So, watching the video, the sun being a circle 20 miles up means it's OBVIOUSLY a disc, right? Or is ALL THE LIGHT being "bent" up to 20 miles, in which case the earth isn't lit at all.
Oh wait, same picture, and it is.
Weird.
2:47 seconds in the video, and you can see the sun shining, full circle, on the camera. just before and after that, you can ALSO see that part of the earth is lit.
