It was 210 nm off the coast and within the range of Chivenor however the USAF did it because they could get there quicker. I believe however, that it took them 2.5 hours on scene to effect the rescue and the casualty made it to hospital only 2 hours quicker than if they had sent Chivenor. I'm not sure just how much deck winching the USAF guys get to practise so they did well to get him off OK.
