A disc-shaped aircraft including an airfoil having a convex upper surface and a planar lower surface with the edges of the surfaces meeting at the periphery of the disc and having a plurality of rotational mini turbine jets affixed sequentially at the edge of the circumference of the disc, the turbine jets effecting vertical, horizontal, and directional thrust under computer and pilot control. Stable flight is maintained by an internal gyroscopic counter-rotating rotor blade system, individual control of the turbine jets, and a series of retractable flaps.
