Re: Tremendous place, this museum
The story about Coventry has been, I think, comprehensively debunked. There is no evidence that the target of the raid was known before the afternoon of that day when the German navigation beams were switched on and converged over Coventry. There were messages warning of an imminent raid but three targets were given, no definite date was specified and the cities were given codenames. The codename for Coventry was not worked out until after the event.
Sounds trite but, as the saying goes, "you can't make an omelette without breaking eggs." In order to win the Battle of the Atlantic, the information that the U-boat codes had been broken had to be protected. At all costs. And, yes, that meant some convoys were not completely protected. War is a nasty business.
But, it is indisputable that the knowledge of Colossus which emerged in the late 70's and continues to emerge today, completely rewrote the history of the birth of electronic computing.
That aside, thankyou so much for this article. BP is a world-class site aned deserves all the attention it can get. Anyone with a remote interest in computing and history will be completely enthralled by the place.
