In this Dec. 7, 1941 file photo provided by the U.S. Navy, a Navy launch pulls up to the blazing USS West Virginia to rescue a sailor during the attack on Pearl Harbor. An excavation crew recently made a startling discovery at the bottom of Pearl Harbor when it unearthed a skull that archeologists suspect is from a Japanese pilot who died in the historic attack. Archaeologist Jeff Fong of the Naval Facilities Engineering Command Pacific described the discovery to The Associated Press and the efforts under way to identify the skull. He said the early analysis has made him "75 percent sure" that the skull belongs to a Japanese pilot. (AP Photo/U.S. Navy, file)
