-Wow, the Space Race is still neck-and-neck I see. I'm guessing the BIG Artemis mission will be coming up soon? That is, unless, Germany or somebody else reaches the Moon first...
-Nephilim sounds like TTL's equivalent of The Day After in terms of being anti-nuke fiction. Of course, a novel with philosophical cred is a ton more respectable than a manipulative "tear-jerker" starring Steve Gutenberg rolleyes so maybe it'll work better here. I do have to wonder if a stand-in for either Star Trek or Doctor Who exists, and if so whether a possible post-nuclear holocaust would be a recurring theme.
-The 1974 election results seem (by the end of that paragraph) tied to a desire for America's industrial base to not degenerate into OTL's Rust Belt, which is refreshingly forward-thinking for your standard voter base. Or am I reading too much into that part? Also, nice little architecture update on the Bicentennial Building.
There isn't an exact stand in for Star Trek ITTL. The closest thing is The Explorers (1964-1968) which has the basic premise of Star Trek: Voyager but strays a little closer to science fantasy and can be pretty cheesy at times. There is also Farside (1972-1974) which is akin to Star Trek: Deep Space 9 and Babaloyn 5 and deals with more political themed issues. Both franchises only earned modest viewer ratings but over the years will build massive fan followings. The TL doesn't have anything really close to Doctor Who.
