December 24, 1968
The first humans orbit the moon. Apollo 8 astronauts Borman, Lovell and Anders.
I was 15 and the suspense for me was, the far/dark side of the moon. No human had ever seen the far side of the moon with there own eyes. If I remember correctly the ground crew would lose radio contact for a few minutes while the Apollo crew was on the far side of the moon which elevated concerns.
Happy Holidays to All!
