An aircraft useful as a toy or as a personal craft which includes a plurality of blades freely rotatably mounted on a spherical body supported by landing means. The blades are hinged onto arms to swing up and down for upward flight or downward landing. Funnel members are mounted at the end of the arms to act as counterweights and drag propellers. A rocket is mounted under the body for vertical take-off and will rotate the blades. When the rocket shuts off, the blades will swing up and down to feather the aircraft. A pair of rockets are mounted also on the body under the blades for horizontal thrust. The aircraft can take-off vertically or horizontally and lands without power like a parachute.
