‌The balloon – the origin of which is unknown – floated over the field off Bingham Road at around 6.30pm that evening. ‌It became entangled in the power lines above it, which caused sparks, and the sparks, falling, started a fire on the dry ground below. "Foil balloons are coated with a metal layer that can conduct electricity and should be kept well away from overhead power lines and other electrical equipment. If a balloon becomes caught in overhead lines, people should never attempt to retrieve it and should call us on 105." Whether they land in a field, a hedge or a power line – somebody else is dealing with them.
