The C-9 Nightingale is the United States Air Force's modified version of the Douglas DC-9 airliner. It exists in two variants: the C-9A version is used for ferrying up to 40 medical evacuation patients, while the C-9C version is used to fly high-ranking bureaucrats around, kind of like a lesser Air Force One. The only way to tell the two apart is by looking for a big red cross on the tail, which tells you that you're looking at a C-9A.

There are currently 20 C-9A's in the Air Force, stationed at Scott AFB, Yokota Air Base, and Rammstein Air Base. All three C-9C's are stationed at Andrews AFB.
