The captain of a commuter ferry which crashed into a New York City dock has said the vessel suffered a mechanical failure.
He said the ferry would not go into reverse when he tried to dock it. He also told investigators the engines seemed to have failed.
Investigators will determine whether the condition of the ferry backs up the captain's explanation.
More than 70 people were injured when the ferry made a hard landing into the dock on Wednesday.
The NTSB said the crew was also interviewed.
