Field in December 1945. Class 42-X gave 235 pilots their wings in an experimental course that sent pilot candidates directly to instructor training without first attending primary school, but though the course was considered a success, AAF Flying Training Command rejected its adoption. The Central Instructors School returned to Randolph in November 1945, was redesignated the AAF Pilot Instructors School, and relocated to Barksdale Field, Louisiana, on 12 March 1946. Like many military installations during World War II, Randolph fielded an intercollegiate football team, nicknamed the Randolph Field Ramblers. Under coach Frank Tritico, the 1943 team achieved a 9–1 record and was invited to play in the 1944 Cotton Bowl Classic, where they battled the Texas Longhorns to a 7–7 tie. The 1944 team, stocked with such stars as former All-American and National Football League (NFL) Rookie of the Year Bill Dudley and All-American running back Glenn Dobbs, as well as eight other former NFL players, went undefeated and untied in 11 games, and was ranked No. 3 in the nation by the AP Poll. The Army Air Forces also planned to return basic pilot training to Randolph on 1 February 1946. Even though basic training transferred from Goodfellow Field in February 1946, the Army Air Forces suspended all pilot training when it found itself with a shortfall of maintenance personnel. The U.S. Air Force became a separate service on 18 September 1947, and Randolph Field was officially renamed Randolph Air Force Base on 13 January 1948. When Randolph resumed flying training activities in March 1948, primary pilot training was deleted from its program, and in August 1948 the 3510th Pilot Training Wing (Basic) was activated. On 7 August 1950, during the Korean War, the 3511th Combat Crew Training Group was established as part of the 3510th PTW to train crews for the B-29 Superfortress, and the instructor pilot school was transferred to Craig Air Force Base, Alabama. On 11 June 1952 the pilot training wing was redesignated as the 3510th Flying Training Wing (Medium Bomber), and again in October 1954 (to reflect more accurately its actual mission) to the 3510th Combat Crew Training Wing. On 1 April 1952, the Air Force established the Crew Training Air Force (CTAF) with its headquarters at Randolph to administer nine bases and combat crew training wings, including the 3510th. B-29 training by the 3511th Flying Training Group (Medium Bomber) continued for five years,
