Spyplane! This was apparently the first of several L-12s registered to Australian pilot Sidney Cotton and fitted with concealed cameras at Heston to photograph German military preparations on behalf of MI6. Cotton led the RAF's No 1 PDU (Photographic Development Unit) after the outbreak of the war. G-AFKR was sold to France in April 1939, becoming F-ARQA, and similarly used by aerial photographer Roger Henrard on behalf of the Deuxième Bureau. Photo by: Rudy Arnold / Smithsonian Institution
