Float a world of free flight

Float is an documentary about the world of indoor rubber powered model airplanes. After watching it and doing some reading online, I’ve learned that the people who compete in free flight duration aeronautics are a special breed. Imagine spending 40 years of your life building self-propelled airplanes that weigh as much as a paperclip but maintain altitude for over 30 minutes. Oh, and you’d like to compete with others who do the same thing? Just catch the next flight to Serbia.
