:This article concerns the process of flying. For other meanings see Flight (disambig).

Flight is the process of flying: either movement through the air by aerodynamically generating lift or

aerostatic ally using buoyancy, or movement beyond Earth's atmosphere by spacecraft.

1 Animal flight


The most successful groups of living things that fly are insects, birds, and bats. Each of these groups' wings evolved separately from different structures.

Pterosaurs were a group of flying vertebrates contemporaneous with the dinosaurs.

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

Flying fish can glide using enlarged wing-like fins, and have been observed soaring for hundreds of metres using the updraft on the leading edges of waves. It is thought that they evolved this ability to help them escape from underwater predators.

Most birds fly, with some exceptions. The largest birds, the ostrich and the emuDromaius novaehollandiae ''Dromaius baudinianus (extinct) Dromaius ater (extinct) The Emu Dromaius novaehollandiae which, in Latin, means "fast-footed New Hollander", referring to Australia, whose old name was New Holland) is the largest bird native to Au, are earthbound, as were the now-extinct dodoThis article is about the extinct bird.

For other meanings, see Penguin (disambiguation). Aptenodytes Eudyptes Eudyptula Megadyptes Pygoscelis Spheniscus Penguins (order Sphenisciformes family Spheniscidae are an order of flightless birds living in the souths have adapted their wings for use under water. Most small flightless birds are native to small islands, and lead a lifestyle where flight confers little advantage.

Among the millions of species of insects, many do not fly.

Among living animals that fly, the wandering albatross has the greatest wingspan, up to 3.5 metres (11.5 feet), and the trumpeter swan perhaps the greatest weight, 17 kilograms (38 pounds).

2 Mechanical flight

Flying machines are aircraftThis article refers to the tool of travel. There is a separate article about the movie Airplane An aircraft is any machine capable of atmospheric flight. Categories and clasification Aircraft fall into two broad categories: Heavier than air Heavier than a, including aeroplanes, helicopters, airships and balloons, and spacecraft.
