==Origin==
[http://nordan.daynal.org/wiki/index.php?title=English#ca._1100-1500_.09THE_MIDDLE_ENGLISH_PERIOD Middle English], from [http://nordan.daynal.org/wiki/index.php?title=English#ca._600-1100.09THE_OLD_ENGLISH.2C_OR_ANGLO-SAXON_PERIOD Old English] ''flyht''; akin to Middle Dutch ''vlucht'' flight, Old English ''flēogan'' to fly
*[http://en.wikipedia.org/wiki/12th_century before 12th Century]
==Definitions==
*1a : an act or instance of passing through the [[air]] by the use of wings <the flight of a bee>
:b : the [[ability]] to fly <flight is natural to birds>
*2a : a passing through the air or through [[space]] outside the earth's [[atmosphere]]
:b : the distance covered in such a flight
:c : swift movement
*3a : a trip made by or in an airplane or spacecraft
:b : a scheduled airplane trip
*4: a group of similar [[beings]] or objects flying through the air together
*5: a [[brilliant]], [[imaginative]], or unrestrained [[exercise]] or display <a flight of fancy>

==Description==
'''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.
