INA, Ibaraki Pref. -- Before dawn on March 10, 1945, a U.S. B-29 bomber crashed into the woods outside a rural village some 45 km northeast of Tokyo.

Hidesaburo Kusama is joined by U.S. Air Force Col. Donald Weckhorst at the unveiling of a monument in Ina, Ibaraki Prefecture, for those who died in the crash of a U.S. bomber during World War II.

Hidesaburo Kusama, then 8 years old, had long wondered what happened to the three survivors of the crash he witnessed. Three years ago, he launched his own investigation into the case. He interviewed witnesses and examined government records, mainly from the United States.
