Front and back covers of the official Royal aero Club souvenir programme. The front cover features a seaplane in flight, whilst the back cover shows the Vickers Supermarine S6B, powered by a Rolls Royce 'R' engine, that won the Schneider Trophy in 1931. Designed by Reginald Mitchell, the S6B led to the development of his now more famous 'Spitfire' aeroplane. Instigated by Jacques Schneider, the Trophy was awarded to the fastest and most seaworthy plane between 1913 and 1931. The event was always keenly fought and led to many pioneering innovations in aircraft design and engine power. Twelve contests were held between 1913-1931 in England, Italy, France and the United States. Britain kept the trophy permanently after winning it for the third time in 1931.
