Underwater devices look for Army helicopter crew off Hawaii

HONOLULU — The Navy is using remotely operated underwater vehicles and sonar to help in the search for a missing Army helicopter and its five-member crew off Hawaii.

The search began late Tuesday when an Army Black Hawk helicopter with five soldiers on board went missing in waters off Oahu during nighttime training.

No one has been found, but search and rescue teams have recovered a helmet and a piece of what appeared to be fuselage.

A response team led by the U.S. Coast Guard expanded its search area Thursday to 50 miles off Kaena Point on Oahu's north shore.

The two Black Hawk UH-60 crews were training between Kaena Point and Dillingham Airfield when communications were lost with one of the aircraft.
