A gravestone identifying the resting place of seven unknowns from the USS Oklahoma is shown at the National Memorial Cemetery of the Pacific in Honolulu. The Pentagon says it will disinter and try to identify the remains of up to 388 unaccounted for sailors and Marines killed when the ship capsized in the 1941 Japanese bombing of Pearl Harbor.
