Norman E. Horn trained as a pilot at Love Field, Dallas, Texas, during World War I. No further biographical information is known.

Love Field was constructed near Dallas, Texas in response to the United States' entry into World War I, one of many airfields opened to train new pilots. A number of aero squadrons were stationed here as training squadrons, and were reassigned as lettered squadrons to denote their training status. These squadrons included the 71st Aero Squadron/Squadron "A" (February-November 1918), 121st Aero Squadron/Squadron "B" (April 1918-November 1918), 136th Aero Squadron/Squadron "C" (November 1917-November 1918), and 197th Aero Squadron/Squadron "D" (November 1917-November 1918). The 169th Aero Squadron, an observation squadron, was formed at Love Field in December 1917 and shipped overseas in February 1918. The 199th Aero Squadron (observation) was briefly stationed at Love in December 1917 before also continuing overseas. The 277th Aero Squadron, formed February 1918 at Love Field, made it as far as New York in August 1918 but never went overseas. Finally, the 865th Aero Squadron, a repair squadron, was formed at Love in March 1918 and subsequently assigned to a dedicated repair depot at the field.

Love Field was deactivated after the war and used primarily as storage for aircraft. In 1929, civilian use of the airfield began with passenger flights after the city of Dallas purchased the land. It continues to be operated as a Dallas, Texas area airport under the name Dallas Love Field.
