Bouncing Bomb Tests
From December and into early January 1943 testing was carried out using metal spheres dropped from a Wellington Bomber at Chesil in Dorset. However they were being badly damaged when they hit the water rather than bouncing across the surface.
With these problems in mind Vickers produced this plan for a wooden version to be used for testing. The first successful release on Saturday 23 January resulted in the wooden test sphere bouncing 13 times.
