I remember you saying that the curve of windows in airplanes might mistake people into seeing curve. Did you ever figure this out? Can people see curve at 35k feet or how high according to science?

Well never really. I did point out that almost all plane windows are made by the same company. There can’t be a curve left to right or else if you followed that curve with your eyes where would it start or end. So the way our eyes work, even a Flat horizon like at the beach has to taper in at the ends. Think of it this way... we are the center of a circle of view so our view is always a radius. Meaning you can see equal distance in all directions which makes it a circle whether we are on a plane or a ball.
