Category:Aircraft

An aircraft is a vehicle 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, or in a few cases the downward thrust from jet engines. They are unable to leave the atmosphere of a planet. Vehicles that can operate both in and out of atmospheres are known as aerospacecraft.
