2. The horizon is always at eye level
“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 large. Because of its size, the horizon only dips by an amount too small to notice with the naked eye even at very high altitudes. For a typical aircraft height of 35,000 feet The horizon would only have dipped 3.3 degrees. Even at a height of 20 miles the horizon would only have dipped by 5.8 degrees.
The video below shows the horizon dropping as an aeroplane climbs in altitude by comparing the horizon relative to the wing tip.
The following video by the same author who is a pilot shows the head up display in his aircraft showing that the horizon is below the aircraft's horizontal plane ... ie below eye level.
The following video again by the same author takes a more direct approach and simply uses a surveyors level to show that the horizon is below eye level.
