saturday and recover the flight recorders.
New York mayor Michael Bloomberg hailed the pilot, who landed the plane in the Hudson with no loss of life, as a hero.
Mr Bloomberg said he would be giving "incredibly brave" Captain Chesley Sullenberger and his crew the keys to the city.

The mayor also honoured rescuers who pulled all 155 passengers and crew to safety from icy waters.
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.
Focus on 'black boxes'
At a briefing in New York on Friday, National Transportation Safety Board spokeswoman Kitty Higgins said divers and sonar were tracking the course of the plane which plunged in the river just minutes after taking off from LaGuardia airport.

She said rescuers planned to start lifting the plane - which is currently tethered to a pier in Manhattan - on Saturday morning.
A giant crane and a barge have already been brought to pull the stricken airliner.
The plane is still intact, but officials say they will need to ensure it is recovered safely and without causing it to break apart.
The investigation is then expected to focus on recovering the flight recorders to help establish the cause of the crash.
Mr Bloomberg said on Friday that Capt Sullenberger had been "incredibly skilful" but would be unable to speak to the media while investigations were continuing.
