One thing that interested me about the end of the movie was that Damien Chazelle chose not to show a photo of the real Neil Armstrong. I remember Chazelle saying that he does not approve of this in biopics, even though so many directors do so. #HATM

Neil did indeed take this stroll to Little West crater late in the Apollo 11 EVA. What we see here is accurate in that respect, though he passed away in 2012 without stating that he took anything belonging to Karen with him to the lunar surface. Jim Hansen still thinks he could have done so. #HATM

It has always been amazing to me that Neil and Buzz had just two and a half hours to work with outside on the lunar surface. The crews of the last three missions had three days to spend outside, each making an EVA about seven hours in length for each day. #HATM

Will any future astronaut have to manually redirect a lunar landing vehicle like we see here, to this dramatic an extent? Automation in flight has advanced amazingly over the last half century and will continue to advance. #HATM

Another of my favorite memories is watching Gene Kranz speak about this whole sequence at the Wings Over the Rockies Air and Space Museum, for the 50th anniversary in 2019. He is not in this movie, but it was amazing to hear the emotion in his voice, as if Apollo 11 had just happened. #HATM

When I was at Texas A&M working on my dissertation that became a book, I spoke with Dick Koos. He is the Simulator Supervisor who famously supervised the 1202 computer alarm that actually happened later that month aboard Eagle. He worked at NASA from 1960 to 1998 and lives in Iowa now. #HATM

It's always great to reflect on Apollo, but nowadays it's hard to watch this movie without reflecting on the Artemis program. The Apollo Lunar Module seen here was about 18 feet tall, while the SpaceX Starship that Artemis crews will take to the lunar surface is 160 feet tall! #HATM

For all of you who have watched both movies, what is your favorite Saturn V launch scene: Apollo 13 or First Man? I go back and forth between the two. In both cases, the musical choices almost take my breath away. The scenes remind me why I fell in love with Apollo. #HATM

How fortunate I was that Jim Hansen (seen in this scene) signed my copy of First Man himself. I arrived in 2009, two years after my friend Scott MacKenzie. #HATM

This speech from William Safire was made public for the first time in 1999, for the thirtieth anniversary of Apollo 11. I was going into seventh grade at the time and it blew my mind when I read it. #HATM
