UNITED KINGDOM - DECEMBER 17: Testing the engines of a Supermarine Rolls Testing the engines of a Supermarine Rolls Royce aeroplane, 11 August 1931. These trials are in preparation for the Schneider Trophy contest. The Schneider Trophy race was one of the earliest contests for pilots. Jacques Schneider, the sponsor of the race, instigated the first event in Monaco in 1913 with the intention of encouraging seaplane development. Twelve contests were held between 1913-1931 until Britain gained permanent possession of the trophy for winning three consecutive events in five years. Photograph by George Woodbine.
