1999: Going Commercial
The Jump: Slovenian jumper Robert Peknik and Jari Kuosma of Finland test a prototype of their BirdMan suit, what would become the first commercially-available wingsuit. "I came down and was absolutely high," Kuosma said of their first successful jump in the suit.
Why It Matters: "Those guys spawned the movement. By designing the first wingsuits people could actually get their hands on, they basically created the sport," says Corliss.
