Flying for free (25c3)

Birds, glider pilots, and recently UAVs can exploit a variety of weather effects in order to gain altitude, remain airborne and travel long distances all with no power input – effectively, hacking the atmosphere to fly for free. This talk will explain the aircraft, techniques, meteorology, hardware and software that we use to achieve this. In the process I will show why the sport of gliding may be of interest to hackers, and explain how you too can get involved in this highly rewarding and low-cost form of flying. about this event: http://events.ccc.de/congress/2008/Fahrplan/events/2940.en.html
