what is an aircraft

aircraft is a vehicle which is able to fly supported by air. aircraft counters the gravity by forces called static lift ( balloons, blimps etc) or dynamic lift of an airfoil (wings and rotors). however, not all flying machines are considered as aircraft. eg. rockets and missiles. this because these two method of flying are not using aerodynamics force to fly, instead it uses rocket thrust, and only navigates by aerodynamics force. currently, the largest aircraft would be the Airbus A380 and the largest helicopter is the Mil Mi-26
