Then I was 18 and so I was due for call-up, national service; everyone had to do two years national service and I applied to the RAF to be a photographer, and I was quite lucky; I got into the section to train to be a photographer and spent... I think it was 16 weeks training at a place called Wellsbourne Mountford, and then I moved onto a place in Oxford called Nuneham Park, which is... was a subsidiary to Benson. Benson was an aerodrome with a photographic establishment and Nuneham Park was a few miles away, where we did all the printing for the aerial survey work. So we had these wide bands of film that would... would come in and we'd have to print them and then make up the maps for the aerial survey... on to surveys, so it... it was kind of keeping in touch with, in a way with things that I'd had before and also taking still photographs, and it was a very happy time, particularly because I made some very good friends; Sandy Rawlingson who now lives in Australia and Tony Moore who went to live in Canada and... and John Jochimsen whom I'd met at the Colonial Film Unit just before I went to Africa and he was also in the RAF as a photographer.
