An aircraft capable of (a) sustained powered rotary-wing-mode VTOL flight and (b) sustained powered non-rotary forward airplane-mode flight, the aircraft comprising: a hub; a pair of wings (110, 112) coupled to the hub and serving as both rotary wings in rotary-wing-mode VTOL flight and as a pair of lifting wings in airplane-mode flight; a fuselage coupled to the hub; and a propulsion component configured to provide propulsion for the aircraft sufficient for sustained powered flight, wherein the propulsion component includes a plurality of thrusters (120, 122, 130, 132) including at least one thruster on each wing of said pair of wings (110, 112), wherein said plurality of thrusters provide sustained rotation of the pair of wings (110, 112) in said rotary-wing-mode VTOL flight and sustained forward motion of the pair of wings (110, 112) and of the entire aircraft in said non-rotary forward airplane-mode flight, wherein said at least one thruster on a first one of said pair of wings (110, 112) is able to thrust in substantially an opposite direction from propulsion from said at least one thruster on a second one of said pair of wings (110, 112) in said rotary-wing-mode VTOL flight and, wherein said propulsion from said at least one thruster on said first one of said pair of wings (110, 112) is able to thrust in substantially a same direction as propulsion from said at least one thruster on said second one of said pair of wings (110, 112) in said non-rotary forward airplane-mode characterized in that the fuselage is located under the pair of wings (110, 112) when the aircraft is in said rotary-wing VTOL flight and in said non-rotary forward airplane -mode flight. a hub; a pair of wings (110, 112) coupled to the hub and serving as both rotary wings in rotary-wing-mode VTOL flight and as a pair of lifting wings in airplane-mode flight; a fuselage coupled to the hub; and a propulsion component configured to provide propulsion for the aircraft sufficient for sustained powered flight, wherein the propulsion component includes a plurality of thrusters (120, 122, 130, 132) including at least one thruster on each wing of said pair of wings (110, 112), wherein said plurality of thrusters provide sustained rotation of the pair of wings (110, 112) in said rotary-wing-mode VTOL flight and sustained forward motion of the pair of wings (110, 112) and of the entire aircraft in said non-rotary forward airplane-mode flight, wherein said at least one thruster on a first one of said pair of wings (110, 112) is able to thrust in substantially an opposite direction from propulsion from said at least one thruster on a second one of said pair of wings (110, 112) in said rotary-wing-mode VTOL flight and, wherein said propulsion from said at least one thruster on said first one of said pair of wings (110, 112) is able to thrust in substantially a same direction as propulsion from said at least one thruster on said second one of said pair of wings (110, 112) in said non-rotary forward airplane-mode characterized in that the fuselage is located under the pair of wings (110, 112) when the aircraft is in said rotary-wing VTOL flight and in said non-rotary forward airplane -mode flight.
