An aircraft is a machine that is able to fly by gaining support from the air‚ or‚ in general‚ the atmosphere of a planet. It counters the force of gravity by using either static lift or by using the dynamic lift of an airfoil‚[1] or in a few cases the downward thrust from jet engines. The human activity that surrounds aircraft is called aviation.
