So you actually believe the earth is flat? Interesting. I'm not gonna try and convince you otherwise. But if you look up weather balloon/ go-pro, you can see litterally hundreds of amatuer videos of people letting go of a weather balloon, with a go-pro and gps, travelling over 100,000 feet plus, and you can see the blue horizon and the curvature of the earth, done by ordinary people all around the world. If you're lucky enough you can find the one where the jet passes 10,000 feet underneath. Pretty cool. I grew up in the Rockies and now live in the prairies, never have I seen a river flow up hill.
