The film is a reminder of not only the scientific and technological miracle that was made possible by the Manhattan Project, which developed the atomic bombs that ended World War II, but also of what did not happen – namely, the massive ground invasion of the Japanese home islands that was being planned. Although it all transpired before I was born, I have several connections to it.
The Manhattan Project to develop the bombs was one of the greatest scientific, technological, and logistical achievements in history. The bombs ended the war and saved millions of lives of combatants and civilians.
