Denton Enterprise Airport, also known as Denton Airport and previously Denton Municipal Airport, is a city owned, public use airport located three nautical miles (6 km) west of the central business district of Denton, a city in Denton County, Texas, United States.This airport is assigned a three-letter location identifier of DTO by the Federal Aviation Administration, but it does not have an International Air Transport Association (IATA) airport code.HistoryThe airport was established in 1942 and used during 1943–44 by the United States Army Air Forces as a contract glider training airfield. It was known at the time as Denton Field. Harte Flying Service provided instruction. It was used primarily by C-47 Skytrains and Waco CG-4 unpowered Gliders. The mission of the school was to train glider pilot students in proficiency in operation of gliders in various types of towed and soaring flight, both day and night, and in servicing of gliders in the field.It was inactivated in late 1944 with the drawdown of AAFTC's pilot training program. It was then declared surplus and turned over to the Army Corps of Engineers on September 30, 1945. It was eventually discharged to the War Assets Administration (WAA) and became a civil airport in December 1946.
