The episode was re-shot sometime between 21 July and 30 July 1965 part way through the season. The village scenes were shot in Wighton, the shoreline scenes were shot at Holkham Gap, and the airfield scenes were shot at then disused RAF Sculthorpe (which had, for some time prior, been a USAF base), near Fakenham, in Norfolk.
