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.

Blackburn's record-breaking 20-year-old paper plane [14] was based on his belief that the best planes had short wings and are "heavy" at the point of the launch phase in which the thrower throws the paper plane into the air, and at the same time longer wings and a "lighter" weight would allow the paper plane to have better flight times but this ...
However, gliding can be achieved with a flat wing, as with a simple paper plane, [2] or even with card-throwing. However, some aircraft with lifting bodies and animals such as the flying snake can achieve gliding flight without any wings by creating a flattened surface underneath.

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]
An emergency slide fell off a Delta Air Lines jetliner shortly after takeoff Friday from New York, and pilots who felt a vibration in the plane circled back to land safely at JFK Airport. Delta ...
By taking advantage of wake updraft like migrating birds , Airbus believes an aircraft can save 5–10% of fuel by flying 1.5–2 nmi (2.8–3.7 km) behind the preceding one. After Airbus A380s tests showing 12% savings, it launched its 'fello'fly' project in November 2019 for test flights in 2020 with two A350s , before transatlantic flight ...
