Admittedly, GoPro does actually have a lens distortion going on so that it can be wide angled. It actually makes it look more globe like than it is, as you can see from numerous sky diving videos. In them you can see this distortion by noting that the skyline is straight when it goes through the center of the view but looks highly curved when on the side.
Yeah, but then if you yourself were situated high enough to see the curvature of the earth, it's just because of whatever drugs they distribute via the contrails, and not actually real.
