Not so much of a breakdown, per se, but once, in the 1990s, a BBC news bulletin finished on BBC1, and we went to the weather. But, instead of the presenter in vision, going through the various moving images, we could only hear Bill Giles, talking over a map they usually would use at closedown, when the duty CA
done the weather out of vision. This map had the descriptions in summary over the appropriate areas.
When the forecast started, Bill Giles explained all. There had been a power cut where the weather came from, and the lights had only just came back on a few minutes before he was due on air. So, we had the unusual situation of Bill Giles doing the weather out of vision.
