How are Seeds of maple trees dispersed?

Maples have a fruit called a samara, which means that the fruit is a wing. You've probably seen maple samaras, or maybe samaras from other trees. They look like little "helicopters" falling down. Maples actually have double samaras, so there are two samaras attached. They each have their own seed which is enclosed in the papery wing. Samaras are adapted to dispersal by wind.
