At the same time, the Air Force began detaching Air Force Reserve squadrons from their parent wing locations to separate sites. The concept offered several advantages: communities were more likely to accept the smaller squadrons than the large wings and the location of separate squadrons in smaller population centers would facilitate recruiting and manning. As it finally evolved in the spring of 1955, the Continental Air Command's plan called for placing Air Force Reserve units at fifty-nine installations located throughout the United States. Under this plan, although the 704th and 705th Troop Carrier Squadrons were located with the wing at Ellington, its 706th Troop Carrier Squadron was stationed at Donaldson Air Force Base, South Carolina.
