The Sioux Falls Regional Airport, was established in 1939 with a Works Progress Administration grant of $165,000. Soon three runways were constructed, along with a terminal building, and a hangar. There was an unsuccessful movement to name the airport "Tennant Field" in memory of World War 1 veteran pilot and early Sioux Falls aviator Harold Tennant.
