First impressions come when they come. I read G. C. Edmondson's 1965 The Ship that Sailed the Time Stream and its sequel, 1981's To Sail the Century Seas at a very young age (too young, apparently, to pick up the casual racism and sexism), long before my callow transformation into a young Reaganite, of which the less said the better. All the more wonder that I still and so vividly record the protagonist realising that he had returned to 1970s San Diego waters when he picked up one of the local radio commentators. The vividness of the memory probably has something to do with the author's palpable disgust for paleo-conservatism. Whatever: It is a first impresson.San Diego=appalling, hateful, racist, anti-communist conservatism. Got it!
Nuance is surely badly wanted, but this technological appendix isn't about politics --well, it's not going to escape labour politics, but that's another matter. It is about the San Diego-built Consolidated/Convair PB4Y-2 Privateer. such as, for example, "Turbulent Turtle." BuNo 59645 belonged to the "secret Special Electronic Search Project," but was attached to VP26, then stationed at Port Lyautey, Morocco, was sub-detached to Wiesbaden for a ferret flight along the Baltic coast of the Soviet Union, during which it was shot down by a La-11 of the PVO on 8 April 1950.
