I just watched the entire recording. It still gives me chills watching huge engineering projects like that succeed. All those young people! Looks like nobody is over 40! What a thrill for all of them. What a career!
Kinda fits, too — there were an awful lot of engineers in their 20s and 30s in the Apollo program as well. We humans tend to peak early. Althooooooough, there’s that old saying, “Old Age and Guile will always prevail over Youth and Skill.” 😊
