The wings were first used in the 1930 in order to increase horizontal displacement. These primitive aerial costumes were made of materials such as canvas, wood, silk, metal and whale bones. These suits were not very reliable, 72 of its 75 gliders were killed in the tests. In the 1990, the French paratrooper Patrick de Gayardon developed a new aerial suit that had incomparable safety and efficiency. Unfortunately, De Gayardon died on 13 April, 1998 in Hawaii while testing a new modification to his suit. In 1999, Jari Kuosma from Finland and Robert Pečnik from Croatia came together to create a new suit that was safe and accessible to all pilots, so they created BirdMan Inc. BirdMan's Classic, designed by Robert Pecnik, was the first airsuit to be offered to the general public. BirdMan was also the first company to promote the safe use of aerial suits by offering a program for instructors. This program, created by Kuosma, was made to try to convince that aerial suits were not dangerous and also to offer the new pilots a way to safely enjoy what was once considered dangerous even in the world of skydiving. With the help of instructors Scott Campos, Chuck Blue and Kim Griffin, a new teaching program was created to prepare new instructors. Phoenix-Fly, Fly Your Body, and EG Wingsuits have also developed their own training programs based on their own products.
