aircraft

n. any vehicle which can be flown through the air (i.e. airplane or helicopter)

An aircraft is a vehicle which is able to fly through the air (or through any other atmosphere). All the human activity which surrounds aircraft is called aviation. (Most rocket vehicles are not aircraft because they are not supported by the surrounding air).Manned aircraft are flown by a pilot. Unmanned aircraft are traditionally called drones, while the term RPV (remote piloted vehicle) has recently become common in modern military circles.
