I never watched Cronkite during the space race. I used to devour TV coverage from Gemini through Apollo, but I always like to watch ABC with Frank Reynolds and science editor Jules Bergman.
I was watching some coverage of the first moon landing and walk a few days ago on the occasion of the anniversary. It was Cronkite's coverage, and I was struck by how he seemed like such a geezer. After Armstrong's first words. Cronkite was babbling "what'd he say? A giant step for mankind? Did anybody get that?!" All the while Armstrong is still describing his first impressions while Cronkite is talking over him. Guess he was just excited...
