TSUKUBAMIRAI, Ibaraki Pref. -- Wilma Cook remembers how hard her father tried to discover what happened to her brother, 2nd Lt. Eugene Cook, when his B-29 bomber crashed in Japan during an air raid in March 1945.
She was 22 at the time, and the only thing the family knew was that he was "missing in action."
"We figured that the plane crashed because it never returned from the mission. We knew that," Cook said.
