Understood, and have taken into account.
The video clip you show is the introduction of the Mercury 7, almost 10 years before we landed on the moon, went to space. These men seem more excited than the men who actually landed on the moon. If you watch all 3 parts of the interview you posted, you will see a smirk that rarely left John Glenn's face that would make the Cheshire cat envious. The rest of the Mercury 7 still show a lot more enthusiasm that the first people to walk on the moon.
Personally, and just my observation, I think it's very, very odd.
Second event would be either the Vietnam war, I think this is where mass media discovered it's power to mold public perception. Next would be 9/11.
Btw: the smirk is known as "Dupers Delight". Anyone not familiar with this term, should be!
