An aircraft operable to transition between thrust-borne lift in a VTOL orientation and wing-borne lift in a biplane orientation. The aircraft has an airframe including first and second wings with first and second pylons coupled therebetween. A distributed thrust array is coupled to the airframe including a plurality of propulsion assemblies coupled to the first wing and a plurality of propulsion assemblies coupled to the second wing. A cargo pod is coupled between the first and second pylons. The cargo pod is rotatable between a loading configuration, substantially perpendicular to the wings and a transportation and deployment configuration, substantially parallel to the wings. A flight control system is configured to independently control each of the propulsion assemblies and to autonomously deploy a payload from the cargo pod at a desired location.

An unmanned aerial vehicle (UAV) includes a central body and a plurality of landing gears that are extendable from and movable relative to the central body. The plurality of landing gears are configured to transform between a flight configuration and a surface configuration. In the flight configuration, the landing gears are extending laterally away from the central body and not in contact with a surface below the central body. In the surface configuration, the landing gears are extending towards the surface below the central body. When the landing gears are in the surface configuration, the landing gears are configured to support a weight of the central body on the surface and transport the UAV over the surface by moving one or more of the landing gears relative to the surface.
