He later attended the University of Cambridge from 1952 to 1955, where he was a member of Gonville and Caius College, and earned a Master of Science degree. During his studies, he published several papers: in the Journal of the Royal Aeronautical Society, "Viscous effects on Pitot tubes at low speeds"; in the Aeronautical Journal, "Viscous effects on flattened Pitot tubes at low speeds"; and in the Journal of Scientific Instruments, "Liquid manometers with high sensitivity and small time-lag". Following completion of his degree, Macmillan returned to Canada and took employment helping development of the AIM-7 Sparrow. By the early 1960s he had left the aeronautical industry and moved to British Columbia where he began working in the pulp and paper sector.
