paper plane

Paper darts resembling modern paper planes were documented by the mid-19th century. Every Little Boy's Book, published in 1864, included instructions for folding a "paper dart" that curved through the air when thrown. Theodore von Kármán later recalled an occasion at a conference dinner in Delft when aerodynamicist Ludwig Prandtl, while explaining the mechanics of flight, folded a paper menu into a model aircraft; it landed on the shirtfront of the French Minister of Education.

• Illustration — Ninomiya's "N-424" design from Jet Age Jamboree (1966) Japanese engineer Yasuaki Ninomiya became prominent in paper-aircraft design after his models won the Pacific-region distance and duration categories of the First International Paper Airplane Contest in 1967. He later became the exclusive designer of AG Industries' Whitewings kits. Unlike simple folded planes, his designs used laminated paper components, and some kits were supplied with precut parts.

Paper-plane competitions include events for distance and time aloft.

Ken Blackburn set an indoor duration record of 27.6 seconds in October 1998. As of 2026 9, the Guinness World Record for the longest flight duration by a paper aircraft is 31.2 seconds. The record was achieved by Rao Chongyi, Wang Chenghao, Tang Shuai, Liu Liwen, Yang Shian, Jia Siyi and Pan Zichen in Kunshan, Jiangsu, China, on 11 February 2026.

Joe Ayoob, using an aircraft designed by John M. Collins, reached 69.14 m in 2012. Kim Kyu Tae reached 77.134 m in April 2022, and Dillon Ruble reached 88.31 m in December 2022. As of 2026 9, the record is 98.43 m (322 ft 11 in), achieved by Liu Liwen, with the support of Tang Shuai, Yang Shian, Huang Yizhou, Qiao Yuchen and Wang Chenghao, in Shanghai, China, on 28 December 2025. For the Guinness distance record, the aircraft must be flown indoors in a closed-air environment and constructed from a single sheet of A4 paper weighing less than 100 g/m 2. A thrower may take a walk or run-up of up to 10 ft, but must release the aircraft from a static position behind the throwing line.

Once released, a conventional paper plane is an unpowered glider. Its initial motion comes from the throw, after which its flight is governed principally by weight and the aerodynamic forces of lift and drag. NASA identifies paper planes as a familiar example of gliders that have no engines and therefore require an external source of energy to begin moving through the air. Paper planes operate in a relatively low-Reynolds number regime. A peer-reviewed aerodynamic study of a conventional dart design used water-tunnel flow visualization, force measurements and numerical simulation. It found that the dart's highly swept delta shape produced comparatively high lift coefficients at low Reynolds numbers, and identified the center fold as a feature that can improve aerodynamic performance.

In 2008, Japanese researchers tested a prototype paper plane in a wind tunnel while considering a release from the International Space Station. The project, involving Takuo Toda and University of Tokyo aerospace engineer Shinji Suzuki, was later postponed because of the difficulty of tracking the aircraft during their descent to Earth. In February 2011, a project released 200 paper planes from a net beneath a weather balloon about 23 mi above Germany. The planes carried memory chips, and organizers reported receiving recovery reports from several countries; a project spokesman expressed skepticism about some reports from the Southern Hemisphere. The Guinness World Record for the highest-altitude paper-plane launch is 35043 m, achieved by David Green in Elsworth, Cambridgeshire, United Kingdom, on 24 June 2015.
