Operation Crossroads
There were only seven nuclear bombs in existence in July 1946. The two bombs used in the test were Fat Man plutonium implosion-type nuclear weapons of the kind dropped on Nagasaki. The "Able" bomb was stenciled with the name "Gilda" and decorated with an "Esquire" magazine photograph of Rita Hayworth, star of the 1946 movie, "Gilda". The "Baker" bomb was "Helen of Bikini." This femme-fatale theme for nuclear weapons, combining seduction and destruction, is epitomized by the use in all languages, starting in 1946, of "bikini" as the name for a woman's two-piece bathing suit.
First Into Nagasaki
On April 27, 1945, Lieut. Gene Flewellen commanding the B-29 "Experiment Perilous" was forced by weather to abandon his original target on Kyūshū and, without accompanying aircraft, flew southward down the coast seeking a target of opportunity and bombed the Nagasaki dock area. The absence of anti-aircraft fire indicated that the Japanese were "entirely surprised. The lone B-29 wheeled and headed south. Several hours later the pilot put the huge craft down at Saipan, with ten minutes of gas left in his tanks."
