The "failure is not an option" quote was never said by Gene in real life, it came from the Tom Hanks Apollo 13 movie. Who's to say that this quote wasn't therefor in relation to any number of the Apollo missions up to 22.They still referenced the movie's fictional line 'failure is not an option' though when they put up the memorial picture of Gene. Which leads me to assume they still had some issue re: Apollo 13.
Worried they will skip Challenger as well once they get to the 80s.
Also a ton of skipping happening during the last few episodes. Whatever happened to the injured kid? did she finally pull the plug? again, edited 'for time'
I get the impression that you'd prefer a show that is closer to reality than For All Mankind is. In the show universe, the money and resources available to Nasa is much higher than in reality due to the continuation of the "space race". The Challenger disaster probably never happens in this universe, but perhaps other incidents will. The explosion of Apollo 23 that killed Gene of course never happened, nor did the challenges with the Apollo 24 mission, which is perhaps as close to real-life 13 as we'll get this series. The Sea Dragon never got beyond the design stage in reality and the SS missions never left earth orbit. We are going to see a drastic change to the timeline next season with a whole new set of failures and successes.
