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.
Bomber Command
The air attacks on Japan included the most devastating single air raid in history. It was not, as some might think, the result of dropping the atomic bombs on Hiroshima and Nagasaki. It was a firebombing of Tokyo on the night of 9–10 March 1945, which created a conflagration and killed 100,000 people and destroyed 16 square miles of the city, far more damage and deaths than either the atomic bombing of Hiroshima or of Nagasaki.
