Just a thought experiment, let's say the earth is flat, looks like many professionals would know, including
Pilots/ATC/sea captain
Land surveyor and civil engineers
Astronomers and Geologists, at least the one dealing with experimental data
Militaries, at least radar operator and artillery
Just these categories are already a lot of persons, I assume I miss a lot of others. So how many person does it make in total ? 10 % of the population ?
It wasn’t the main guy but one of the guys on site doing the pole experiment. I recall him saying “that’s interesting” after confirming the test worked, proving the curvature. It sounded like he was questioning his beliefs, but during the credits he’s on a podcast or radio show making some bs up about how the test was wrong.
