After graduating from Georgia Tech, Swindle reported to Marine Corps Base Quantico for The Basic School. He then reported to NAS Pensacola, Florida for initial flight training followed by follow-on training at other naval air stations. After earning his wings in May 1964, he was stationed at MCAS Beaufort, South Carolina. On February 1, 1966, he deployed with VMF-235 to DaNang Air Base and flew more than 200 sorties in the Vought F-8E Crusader during the Vietnam War. On November 11, 1966, Capt Swindle's Crusader was shot down while on a mission over the Quảng Bình Province, North Vietnam. It was his last scheduled flight. Captured by the North Vietnamese near the city of Vinh Linh, Capt Swindle spent the next seven years being shuffled around various prison camps, including the notorious Hanoi Hilton complex. While in captivity, he shared a cell with future senator and presidential candidate, then-Lieutenant Commander John McCain, USN. Promoted to the rank of major while in captivity, he was released on March 4, 1973. Restored to flying status, he then flew the A-4M Skyhawk II and TA-4F Skyhawk II at MCAS Cherry Point, North Carolina. He subsequently attended Florida State University under a Marine Corps-funded postgraduate program, earning a Master of Business Administration degree in 1975. He then returned to the Fleet Marine Force. His 20 military decorations for valor in combat include two Silver Stars, the Legion of Merit with Combat "V", two Bronze Stars with Combat "V", two Purple Hearts, two personal and eleven Strike/Flight awards of the Air Medal, the Navy Commendation Medal with Combat "V", the Combat Action Ribbon, the Prisoner of War Medal and numerous other unit, campaign and service awards. His non-combat decorations include a Gold Star in lieu of a second Legion of Merit and the Meritorious Service Medal. Swindle retired from the U.S. Marine Corps in 1979 with the rank of lieutenant colonel.
