Except this was by ordinary people. Go strap a camera to a weather balloon and take pictures yourself. No fisheye lens required.
No, you know what, you don't even need to do that, just sit by a harbor and watch distant ships approach. The top of the ship will be visible while the rest still appears to be beneath the sea (because of the curvature of the Earth). I've witnessed it myself and so can you.
Don't make me laugh, you can see the curvature from the wide angle lens when the balloon is 20' off the ground.

Ships going over the horizon as proof of a globe ROFL. I'm sorry but you've gone full retard, go learn about how perspective works.
