Space fantasy fan-boys and fan-girls have just received their latest damage-control propaganda update from actor Richard Branson where he claims to have gone to space and filmed the spinning-ball Earth for us (but really he just did some parabolic maneuvers simulating free-fall while in a fancy plane)!
Unfortunately for old Dick and his riders, rather than use a normal lens to film the Earth, like all honest amateurs do when sending up their high altitude balloons, these space virgins, just like NASA, Space X, the Red Bull dive and all other so-called "official" sources, always suspiciously choose to use a fish-eye lens causing the horizon to constantly and radically warp from convex, to flat, to concave.
As the camera tilts relative to the horizon the ends warp up or down respectively, but when held still and level the horizon is flat.
As the normal back camera shows, the horizon actually remains perfectly flat and rises to the eye-level of the camera all the way up.
