1. An aircraft comprising:
- opposed wings each comprising a first wing portion and a second wing portion, the second wing portion of each of the opposed wings moveably attached to the first wing portion, wherein when the second wing portion is moved to a flight configuration the second wing portion is parallel to the first wing portion and forms with the first wing portion a continuous wing, and when the second wing portion of each of the opposed wings is moved to a landing/takeoff/hover configuration the second wing portion is oriented non-parallel to the first wing portion breaking up the continuous wing;
two wing-mounted thrust-producing devices each attached to the respective second wing portion of the opposed wings and configured to move, upon movement of the second wing portion relative to the first wing portion, from the landing/takeoff/hover configuration in which the two wing-mounted thrust-producing devices provide thrust in a first direction to the flight configuration in which the two wing-mounted thrust-producing devices provide the thrust in a second direction; and
two fuselage-mounted thrust-producing devices attached to a fuselage of the aircraft, the fuselage-mounted thrust-producing devices positioned at opposite sides and evenly spaced from a centerline between the two wing-mounted thrust producing devices, wherein the aircraft is unmanned.

Abstract
An aircraft takes off, lands, or hovers with at least one wing-mounted thrust-producing device attached to at least one wing of the aircraft and at least two fuselage-mounted thrust-producing devices attached to a fuselage of the aircraft both providing vertical thrust. The aircraft is flown while the at least one wing-mounted thrust-producing device provides horizontal thrust and with the at least two fuselage-mounted thrust-producing devices not providing any thrust.

10. An aircraft comprising:
-
opposed wings of an aircraft, which is unmanned, each comprising a first wing portion and a second wing portion, the second wing portion of each of the opposed wings moveably attached to the first wing portion, wherein when the second wing portion of each of the opposed wings is moved to a flight configuration the second wing portion is parallel to the first wing portion and forms with the first wing portion a continuous wing, and when the second wing portion of each of the opposed wings is moved to a landing/takeoff/hover configuration the second wing portion is oriented non-parallel to the first wing portion breaking up the continuous wing; two wing-mounted thrust-producing devices attached to the respective second wing portion of the ends of the opposed wings of the aircraft; and two fuselage-mounted thrust-producing devices attached to a fuselage of the aircraft and positioned at opposite sides and evenly spaced from a centerline between the two wing-mounted thrust producing devices; wherein when the aircraft is in flight the two wing-mounted thrust-producing devices are configured to provide horizontal thrust and the two fuselage-mounted thrust-producing devices are configured to not provide any thrust, and when the aircraft is landing, taking off, or hovering each of the two wing-mounted thrust-producing devices and the two fuselage-mounted thrust-producing devices are configured to provide vertical thrust. - View Dependent Claims (12, 13, 14)

15. A method of flying an aircraft comprising:
-
taking off, landing, or hovering with the aircraft, which is unmanned, with two wing-mounted thrust-producing devices attached to respective second wing portions of opposed wings which are disposed non-parallel to respective first wing portions of the opposed wings of the aircraft, and two fuselage-mounted thrust-producing devices attached to a fuselage of the aircraft both providing vertical thrust; and moving the second wing portions to be disposed parallel to the respective first wing portions to form a continuous wing and flying the aircraft while the two wing-mounted thrust-producing devices provide horizontal thrust and the two fuselage-mounted thrust-producing devices do not provide any thrust. - View Dependent Claims (16, 17, 18, 19, 20)
