Air Force Three is the air traffic control designated call sign held by any United States Air Force aircraft carrying the United States secretary of state, but not the president of the United States or vice president.[1][2][3] The term is often associated with the Boeing C-32, a modified 757 which is most commonly used as the secretary of state's transport.[4]
