With an auto level I measured the visual drop of the surface of the Earth. If you just want the results fast forward to 10:20.

Instrument used: Leica NA 332

If you doubt the auto level is level, then the crane on the island can be used as a control "stick", flickr.com/photos/138443523@N08/42549428402
