Abstract: An aerodynamic device for being launched for flight through the air and having three inherent parameters of rotation while moving through the air, the first being a yawing vector imparted by the launcher as the device rotates about its own center of symmetry, the second being a roll vector as it rotates about an axis parallel to its direction of flight, and the third being rotation of the device very slowly about a center which is determined by the launching point whereby a boomerang action is provided.
