aircraft any machine capable of flying by means of buoyancy or aerodynamic forces, such as a glider, helicopter, or aeroplane www.aerospaceweb.org/aircraft/index.shtml Aircraft Any vehicle which carries one or more persons and which navigates through the air. The two main classifications of aircraft are lighter-than-air and heavier-than-air. The term lighter-than-air is applied to all aircraft which sustain their weight by displacing an equal weight of air, for example, blimps and dirigibles. Heavier-than-air craft are supported by giving the surrounding air a momentum in the downward direction equal to the weight of the aircraft.
