WWII aircrew research advice request
My great-uncle was bomber crew in WWII. I'm sure I heard mention that he was a Nav, but I don't know this to be fact. He was lost on ops during the war, but other than that I know nothing else. I would like to know more, but there are no family members left to ask.
How do I go about finding out where he was stationed, on what squadron, what a/c, and details like that? I imagine that records must exist somewhere, but where?
How much information will I need before a result could be obtained?
Many thanks in advance.
I was unsure whether to post in AH&N or here, but as he was mil aircrew I thought here would be most appropriate.
Any advice would be gratefully received.
Cheers,
Nacluv
