While Capt. Harmon met an untimely death in an aviation accident in 1933, he is credited with having recruited, and mentored the careers of many individuals who went on to become heroes, and leaders in the United States military. In 1924, Harmon saw promise in a young University of Maryland football quarterback named Pete Quesada. Harmon took Quesada flying out of Bolling Field in Washington D.C. and successfully recruited him on the same day into the Army Air Service. Harmon, himself a former football player at Bethany College, West Virginia, had an ulterior motive in recruiting Quesada into the Air Service. It was to include Quesada on the Air Service football team at Kelly Field in San Antonio, Texas while he was in flight training. Later in his career, Gen. Pete Quesada, and his Ninth Air Tactical Command, led the air invasion on D-Day (June 6, 1944 aka "Overlord") during World War II. Lt. Gen Pete Quesada is widely recognized as having developed the strategy of proving the successful use of tactical "close air support" to ground troops during combat.
