The U.S. Navy has ended a three-day search for a sailor who is believed to have gone overboard during operations aboard the USS Stethem in the South China Sea. A statement on Friday, Aug. 4, 2017, said that U.S., Japanese and Chinese navy vessels and aircraft spent 79 hours combing roughly 10,000 square miles (25,900 square kilometers) of the South China Sea west of the Philippines, demonstrating what it called “the common bond shared by all mariners to render assistance at sea.” (AP Photo/Paul Traynor, File)
