wig
Wig craft in simple terms are flown just above the water. this allows the craft to depend on what is known as ground effect, this is the phenomena that allows pelicans to fly so effeciently just above the waters surface. the air is compressed between the surface, ground or water and the wing. this creates a little additional lift which allows a wig craft fly along just a few feet of the surface of the water. if the wig goes to high it looses the ground effect and will glide back down till it finds the lift again. kinda neat huh!
