Lieutenant Frank Kerr Hays was a World War I flying ace credited with six aerial victories. He was living in Chicago when he decided to join the U.S. Army Air Service. He reported to the 13th Aero Squadron on 29 August 1918. On 13 September, he won his first three victories in a melee in which he continued his attack after his guns jammed. He cleared them in time to rescue his Flight Commander from enemy attack. The feat was good for a DFC. He would score three more times, his last win coming one week before the armistice ended the war.
