It's a good video, but sadly, it's 50 years ago and Flat-Earthers are out of touch with today's reality --- Mars Curiosity--- so there's no WAY they're going to believe the moon landings.
No matter how good the video is, they'll watch it think that they are smarter than the video. No matter how much over their head it is, they're the smarter ones for not getting duped.
It's the only way to feel good about yourself.
It's a sad, flat world.
