94th Aero Squadron "Hat-in-the-Ring" Insignia

America's first combat squadron was the 94th. Its famous "Hat-in-the Ring" insignia reflected the phrase used in April 1917 when the United States entered the war and was said to have now "thrown its hat in the ring."

This example came from the aircraft of Harvey Weir Cook, who shot down 3 enemy aircraft and four observation balloons. The victories are represented with iron crosses inside the brim of the hat.
