to provide logistical support for the expedition. Operation Deep Freeze I prepared a permanent research station and paved the way for more exhaustive research in later Deep Freeze operations. The expedition transpired over the Antarctic summer of November 1955 to April 1956, and was filmed by the U.S. Navy and Walt Disney Studios. For having designed the emblem of Task Force 43, Walt Disney became an honorary member of the expedition. Task Force 43 consisted of the following ships: , freighter , freighter , ice breaker , ice breaker , ice breaker , gasoline tanker , merchant marine freighter USS YOG-34, aviation fuel carrier USS YOG-70, aviation fuel carrier The ships of the task force were supplemented by a specially trained Navy Construction Battalion, formed at the Naval Construction Battalion Center at Davisville, Rhode Island and several aircraft. On 31 October 1956, Admiral Dufek and others successfully landed an R4D Skytrain (Douglas DC-3) aircraft at the South Pole, as part of the expeditions mounted for the IGY. This was the first aircraft to land at the South Pole and the first time that Americans had set foot on the South Pole. The aircraft was named Que Sera, Sera after a popular song and is now on display at the Naval Aviation Museum in Pensacola, Florida. This marked the beginning of the establishment of the first permanent base, by airlift, at the South Pole (today known as the Amundsen–Scott South Pole Station) to support the International Geophysical Year. It was commissioned on January 1, 1957. The original station ("Old Byrd") lasted about four years before it began to collapse under the snow. Construction of a second underground station in a nearby location began in 1960, and it was used until 1972. The station was then converted into a summer-only field camp until it was abandoned in 2004–05. The mission's second base, Byrd Station, was a (former) research station in West Antarctica established by the US Navy for Operation Deep Freeze II during the International Geophysical Year. The United States Antarctic Program airfield, built to service Operation Deep Freeze (first mission) was later named Williams Field or Willy Field. Subsequent developments The Operation Deep Freeze activities were succeeded by "Operation Deep Freeze II", and so on. In 1960, the year of the fifth mission, codenames began to be based on the year (e.g., "Operation Deep Freeze 60"). The Coast Guard sometimes participated;
