I was 14 going on 15 so was in Form 4 ...
I was 16, still in the UK and working for my father as an apprentice plasterer at the time. I remember that we knocked off work early that day so we could get home early to watch the whole shebang on TV... along with a few dozen neighbours because we had the only TV in the village at that time.
So yeah, the moon landing brought people together, some that may not have been otherwise, and it changed the lives of billions on the planet. We have a multitude of products at our disposal thanks to the space programme and the scientists/engineers who worked so hard to pull it off.
Nope, the"giant step for mankind" was NO hoax.
