Group marks death of Pearl Harbor attack architect

A group from the U.S. and Japan is trekking to a remote Pacific island jungle to document what is considered one of the most important wreck sites of World War II: where American fighters shot down a Japanese bomber carrying the mastermind of the Pearl Harbor attack. Three members of a New York WWII research organization and a Japanese aviation expert plan to visit the crash site on Bougainville, part of Papua New Guinea, on Wednesday, the 75th anniversary of Admiral Isoroku Yamamoto's death.
