The U.S. Coast Guard said Thursday it was now searching up to 50 miles (80 kilometers) off Hawaii for five soldiers missing after their Black Hawk helicopter crashed during nighttime training.
Swift and dynamic currents prompted the rapid expansion. About 24 hours earlier, the search was focused on waters about 5 miles (8 kilometers) off shore.
"This is normal and we have the assets, and the resources to plan for it," Lt. Scott Carr, a spokesman for the Coast Guard in Hawaii, said as rescuers prepared for a third night of searching.
