Hang gliding has its origins in the designs of Leonardo da Vinci in the 15th century. It emerged as a modern activity in the 1960s when the Southern California Hang Gliding Association was formed in 1971. Hang gliders now use advanced designs and instrumentation. Pilots can engage in different types of flying like thermaling or cross country flying. Beginners can start with an introductory tandem flight before taking a two-day introductory course to learn basic techniques like launching and landing. Hang gliding involves risks but can be made safer through lessons from certified instructors and use of proper equipment.
