| '''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]]. | | '''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]]. |
