Capt. Eddie Rickenbacker and 94th Aero Squadron Insignia Note: This item is currently in storage. Capt. Eddie Rickenbacker was the charismatic commander of the 94th Aero Squadron and was America’s highest scoring ace of World War I. The 94th Aero Squadron was known informally as the “Hat in the Ring Squadron,” a name that was inspired by their insignia. Rickenbacker was fond of the design, as he describes in his journal entry for April 12, 1918: “Have been busy all day painting squadron insignia on my plane. Ours is a most interesting one as we have Uncle Sam’s hat upside down in a ring with national colors -- it’s very good looking.” Click here to return to the Featured World War I Artifacts index.
