Flight's the process by which an object moves either through the air, or movement beyond earth's atmosphere (as in the case of spaceflight), by aerodynamically generating lift, propulsive thrust or aerostatically using buoyancy, or by simple ballistic movement. Types Buoyant flight Humans, although not apparently other animals, have managed to construct lighter than air vehicles that fly due to their buoyancy in air. Gliding versus powered flight Some things that fly aren't pushed forwards thr… (More on Flight)
