McCain underwent treatment for his injuries that included months of physical therapy. He attended the National War College at Fort McNair in Washington, D.C. during 1973–1974. He was rehabilitated by late 1974, and his flight status was reinstated. In 1976, he became Commanding Officer of a training squadron that was stationed in Florida. He improved the unit's flight readiness and safety records, and won the squadron its first-ever Meritorious Unit Commendation. During this period in Florida, he had extramarital affairs, and his marriage began to falter, about which he later stated: "The blame was entirely mine".
