This was not an Airwave glider, although Airwave did produce later versions of the Vision Mark 4 and Vision Pulse under the "Calypso" name. It was produced by Pacific Windcraft, of Salinas, California, from 1982 to 1985, when it was replaced by the Vision Eclipse. At one point, a few Vision sails were shipped to manufacturers in England and France, where they were fitted onto locally made airframes.
The Vision was the first double-surface glider to use a harder cloth for the main body and a softer cloth for the double surface, a configuration that allowed for higher camber at the loads experienced in landing. This resulted in a glider that was nearly as easy to land as a single-surface glider while providing a speed range more characteristic of a double-surface glider.
It was designed by Jean-Michel Bernasconi, with some help on the sail from me, as I was the head sailmaker for Pacific Windcraft.
