On April 18, 1942, the U.S. launched the Doolittle Raid in retaliation to the Japanese attack on Pearl Harbor. American pilots taking part in the operation crash-landed in Quzhou, China, where they were rescued by local villagers. Even in their later years, the Doolittle Raiders never forgot the bond forged in Quzhou. In 2008, James, son of airman William Bower, who piloted Bomber No. 12, reached out to Quzhou researcher Zheng Weiyong on behalf of his elderly father, who wished to have a piece of his downed aircraft as a keepsake. So it was Zheng that eventually recovered a fragment of the plane and dispatched it to the U.S. – a heartfelt act of kindness and a legacy of friendship!
