resulting in some minor cracking to the concrete surface. Operations included two weekly trips from Morrison Field to Albrook Field, Panama using Río Hato Army Air Base as an alternate field. In 1947, the 2nd and 3rd Air Transport Groups (Provisional) were formed and the C-74 was declared operationally ready. Humanitarian missions were flown in 1947 that included flood relief to Florida, and Hurricane relief for the southern area of the U.S. MATS operations Morrison Field was inactivated on 1 July 1947, and both provisional units were inactivated, the aircraft and support personnel and equipment being reassigned to Brookley Field, Alabama. On 1 June 1948, the Military Air Transport Service (MATS) was formed with the merging of the Air Force's Air Transport Command and the Navy's Naval Air Transport Service. Within MATS, all of the Globemasters were assigned to the Atlantic Division. Once in operational use, C-74s began to be used on scheduled MATS overseas routes through the late 1940s and mid-1950s: "Panamanian", between Brookley AFB, Alabama and Albrook AFB, Panama "Puerto Rican", between Brookley AFB and Ramey AFB, Puerto Rico "Hawaiian", between Brookley AFB and Hickam AFB, Hawaii, with a stop at Fairfield-Suisun (later Travis) AFB, California. "Johnathan", between Brookley AFB, Kelly AFB, Texas; McClellan AFB, California; McChord AFB, Washington, and Elmendorf AFB, Alaska. Brookley AFB and Casablanca-Anfa Airport, French Morocco; Wheelus Air Base, Libya Brookley AFB and Keflavik Airport, Iceland; RAF Manston, England. Additionally, logistic support flights for Strategic Air Command (SAC), and Tactical Air Command (TAC) saw the Globemaster in North Africa, the Middle East, Europe, the Caribbean, and within the United States. Two C-74s were used to support the first TAC Republic F-84 Thunderjet flight across the Pacific Ocean to Japan. SAC also continued to use the Globemasters to rotate Boeing B-47 Stratojet Medium Bombardment Groups on temporary duty in England and Morocco as part of their REFLEX operation. Berlin Airlift During the Berlin Airlift, a single Globemaster (42-65414) arrived at Rhein-Main Air Base on 14 August 1948 and landed for the first time on 17 August at Berlin's Gatow Airfield in the British sector carrying 20 tons of flour. Over the next six weeks, the Globemaster crew flew 24 missions into the city delivering of supplies. Several airlift records were set by the crew in 414 during Operation Vittles. On 18 September, Air Force Day, the crew flew six round trips into Berlin hauling a
