Someone [posted](https://poal.co/s/HiddenHistory/759914) about the code word they used for a successful hit on the dam. From Wikipedia: > The Dam Busters is a 1955 British epic docudrama war film starring Richard Todd and Michael Redgrave, that was directed by Michael Anderson. Adapted by R. C. Sherriff from the books The Dam Busters (1951) by Paul Brickhill and Enemy Coast Ahead (1946) by Guy Gibson, the film depicts the true story of Operation Chastise when in 1943 the RAF's 617 Squadron attacked the Möhne, Eder, and Sorpe dams in Nazi Germany with Barnes Wallis's bouncing bomb. … > Gibson's black Labrador, Nigger, whose name was used as a single codeword whose transmission conveyed that the Möhne Dam had been breached, is portrayed in several scenes; his name and the codeword are mentioned fourteen times. …. > Gibson's dog, Nigger, is depicted being killed on the day of the raid; Nigger actually died the day before. The correct name of the dog is frequently changed in television reruns of the film when it is broadcast. I haven’t seen this movie, but I’ve heard of the bouncing bomb technique and any movie that used the real code word must be at least half decent.
