In this episode, we have Group Captain (ret.) Dr Paul Stewart on the show to talk about the development and importance of photo reconnaissance during the Second World War. Most people seem to known about the eccentric cryptographers working at Bletchley Park, but few people seem to be aware that another secret department, housed at RAF Medmenham from 1941, began producing thousands of intelligence reports that massively aided the Allied war effort. 

Dr Paul Stewart recently completed a PhD that examined RAF Medmenham's history, after a 35 year career as an RAF Intelligence Officer.
