Back in the 60s CFS (H) had regular tasks winching cadets in the Peak District. We went up as a pair, from memory, GK flying and our USAF exchange Major Ed in the other. Just after arrival a high speed 'front' came through. We were just ahead of it and escaped down the valley. Major Ed got caught in it and put down close to a house, in a heavy snow storm. He was about to get out and noticed they had been surrounded by sheep - he reckoned they were not friendly natives and decided to stay on board until the storm passed!
