Abstract: An unmanned airborne vehicle (UAV) recovery system for in-flight recovery of a fixed wing UAV includes a catching device and a plurality of hover-capable drones, such as multi-rotors. The catching device is for catching the fixed wing UAV via a hook system during flight of the fixed wing UAV and takes the form of a line between the recovery drones. The recovery drones are arranged to support the catching device as it spans a gap in a horizontal orientation with the catching device suspended between at least two recovery drones that are in flight and spaced apart horizontally from each other either side of the gap. During a recovery operation the recovery drones co-ordinate their movement to adopt a flight path relative to a flight path of the fixed wing UAV to define a virtual runway for interception of the fixed wing UAV by the recovery system.
