Abstract : The patent relates to a retrieval assembly, in combination with an airborne vehicle capable of hovering (e.g., a helicopter), for use in retrieving a downed drone airborne vehicle. The assembly includes a hook subassembly, a pole subassembly which includes a multi-purpose pole, a recovery cable subassembly, and a swivel subassembly, all of which cooperate to capture, lift, support, and carry the downed drone vehicle. The drone, thereby, can be safely suspended beneath the helicopter, and also can rotate while dangling without twisting and subsequently breaking the recovery cable from which the drone is dangling. Therefore, the drone can be reliably, safely, quickly, and easily retrieved.
