ABSTRACT:
Paired flying disks utilizing in-flight aerodynamic induced separation. A second disk is nested within a first disk so that such can be easily thrown together as one flying disk and provide repeatable vertical separation in flight. The outer or larger disk has vanes above corresponding openings and/or holes employed in body of the disk to divert air from the top side or other location to the underside thereof to assist the separation of the disks from one another in flight. After separation, both disks follow the same flight direction making it possible for a single person to consistently catch both of the disks.
