The bouncing bomb of the famous "Dambusters Raid" did not end with Operation Chastise over the Mohne, Sorpe and Eder dams. The revolutionary concept was refined and miniaturised to suit Mosquito fighter bombers. The idea was for these fast twin-engined aircraft to replace torpedos with the bouncing bomb in raids against the surviving capital ships of the Japanese fleet in their heavily protected anchorages. But the mission - on the brink of being launched - was cancelled in August 1945 with the deployment of the atomic bombs against Nagasaki and Hiroshima.
Here, designers and engineers involved with the project describe the evolution of the bomb - and their experiences with their "inhuman" project leader - Barnes Wallis.
