FLOAT is a documentary currently being filmed that explores the fascinating world of indoor rubber powered model airplanes. A hobby that is pursued by people from all walks of life and many countries around the world has never been captured before in such remarkable detail. This little known hobby involves the design, construction, and flying of ultra lightweight airplanes powered only by a wound rubber band. The planes are free-flight, meaning that they do not use any manual controls to fly, relying only on the skill of the builder and the design in order to stay aloft. This hobby is responsible for many if not all of the current technologies used in modern civil aviation, as the first powered flying device was in fact the Planophore model airplane by Alphonse Pénaud built 1871 and powered by rubber.
