hello, I am hoping someone can help or point me in the right direction please. I am researching my family and we have a mystery to solve. I believe my grandfather was in raf 129, his name was flynn and was something to do with the mustang aircraft. He was american of irish descent and was in Orkney in 1941, but I can only find records of 129 there in 1942. Where can I find more information, such as the members of the squadrons names?
