Footage has emerged of a helicopter crashing into water in Hawaii.
The aircraft, had five people on board, when it came down near Pearl Harbor.
A 16-year-old boy is in a critical condition, following the crash.
Information was not available about two others on board, including the pilot.
In the footage, a man on the shore was heard to say “Oh, c***” as the helicopter smashed into the water.
Members of the public were reported to have jumped in to pull the victims to safety.
US Navy spokeswoman Agnes Tauyan said the private helicopter went down near the Arizona Memorial visitor centre and then sank.
Shawn Winrich uploaded the video to YouTube.
He said: “My prayers best regards and wishes go to the families involved. 4 adults were known to survive, the minor is unknown at this time. I just verified the tail numbers from my pics. I was on that exact helicopter 2 weeks ago with Genesis helicopters. It was a wonderful flight when we got to it. We were delayed taking off and had to sit on the taxiway hovering, waiting for the airways to clear for the plane that crash landed on the waterway due to engine and landing gear failure. Our flight was delayed approximately 30-45min. Until FAA opened up the airway.”
