High Quality Content by WIKIPEDIA articles! Red Bull Flugtag (German: flight day, airshow) is an event owned and operated by Red Bull in which competitors attempt to fly homemade size (max 10m / 30 ft) and weight (max 150 kg / 330 lbs) limited human-powered flying machines. The flying machines are usually launched off a pier about 30 feet (9.1 m) high into the sea (or suitably sized reservoir of water). Most competitors enter for the entertainment value, and the flying machines rarely fly at all.
