Fighter ace Lt. Frank Luke, a Phoenix native, gained fame in World War I as the "Arizona Balloon Buster" for his success against German observation balloons as well as enemy aircraft. Here he is with 13th confirmed kill. He was shot down and fatally wounded two months before the end of the war. German soldiers buried Luke in the Murvaux cemetery; Americans retrieved his body two months later. He received the Medal of Honor and Luke Air Force Base is named after him.
