USAAF historical organisations and associations
Many units – especially the combat groups will have at least one website dedicated to them online, a quick internet search should reveal this. Airfield museums also exist across the UK to perpetuate the history of US air power in their area.
Websites dedicated to units may carry detailed histories of the group and its squadrons, a roster of personnel, photographs, contacts, and copies of their association’s newsletter. These are brilliant sources for finding out further details.
Airfield Research Group houses collections from many Eighth Air Force Bomb and Fighter Groups, along with an archive on the First Air Division Headquarters.
