A Boeing 737 cargo plane has crashed into the water off the coast of Hawaii after reportedly experiencing engine trouble.
There were two pilots on board and both have been rescued, according to the Federal Aviation Authority (FAA).
One is critically injured in intensive care.
The other pilot was being taken back to shore by a Coast guard rescue boat, ABC reported.
An FAA investigation into the crash will be launched.
Flight tracking website Flightradar24 tweeted the plane was a 737-200 cargo aeroplane operated for the carrier Transair since 2014.
It was built in 1975 and first delivered to Pacific Western Airlines.
Transair Flight 810 left Honolulu bound for Kahului at 01:33 local time (11:33 GMT), Flightradar 24 said, but turned back quickly afterwards and crashed into the water after just minutes in the air.
The Transair website reported it has been in business since 1982 and is one of Hawaii’s biggest air cargo operators.
It has a fleet of five Boeing 737s.
This aircraft is not the same as a Boeing 737 Max which was temporarily grounded by authorities after two fatal passenger airline crashes in 2018 and 2019 respectively.
The 737 Max was cleared to fly again by US regulators in 2020.
