Although the dispersal of flying units under the Detached Squadron Concept was not a problem when the entire wing was called to active service, mobilizing a single flying squadron and elements to support it proved difficult. This weakness was demonstrated in the partial mobilization of reserve units during the Berlin Crisis of 1961. The 77th and 78th Troop Carrier Squadrons converted to the Douglas C-124 Globemaster II in 1961, and were ordered to active service for the crisis, although the 76th Troop Carrier Squadron, which continued to fly the C-119, remained in reserve status. After training to become combat ready, the mobilized wing participated in worldwide airlift and tactical exercises. The wing returned to reserve status in August 1962 and the 76th Squadron was once more assigned.
