On the night of the 16th May, 1943, Operation Chastise commenced - 133 RAF airmen in their iconic Lancaster bombers took off from England, bound for Germany. Armed with specially designed 'bouncing bombs', the highly trained crews were tasked with destroying key installations in Germany's industrial heartland, the Ruhr Valley. It was an audacious mission of unprecedented precision, from which over a third of the airmen would never return. The Dambusters Raid, as it came to be known, is remembered as one of the greatest feats of daring and airmanship in the Second World War. In this two-part Explainer, and with the help of the late, great RAF veteran 'Johnny' Johnson, Dan delves into the true story of this historic operation.

Produced by James Hickmann and edited by Dougal Patmore.
