DJFish1,
Welcome sir to a thread that knows no bounds, I'm sure Danny, our incumbent "senior man" will be along shortly to welcome you aboard. Your post has hit the bullseye in my opinion and any further information on your great uncle's experiences through training and operations, certainly log book extracts, would fit very nicely with the intent of this thread. As a coincidence, my father in law finished his war service as Groundcrew on 617 Squadron, and may have come in to contact with your great uncle. Post all you have, there are many here who will read, assimilate, and perhaps even open new lines of information to you.
