Photographic reconnaissance was of vital importance to the Allied war effort during WW2. The RAF's Photographic Unit ? the PRU ? operated from Benson airfield, near Oxford, with two squadrons each of Spitfires and Mosquitoes. The ?Mossie' was described by John Cunningham as ?the most outstanding aircraft developed during the Second World War'. Focus on Europe is the story of one young man who flew unarmed PRU mosquitoes on dangerous, but vital, reconnaissance sorties over Europe in 1943-5. Ron Foster came to the UK from New Zealand, and during that period he and his navigator flew sixty-nine sorties over every country in Europe except Greece and Portugal. AUTHOR: Ron Foster volunteered for service in the Royal New Zealand Air Force in early 1942. After training as a pilot he was selected to join the RAF Photographic Reconnaissance Unit based at Benson. 60 b/w photos
