As for me, I was confused in that I thought I was entering a login ID and not a user ID that would be displayed. "moon1969" is just an easy phrase for me to remember that I sometimes use for login IDs (and have used as a password in the past but no more).
After the fact, I could make the connection that I live in Houston, and have lived close to Johnson Space Center, and have known people who worked directly or indirectly for NASA, and have witnessed the benefit of the federal dollars flowing in.
Also, I had a highly educated friend who was convinced that we did not really land on the moon in 1969, and it was a hoax. I thought it was a weird thought. I now know that is a conspiracy theory. Still think it is weird.
