A simple folded paper plane Folding instructions for a traditional paper dart. A paper plane (also known as a paper airplane or paper dart in American English, or paper aeroplane in British English) is a toy aircraft, usually a glider, made out of a single folded sheet of paper or paperboard.
A paper plane, paper aeroplane (UK), paper airplane (US), paper glider, paper dart or dart is a toy aircraft (usually a glider) made out of paper or paperboard; the practice of constructing paper planes is sometimes referred to as aerogami (Japanese: kamihikÅki), after origami, the Japanese art of paper folding.

Paper airplanes are fun and simple for all ages. Paper airplanes can be made in five easy steps. Start by folding a piece of paper in half vertically.
Examples of soaring flight by birds are the use of: Thermals and convergences by raptors such as vultures; Ridge lift by gulls near cliffs; Wave lift by migrating birds [33] Dynamic effects near the surface of the sea by albatrosses; For humans, soaring is the basis for three air sports: gliding, hang gliding and paragliding.
During the last years of the previous century he had begun the first rigorous study of the physics of flight and would later design the first modern heavier-than-air craft. Among his many achievements, his most important contributions to aeronautics include: Clarifying our ideas and laying down the principles of heavier-than-air flight.
Person flying a Walkalong glider by controllable-slope soaring. Controllable-slope soaring (also known as Walkalong gliding) is a type of slope soaring where a slope is made to follow a walkalong glider (a lightweight toy aircraft), both sustaining and controlling the glider's trajectory by modifying the wind in the vicinity of the airplane.
Gliding is a recreational activity and competitive air sport [1] in which pilots fly unpowered aircraft known as gliders or sailplanes using naturally occurring currents of rising air in the atmosphere to remain airborne.
