Theoretically, they are correct. If you drive 1000 miles west, there is no curve. The Earth is flat for us. You have to get really high up to see the curvature and nobody has time for that.
The invention of the telescope and its use at sea gave sailors the chance to see receding land and vessels gradually “sink” from view at they moved away. So they knew. And speaking of Pythagoras, even the ancient Greeks knew the Earth was a sphere. So it’s not as if the idea was created in the same mythical underground lab where they staged the moon landings.
“If you drive 1000 miles west, there is no curve.”
I once calculated the curve of the earth for 100 miles. I can’t remember how much it was, but a tower would have to be extremely tall to be visible.

Actually, no. It is very easy to see earths curvature if trees and other things aren’t in the way. The next time you take a ship ride from a city notice that as you go out to sea that you can see the tops of buildings much longer than you can see the shoreline, that is an example of the visible curvature of the earth.
Sure they do.

Be sure to get one that isn't using a fish eye lens.
Sunrise high altitude balloon to the edge of space over Texas
And it came down and was recovered locally 2.5 hours later.
Think about that for a bit.
if you drive 38,000 miles west.. you end up where you started... so theoretically...they are incorrect...lol
1000 miles, no curve? Sooooo...You can see back to the beginning of those 1000 miles?
