I'm not an expert in Disney history, but most people know the company helped America's war effort in World War II by designing logos for units, and making training films. At work, I've stumbled across this pre-war (to America at least) example of the Naval Air Station Pensacola Florida yearbook
The Flight Jacket 1940, which was compiled for the training class for new pilots. At some point in the next few months, the yearbook will be transferred to the more appropriate
Navy Department Library in the Washington Navy Yard which appears to need a copy. In the meantime, one can see scans of the
famed Duck here.
