A manned or unmanned aircraft has an upper body and a lower body. The aircraft has a circular shape and a circular outer periphery. One or more rotor blades extend substantially horizontally outward from the main body at or about the circular outer periphery. In addition, one or more retractable control flaps are coupled to the lower body and are moved between a retracted position recessed from the outer periphery and an extended position outward of the outer periphery to engage lift blade thrust.
