My father, Fred Jones, was a pilot in Bomber Command. He was in 44 Squadron. He was shot down over Germany in May 1940 and spent the rest of the war as a POW. He escaped three times but was re-captured on each occasion. He wrote coded letters back to a friend in London; he thought that this was the reason for him being able to continue as a pilot after the war. He left the RAF in 1959 when he got married and then ran his own business. He lived a long life and died after a very brief illness at the age of 90. I have his pilot’s log books (all in beautful copperplate). I’ve done some of my own research, including going to the National Archives in Kew a few years ago, where I found a questionnaire that he filled out when he was on his way home from Germany.
