Also, if the sun was a spot light, it would be obvious from the amount it moves in relation to the Virgin Galactic plane/spaceship, same with the moon. Also, even if the sun did cause a slight appearance of curvature it would be no where near enough to hide the earth being flat. Not to mention the fact that you would be able to see the ice wall. On a related note, I presume the orbital images of the south pole are 'faked' as well.
