After retiring from NASA and the USAF in 1970, he became senior vice president for operations at Eastern Air Lines. He became chief executive officer of Eastern in 1975, and chairman of the board in 1976. Under his leadership, Eastern went through the four most profitable years in its history, but airline deregulation and additional debt that he took on to purchase new aircraft led to pay cuts and layoffs, and ultimately to conflict with unions, resulting in his resignation in 1986. He moved to Las Cruces, New Mexico, where he ran a Ford dealership with his son, Fred. In 1998, they bought a cattle ranch in Bighorn, Montana.
