(Reuters) - Rescue teams searched for a downed Army Black Hawk helicopter with five crew members aboard that was last reported off the west coast of Hawaii, the U.S. Coast Guard said on Wednesday.

Coast Guard Hercules and Army Black Hawk aircrews spotted debris near Kaena Point, Oahu at 11:28 p.m. local time after staff at Wheeler Army Airfield said they had lost contact with one of their UH-60 Black Hawk aircrews, the Coast Guard said.

Rescue crews searched for five missing people who were training between Kaena Point and Dillingham Airfield, also on Oahu, when communications were lost.
