National Paper Airplane Day

National Paper Airplane Day, observed on May 26th, celebrates the simple, enduring pastime of folding paper into gliders and flying them, an activity enjoyed by children and adults alike for generations. Paper folding for flight has roots stretching back centuries, with some historians tracing early paper aircraft concepts to ancient China, where paper was invented, and to Leonardo da Vinci, who reportedly experimented with paper models to test some of his early aerodynamic and flight concepts during the Renaissance. The modern classic paper airplane design, and the schoolroom pastime of folding and flying them, became particularly widespread in the 20th century, closely tracking alongside the broader rise of aviation itself as airplanes captured public imagination throughout the century. Despite their simplicity, paper airplanes actually demonstrate genuine aerodynamic principles, including lift, drag, thrust, and weight, the same fundamental forces that govern full-scale aircraft flight, making paper airplane folding and flying a popular, accessible tool for introducing basic physics and engineering concepts in educational settings. Competitive paper airplane throwing has also developed into an organized pursuit, with dedicated distance and duration record competitions, including entries recognized by Guinness World Records, drawing serious enthusiasts who experiment extensively with different folding techniques, paper weights, and throwing methods to maximize flight performance. On this day, people of all ages are encouraged to fold a paper airplane and see how far or how long they can make it fly.
