Don't worry, It's just flying over the curvature

For those that think ships disappearing into the horizon means that they are sailing over the curvature of the Earth.

All you have to do to disprove this silly belief is go to the beach with your camera, and use it to zoom in on the ships you think have passed over the curved water. Somehow you see the ship come back into view when doing this! Is it magic? NO, it just means that there's no curved ocean water anywhere on Earth.
