They must be “in” on the conspiracy. So is NASA, of course, all the world’s governments, every rocket scientist, all the airline/shipping companies that use global maps to navigate, all the satellite companies, every company that uses satellites, everyone that has seen a satellite (which is not hard to do), every sailor throughout history who has seen distant ships disappear below the horizon, and our own eyes whenever we see a sunrise or sunset. So why is half the world lying to the other half? That’s the biggest secret of all!
“everyone that has seen a satellite”
These flat earthers probably think satellites just bounce back and forth like the Pong arcade game.
