The Brooklands contribution to the Royal Air Force's legendary 617 Squadron 'Dambusters' attack on Germany's Ruhr Valley reservoirs on 16–17 May 1943 was commemorated on 12 May 2013 by three impressive flypasts of Brooklands Museum given by the RAF Battle of Britain Memorial Flight's Avro Lancaster – as a special 70th anniversary tribute to Barnes Wallis and the Vickers-Armstrongs design and experimental department engineers who made the 'Upkeep' mine such a successful weapon.
