Borman returned to the United States, where he became a jet instrument flight instructor at Moody Air Force Base in Georgia, mainly in the T-33. In 1955, he secured a transfer to Luke Air Force Base. Most of his flying was in F-80s, F-84s, swept-wing F-84Fs and T-33s. In 1956, he received orders to join the faculty at West Point, after first completing a master's degree in aeronautical engineering. Not wanting to spend two years qualifying for a non-flying posting that could last for another three years, he searched for a master's degree course that took only one year, and settled on the one at the California Institute of Technology. He received his Master of Science degree in aeronautical engineering in June 1957, and then became an assistant professor of thermodynamics and fluid mechanics at West Point, where he served until 1960. He found he enjoyed teaching, and was still able to fly a T-33 from Stewart Air Force Base on weekends. One summer he also attended the USAF Survival School at Stead Air Force Base in Nevada.
