401st Bomb Group Unit History, complete copy Many of the 8th Air Force Groups produced an unofficial unit history in the months after the war ended in Europe but before they were redeployed out of the ETO (‘European Theater of Operations’). The Duxford Diary was the book created by and for the service personnel who were based at Duxford at the end of the war in Europe, as a memento of their time at the airfield. Resembling a college yearbook, unit histories were an unofficial – and often tongue-in-cheek – record of the unit’s time in the UK. They include photo montages showing different aspects of base life. Often the servicemen in the photos are unnamed. The American Air Museum hopes that by adding unit histories to the website as individual pages, the men in the photos will be identified and associated to their person entries.
