'''Flight''' is the [[process]] by which an object moves, through an [[atmosphere]] (especially the [[air]]) or beyond it (as in the case of spaceflight), by generating aerodynamic lift, [[propulsive]] thrust, aerostatically using [[buoyancy]], or by ballistic movement, without direct [[support]] from any [[surface]].

Many things fly, from natural aviators such as [http://en.wikipedia.org/wiki/Bird birds], [http://en.wikipedia.org/wiki/Bat bats] and [http://en.wikipedia.org/wiki/Insect insects] to human [[inventions]] such as missiles, aircraft such as airplanes, helicopters and balloons, to rockets such as spacecraft.

The engineering aspects of flight are studied in [http://en.wikipedia.org/wiki/Aerospace_engineering aerospace engineering] which is subdivided into aeronautics, the [[study]] of vehicles that travel through the air, and astronautics, the study of vehicles that travel through [[space]], and in ballistics, the study of the flight of projectiles.
