Nobody who has been on the moon is a Flat Earther. Smaller diameter of the moon is instantly obvious since you can see the curvature from ground level. Have to be at very high altitude to see that on our planet.
Here's one from onboard the rover. I remember the live TV feed from back in the day, and it was just this ghostly black & white. You couldn't hardly see anything. These film cameras are great.
The rover footage of the ascent module lifting off is really good as well. I have some old VHS of several of the landings, including Shepard playing golf and the rover being filmed from afar. They beat the crap out of at least one rover.
