I remember it. I was at school and we were all taken into the canteen where there were several TVs around, to watch it. I am glad of that, because I do believe it was real, it happened.
Why? Because the most straight forward answers are usually the right ones, in my experience.
So I believe the moon landing took place, I believe Harold Holt drowned and was NOT whisked away in Japanese sub, Diana died because she was dumb enough to get into a car without doing up her seatbelt. There are no reptilian aliens, only us. And so on.
Makes life much simpler.
Besides, the American space program had its share of disasters and we shared those too.
I wish they would hurry up with the next phase, a Mars mission.
