I had the pleasure of being at the seaside two days ago, in the evening as the light faded. A fishing boat was going out from the harbour into the distance. When watching it from the beach, I could see the light on its mast perfectly clearly. However, when I crouched down, the light disappeared.
As the boat went further from me, so the amount I needed to crouch for it to vanish became less and less. The sea was calm, I estimate the highest waves to have been no more than half a metre at maximum. This is insufficient to obscure the light by getting in the way.
This first-hand observed phenomenon directly demonstrates the curvature of the earth, as one would expect if a sgement of a sphere was between myself and the boat. This nullifies the "it looks flat" claim from the brainless FE mantra squad, because if it looked flat one would always be able to see the light, no matter how low you crouched. It also disgrees with Rowbotham's Bedford Level Experiment.
FE'ers, please contribute to this thread by agreeing that this is what would be expected to be seen on a large sphere. You may not cite Rowbotham's perspective theory as it directly contradicts his Bedford Level Experiment results, and if you believe one thing Rowbotham says then you have to believe the whole book. You may not cite bendy light as that has been disproved by absence of predicted stellar distortions.
This observation was carried out entirely zetetically.
