The shape of the disc is an airfoil in cross-section which allows it to fly by reducing the drag and increasing lift as it moves through the air, compared to a flat plate.
Spinning the disc imparts a stabilizing gyroscopic force, allowing it to be both aimed with accuracy and thrown for distance.
Those for disc golf are usually smaller but denser compared to ultimate frisbee, and tailored for particular flight profiles to increase or decrease stability and distance.
They soon discovered a market for a light-duty flying disc when they were offered 25 cents (equivalent to $5 in 2023) for a cake pan that they were tossing back and forth on a beach near Los Angeles.
[6] After the war, Morrison sketched a design for an aerodynamically improved flying disc that he called the Whirlo-Way,[5] after the famous racehorse.
He and business partner Warren Franscioni began producing the first plastic discs by 1948, after design modifications and experimentation with several prototypes.
Headrick redesigned the Pluto Platter by reworking the mold, mainly to remove the names of the planets, but fortuitously increasing the rim thickness and mass in the process, creating a more controllable disc that could be thrown with higher accuracy.
Roddick began establishing North American Series (NAS) tournament standards for various Frisbee sports, such as Freestyle, Guts, Double Disc Court, and overall events.
[21] In addition, many championships have sprung up around the world and the sport has become very popular, with nine-time champion Miguel Larrañaga from Spain being the leading exponent of frisbee throwing.
Ultimate discs are made of durable plastic (often polyethylene) and are designed to be thrown for maximum distance and accuracy.
[35] This is a precision and accuracy sport where individual players throw a flying disc at a target pole hole.
[36] In 1976, the game of disc golf was standardized with targets called "pole holes" invented and developed by Wham-O's Ed Headrick.
Teams of two or three players are judged as they perform a routine that consists of a series of creative throwing and catching techniques set to music.
[39] The game of guts was invented by the Healy Brothers in the 1950s and developed at the International Frisbee Tournament (IFT) in Eagle Harbor, Michigan.
[40] A patented game scoring points by throwing and deflecting the flying disc and hitting or entering the goal.
In the 1970s, it developed as an organized sport with the creation of the Ultimate Players Association by Dan Roddick, Tom Kennedy and Irv Kalb.
