On this day in 1942, a group working in Chicago and led by Enrico Fermi started the first man-made sustained nuclear chain reaction, and also stopped it. This controlled reaction did not itself release significant power. It did however show that controlled nuclear chain reactions were possible and that parts of the Manhattan Project could proceed. The title of this post was the code message sent to indicate the successful operation.
