Operation Crossroads Pin

"The atomic bomb that Rita Hayworth’s image allegedly adorned is the weapon detonated during the July 1, 1946 “Able” test on Bikini Atoll in the Marshall Islands. The bomb was dropped from a B-29 Superfortress airplane named “Dave’s Dream” and piloted by Major Woodrow P. “Woody” Swancutt. It was the fourth atomic bomb ever exploded and the first detonation ever to be reported on in real time by the media. The earlier bombs of Alamogordo, New Mexico (the Trinity test), Hiroshima and Nagasaki were, of course, top secret wartime affairs." - Bill Geerhart, Atomic Goddess: Rita Hayworth and the Legend of the Bikini Bombshell
