All selected teams flown their planes from a 25 meter long and 6 meters high constructed runway using only human power. Each team, consists of one pilot and 3 assistants, so that he could lead the aircraft while the assistants help to hover as far as possible before landing in the water.
While the sky may be the limit on creativity, there are still a few flight regulations. First off, all flying machines must be entirely human-powered (no external energy sources or stored power). Second, no matter what they say, size does matter – all crafts must be less than 8 meters wide and must weigh no more than 180 KGs including the pilot. Safety is paramount; therefore all competitors must wear a life jacket and helmet.
Since the first Red Bull Flugtag took place in Vienna, Austria, in 1991, more than 100 Flugtags have been held around the globe, attracting up to 300,000 spectators for a single event.
