200 Proofs that Eric Dubay is a liar and an idiot

"Some people claim to have seen the curvature of the Earth out their airplane windows. The glass used in all commercial airplanes, however, is curved to remain flush with the fuselage. This creates a slight effect mixed with confirmation bias people mistake for being the alleged curvature of the Earth. In actuality, the fact that you can see the horizon at eye-level at 35,000 feet out both port/starboard windows proves the Earth is flat. If the Earth were a ball, no matter how big, the horizon would stay exactly where it was and you would have to look DOWN further and further to see the horizon at all. Looking straight out the window at 35,000 feet you should see nothing but "outer-space" from the port and starboard windows, as the Earth/horizon are supposed to be BELOW you. If they are visible at eye level outside both side windows, it’s because the Earth is flat!" One relevant point, and some more lies Earth curvature seen from airplanes is due to image disto...

“The horizon always rises to the eye level of the observer as altitude is gained, so you never have to look down to see it. If Earth were in fact a globe, no matter how large, as you ascended the horizon would stay fixed and the observer / camera would have to tilt looking down further and further to see it.” An unsubstantiated claim that is simply untrue This is a rather bizarre claim because even assuming a flat Earth simple trigonometry tells us that the horizon would drop as we gained altitude.  However, it would drop less.  It would be nice if Flat Earthers were precise with their claims, but for this proof I will just assume that Dubay is being imprecise and sloppy as usual and really means that on a flat Earth the horizon would not drop noticeably, and on a spherical earth the drop would be very noticeable, and that when we rise in altitude ... say on an aeroplane, we do not notice the horizon dropping. Flat Earthers can’t seem to understand that the Earth is very...
