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 birds, bats and 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 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.

Famous quotes containing the word flight:
“Sure smokers have made personal choices. And they pay for those choices every day, whether sitting through an airline flight dying for a smoke, or dying for a smoke in the oncology wing of a hospital. The tobacco companies have not paid nearly enough for the killing.”
—Anna Quindlen (b. 1952)
“No Ravens wing can stretch the flight so far
As the torn bandrols of Napoleons war.
Choose then your climate, fix your best abode,
Hell make you deserts and hell bring you blood.
How could you fear a dearth? have not mankind,
Tho slain by millions, millions left behind?
Has not conscription still the power to weild
Her annual faulchion oer the human field?
A faithful harvester!”
—Joel Barlow (17541812)
“When the flight is not high the fall is not heavy.”
