The C-9A, which debuted in 1968, prepares for a mission at Scott Air Force Base, Ill. The Aircraft was the U.S. Air Force’s designated aeromedical evacuation aircraft that was capable of transporting more patients than previous aircraft. It was able to carry up to 40 patients, either litter or ambulatory, and was fitted with hydraulic folding ramps to easily move litter patients on and off the aircraft. (U.S. Air force photo)
