Darren-- It is important for you, as you BEGIN your study, to understand that if your Grandmother is accurate, your Grandfather served in the 8th ARMY AIR FORCE.This is the MIGHTY EIGHTH.You should not confuse your thinking that this was a GROUND Army. The 8th AF was the largest single unit-designated employer in the American forces.So you have got to do a little detective work in your family records to narrow down the search for his particular unit within the 8th. As families get together for the holiday it might be a good time to chat with aunts and uncles and cousins to get a little info that will lead you on you search.Just finding out what kind of plane he was associated with will help a great deal.And a photo IS worth a thousand words.
Keep us posted and all questions you have will be answered! Happy Hunting!
