The C-9 Nightingales, which were used exclusively for MEDEVAC flights, were retired several years ago. However, the MEDEVAC missions continue. Today, the MEDEVAC mission is accomplished by using a variety of wide-bodied aircraft such as the C-17, C-130, and occasionally C-5 aircraft. Removable MEDEVAC litter and ambulatory pallets are used and may be placed by a forklift into the aircraft being used for air evacuation. Their flight schedules are based on need by military commands around the world. They are not flying on a routine schedule as in the days of the C-9 Nightingales. You may occasionally still find yourself traveling Space-A on a flight with passengers being air-evacuated, only the aircraft and methods of transport have changed.
