Over the weekend of September 18th/19th the Imperial War Museum at staged a Battle of Britain air show at their facility in Duxford, Cambridge, the last major show of the year at the former RAF Duxford. The weather conditions varied significantly over the two days from bright sunlight to dull and hazy, but luckily the predicted rain failed to arrive. As might be expected for an air show with 'Battle of Britain' in its title, the event's primary emphasis focused upon the two classic Royal Air Force fighters of that period, the Supermarine Spitfire and Hawker Hurricane. While four different Hawker Hurricane Mk.Is took part in the weekend show, a total of 17 different Spitfires participated, representing nine different marques - from the Merlin-powered Mk.I to the Griffon-powered Mk.XIV.
