Photo taken on April 19, 2019 shows the sole upright goblet, engraved with the name Richard E. Cole, at the National Museum of the U.S. Air Force in Dayton, Ohio, the United States. Seventy-nine silver goblets have been symbolically turned upside down, leaving only one, engraved with the name Richard E. Cole, standing upright. All shine behind show windows in the largest military museum in the world as a silent homage commemorating 80 heroic Doolittle Raiders who launched America's first airstrike on Tokyo during WWII.
