Flight is the process by which an object (physics) achieves sustained movement either through the air by aerodynamically generating Lift (force) or Lighter than air using buoyancy, or movement beyond earth's atmosphere, in the case of spaceflight.

Animal flight

The most successful groups of Flying and gliding animals are insects, birds, and bats. Each of these groups' wings evolution Convergent evolution from different structures. See also Bird flight. Also successful were the extinct Pterosaurs, an Order (biology) of reptiles contemporaneous with the dinosaurs.

Bats are the only mammals capable of true flight. However, there are several Flying squirrel which are able to glide from tree to tree using fleshy membranes between their limbs; some can travel hundreds of meters in this way with very little loss in height. Flying tree frogs use greatly enlarged webbed feet for a similar purpose, and there are Draco blanfordiis which employ their unusually wide, flattened rib-cages to the same end. Certain snakes also use a flattened rib-cage to fly, with a back and forth motion much the same as they use on the ground.

Flying fish can glide using enlarged wing-like fins, and have been observed soaring for hundreds of meters using the updraft on the leading edges of waves. It is thought that this ability was chosen by natural selection because it was an effective means of escape from underwater predators.

Most birds fly (see bird flight), with some exceptions. The largest birds, the ostrich and the emu, are earthbound, as were the now-extinct dodos, while the non-flying penguins have adapted their wings for use under water. Most small flightless birds are native to small islands, and lead a lifestyle where flight would confer little advantage. The Peregrine Falcon is the fastest animal in the world; its terminal velocity exceeds 370 km/h (199 Miles per hour) in a dive.

Among living animals that fly, the wandering albatross has the greatest wingspan, up to 3.5 meters (11.5 feet); the great bustard has the greatest weight, topping at 21 kilograms (46 pounds)http://www.trumpeterswansociety.org/id.htm.

Among the many species of insects, some fly and others do not (See insect flight).

==Mechanical flight==

Mechanical flight is the use of a machine, called an aircraft, to fly. These machines include kites, helicopters, autogyros, airships, balloon (aircraft)s, and spacecraft. Gliders provide unpowered flight. Another form of mechanical flight is parasailing. This occurs by a parachute like object being pulled by a boat.

The most common form of mechanical flight is aeroplane flight. Several steps are involved:

Flight planning,
Taxiing,
Take off,
Climbing,
Cruise (flight),
Loiter (flight)
Descent (aircraft), and
Landing.

See aviation history and First flying machine for the history of mechanical flight.

Physics Several forces are particularly important for flight:

Air propulsion: (except in gliders)
Lift (force): Created by wings
Drag (physics): Created by airflow
Weight: (created by gravity)
Buoyancy: for lighter than air flight

==In fiction==In fiction, particularly fantasy, science fiction and comic books, many characters have the ability to fly without a vehicle, often attributed to supernatural or paranormal explanations.

In Greek mythology Daedalus, the legendary Athenian craftsman and inventor, made wings for himself and his son Icarus out of wax and feathers to escape from King Minos of Crete. They flew away, but Icarus flew too near the sun. The wax of his wings melted and he fell into the sea and was drowned. Daedalus landed on the island of Aegean Sea (now known as Ikaria) and buried his son's body.
Dumbo, the The Walt Disney Company-created elephant, employs his comically oversized ears as wings for flight.
Charles M. Schulz's legendary cartoon dog Snoopy can fly by spinning his ears extremely fast above his head like a helicopter, or as he calls it, a whirlydog.
Western dragons are depicted with wings.
Superman is a superhero in comic books, cartoons, and films; flight is among the various superpowers he is portrayed to obtain from the yellow rays of Earth's sun. Most fictional comic book superheroes are said to fly by willpower or by telekinetically Levitation themselves. Jean Grey of the X-Men, for example, uses telekinesis to levitate above ground. Storm (Marvel Comics) of the X-Men flies by controlling the weather in her immediate vicinity. Magneto (comics) flies by magnetically polarizing the high electrolyte content in his blood against the Earth's (or the largest in proximity) natural magnetic field. Apocalypse (comics) can grant himself flight by morphing his arms into wings or jets. Also, some superheroes have wings, rather than willpower. For example, Archangel (comics) from the X-Men flies thanks to two feathery wings that come out of his back.
In the 1995 film Slam Dunk Ernest, Jim Varney trademark character is granted the gift of flight by Kareem Abdul-Jabbar.
Santa Claus has a sleigh pulled by flying reindeer.
In the Hitchhiker's Guide to the Galaxy books, Arthur Dent accomplishes flight by throwing himself at the ground and missing.
Pegasus was a winged horse in Greek mythology who appears in, among other things, the 1980s film Clash of the Titans.
In Bionicle storyline, a Kanohi mask called Kadin allows the user the ability to fly.
In the popular Dragon Ball metaseries, Son Goku (Dragon Ball) and the other Z Fighters achieve the ability to fly by controlling and manipulating their chi energy.
In the television series Heroes (TV Series) one of the main characters, Nathan Petrelli, has the capability to fly. His brother Peter Petrelli was able to absorb this ability and reproduced it.
Miles "Tails" Prower from Sonic the Hedgehog (series) uses his two tails to propel himself and maintain temporary flight over short distances. Other fictional characters from this universe, like Rouge the Bat and Cream the Rabbit, can also fly.
