Tadayoshi Koga was the pilot. He was a 19-year-old flight petty officer first class. He launched from the Japanese aircraft carrier Ryūjō as part of a June 4 1942 raid on Dutch Harbor, Alaska. Small gun fire cut the oil line in the plane. Without oil, the plane crashed and killed the pilot. The plane did not break apart in the crash. The pilots of other Zero planes flying with Koga thought that he might be alive. Because of this, they did not try to destroy his plane. The Americans got the plane in July.
