The Vickers Wellington was the RAF's primary heavy bomber at the outbreak of war in 1939, and its survival into the mid-war years owed almost entirely to the geodetic airframe construction developed by Barnes Wallis — the same engineer who later designed the bouncing bomb used in the Dambusters raid. That basket-weave fuselage could absorb catastrophic damage and still bring crews home. The Isle of Man Treasury issued a long-running series of aviation crowns through the 1990s commemorating British aircraft, with this 1995 silver proof among the more technically interesting subjects in that run.
