I was very interested to read your fathers service record. In WW2 the DFM was much harder to win than the DFC. I have two wartime DFMs in my family both with Bomber Command. It's great to know that some of these aviators are still with us and I wish your father a very happy birthday and many returns. Both of my uncles have passed on, but the wife of one still lives on at a healthy 103.
If you need any information on the Citations, Archimedes on this forum was very helpful to me.
