McDonnell Douglas C-9
The McDonnell Douglas C-9 is a military version of the McDonnell Douglas DC-9 airliner. It was produced as the C-9A Nightingale for the United States Air Force, and the C-9B Skytrain II for the U.S. Navy and Marine Corps. The final flight of the C-9A Nightingale was in September 2005, and the C-9C was retired in September 2011. The U.S. Navy retired its last C-9B in July 2014. Two C-9Bs remain in service with the U.S. Marine Corps.

Design and developmentEdit
In 1966, the U.S. Air Force identified a need for an aeromedical transport aircraft and ordered C-9A Nightingale aircraft the following year. Deliveries began in 1968. The U.S. Air Force received 21 C-9A aircraft from 1968 to 1969. The C-9As were used for medical evacuation, passenger transportation, and special missions from 1968 to 2005. The C-9A were named for English social reformer Florence Nightingale (1820–1910), the founder of modern nursing.
After selecting a modified DC-9 for passenger and cargo transport, the U.S. Navy ordered its first five C-9Bs in April 1972. The Air Force in the early 1970s, under the Military Airlift Command was responsible for moving military personnel from place to place. The Navy documented to Congress that their people were being given last seating on Air Force flights. Congress authorized the Navy to fly its own passenger/cargo jets shortly thereafter. The C-9B aircraft have provided cargo and passenger transportation as well as forward deployed air logistics support for the Navy and Marine Corps. (The original "Skytrain" was the famous C-47 of the World War II era, developed from the civilian DC-3.) A C-9B was also chosen by NASA for reduced gravity research, replacing the aging KC-135 Vomit Comet.
Many of the Navy's C-9Bs had a higher maximum gross take-off weight of 114,000 lb (52,000 kg). Auxiliary fuel tanks were installed in the lower cargo hold to augment the aircraft's range to nearly 2,600 nautical miles (4,800 km) for overseas missions, along with the addition of tail mounted infrared scramblers to counter heat seeking missile threats in hostile environments.
- C-9A Nightingale - 21 aeromedical evacuation aircraft based on the DC-9-32CF for U.S. Air Force delivered during 1968–69. One was converted for executive transport and stationed at Chievres, Belgium; a second aircraft was converted for VIP transport by the 86th Airlift Wing at Ramstein Air Base.
- C-9B Skytrain II - 24 convertible passenger/transport versions for the U.S. Navy and Marine Corps delivered from 1973 to 1976. An additional 5 C-9s were converted from passenger configured DC-9s.
- VC-9C - 3 executive transport aircraft for the U.S. Air Force; these delivered in 1976.
- C-9K - 2 aircraft for the Kuwait Air Force.
There have been no class-a mishaps involving a C-9B, making it one of the safest aircraft in the Navy. The U.S. Air Force lost a single C-9A in a fatal crash that killed the three-man crew on a training flight in 1971 near Scott AFB.
