Pan American Airways offered to fly designs of paper airplanes that originated in Japan to the contest. He entered and, out of 12,000 entries from 28 countries, won in two categories: duration and distance. [3] His designs have sold millions throughout Japan and the world. He is the author of a multi-volume work on high-performance paper ...
Time published an April 2, 1973 article, The Paper-Plane Caper, [2] about the paper airplane and its Kline–Fogleman airfoil. Also in 1973, CBS 60 Minutes did a 15-minute segment on the KF airfoil. CBS reran the show in 1976. [citation needed] In 1985, Kline wrote a book entitled The Ultimate Paper Airplane. [3]
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.
In these transonic speed ranges, compressibility causes a change in the density of the air around an airplane. During flight, a wing produces lift by accelerating the airflow over the upper surface. This accelerated air can, and does, reach supersonic speeds, even though the airplane itself may be flying at a subsonic airspeed (Mach number < 1.0

One of the biggest problems facing a paper-airplane is its lack of inertia and its very light wing loading due to its very low mass - so a paper airplane is incredibly susceptible to gusts, turbulence, drag due to cross-sectional area, and because it is so easy to turn over, a paper airplane is easily upset to unusual attitudes that are ...
United States Air Force F-15C Eagles flying in a Vic formation over Alaska. Formation flying is the flight of multiple objects in coordination. Formation flying occurs in nature among flying and gliding animals, and is also conducted in human aviation, often in military aviation and air shows.
At high-subsonic flight speeds, the local speed of the airflow can reach the speed of sound where the flow accelerates around the aircraft body and wings. The speed at which this development occurs varies from aircraft to aircraft and is known as the critical Mach number.
