Exploring the Plane

We're told that we live on a globe with a curve that drops 600ft from 30 miles away. Let's see if the evidence supports the claim.

This was one of my first observations way back in 2017 when visiting The Isle of Man. I could clearly see the entire lighthouse and below when according to the curve calculator the base should be blocked by the curvature. Earth is flat.
