| BBC Induction Course. Colonel Chilvers was the resident BBC expert on nuclear defence and he gave us an induction course lecture on the effects of atomic warfare, He told us enthusiastically about the "foul dust" that would rain down for a mile or two around "ground zero" which was going to be Charing Cross station. He was fairly certain of that. (also conveniently, the hub of Late Night Transport although we didn't know about that yet) The greatest danger was, we were told, the ensuing firestorm. Dresden and Cologne may have been mentioned but his demonstration involved a dummy birthday cake adorned with about twenty Prices' standard candles (each, no doubt radiating one lumen, but we didn't know about those either, yet.) These were lit and allowed to burn for a while. Convincingly the smoke and flame from each candle was deflected inwards towards an increasingly concentrated burning area above the centre of the cake. The cool air drawn in from the sides fed the flames until the candles went into overdrive and started melting and collapsing inwards. Brilliant. I can't recall how it was put out or, come to think of it, anything else on that two week induction course except my first BBC meal. At 1.15pm on the 2nd of October 1962 in the Broadcasting House canteen, I had Spam Fritters. They were absolutely awful and I can tell you that I never in the following 42 years had spam fritters ever again anywhere. It may have been a BBC psychological ploy though, because however awful any future canteen meal might be I could always somehow manage to eat it, telling myself : "At least this isn't as bad as spam fritters." Peter Fox TO14 ................................. (We used, in those days of cold war, to discuss what we would actually do in the event of the four minute warning of incoming nuclear missiles, given that we were a prime target. Apart from the obvious, standing on the top of the East Tower at Television Centre seemed to be favourite.) |
