"The pilots had reported engine trouble and were attempting to return to Honolulu when they were forced to land the aircraft in the water," the Federal Aviation Administration said in a statement to CNN, adding both crew members were rescued. "The FAA and National Transportation Safety Board will investigate."

The aircraft had taken off from Honolulu's Daniel K. Inouye International Airport at 1:33 a.m., according to Flightradar 24, said the CNN report, adding that shortly after hitting the sky, the plane began turning right and then signaled it was diverting to a nearby airport, Kalaeloa Airport.

The pilots reported they were unable to maintain airspeed and altitude as the  one of two engines on the Boeing 737-200 , according to the LiveATC recordings, and that they suspected the second engine would also fail, the CNN report stated.

One of the crew members requested the air traffic controllers to dispatch  the airport fire department as they suspected that the second engine would also stop working.

The plane went down approximately two nautical miles south of Kalaeloa, the report said, citing an official.

One crew member was rescued by the Coast Guard, while the second was rescued by a local fire department, the official informed CNN.
