I had a friend in college in the mid-1970s. He was in engineering, and his dream was to get hired by one of the major shipyards near the beginning of development of a new aircraft carrier, because he knew design to delivery would take up the majority of his career.
I was in my late 20s when one of the trust managers at the bank I worked for brought in his Osborne. I was so very, very jealous. I'd just purchased the CP/M cartridge for my Commodore 64 and tried to convince him let me borrow the WordStar disk, but he wouldn't do it (and I really never went anywhere with CP/M on the C=64).
I recently toured SEA. The third (western-most) runway there is too close to homes to use regularly for takeoffs due to noise. Though the FAA has made the Port of Seattle no promises, they apparently do tend to use the third runway as much as possible for landings only, and not late at night as much as possible.
I'd argue that the setting doesn't make "A Fire On The Deep" anything close to a fantasy. The Tines are a non-human species at a certain stage of development that's similar to humanity's medieval period. There's no more fantasy there than Michael Crichton's "Timeline."
