How One “Impossible” Bouncing Bomb Blew Open Germany’s Ruhr Dams

A source-grounded account of Operation Chastise—the night 617 Squadron flew Lancasters at sixty feet to bounce Barnes Wallis’s back-spinning “Upkeep” bombs across reservoir surfaces, jump anti-torpedo nets, cling to the Möhne and Eder dam walls, and detonate where water could tear masonry. We unpack the physics (backspin, hydrostatic fuses, detonation depth), the simple but ruthless geometry of crossed-spotlight altimetry and range sights, and the training that made low-level precision a craft. The raid’s consequences—breaches, floods, rapid German repairs, and shifted priorities—are weighed without romance: leverage, not magic. From test ranges to doctrine, the story traces how a prototype flown at the edge of the possible became a template for later precision strikes and “earthquake” weapons. It’s a study in how discipline and nerve can make physics into strategy.
