Dam Busters

[David_Hayward (RIP)]

The Germans recovered an unexploded mine after the raid and presumably made it safe

The unexploded mine that overshot was indeed found, made safe and then blueprinted ['reverse engineering' as we would now call it] and then the Germans came up with their own version.

Of course 'we' did the same with the V-1 to create the 'Loon'. If the quantity and required supplies of cordite required to launch the 'Loon' in the absence of Hydrogen Peroxide to the quality that the Germans could produce, could have been sorted we would have fired thousands of V-1 clones back across the Channel!
