After reading the article I decided to check out the authors blog, Vintage Space. I particularly enjoyed this piece written about Apollo 8, or more accurately, the events that led up to the Apollo 8 mission.
Reading this made me wonder what John McCain had to do with with Apollo 8 (You'll have to read the article to find out why). This lead to some genealogical confusion for a bit, but this article from PBS and good ol' Wikipedia helped clear things up for me.
I enjoyed this particular journey through history, I highly recommend reading these articles. Especially the PBS one.
