You are the one pretending here.
Pretending, what?
So many things.
You are pretending that Earth being round will magically make it disappear from view through a level tube, regardless of FOV, even though a level tube can easily allow you to see the ground a few 10s of m in front of you, where the curvature is insignificant.
You are pretending that by elevating yourself off Earth, it will magically change the drop over 1 mile from 8 inches to 5 feet. Even though it is the exact same drop.
You are pretending that objects can only be hidden by tilting over.
You are pretending that the amount of the turbine hidden is massive, when in fact it is ~ 0.001% of Earth. A tiny amount.
You are pretending that the tilt required would be massive, when math and a too scale diagram shows you that is pure BS.
You are pretending that the evidence presented to you is fake.
And with all that, you are pretending your irrational hatred and irrational attack on the RE is backed up by reason and evidence, and pretending that the RE which you cannot refute has none.
Lots of pretending there.
My mindset against a globe gets stronger and stronger by the minute.
Only because you don't care about the truth and wilful reject reality.
If that belief of yours was actually justified you would have no problem answering the trivial questions which you continue to flee from, or admitting that some of your claims about the RE are in fact incorrect.
Again, care to answer the trivial questions which clearly show you are wrong (And no, that doesn't mean to change the question to what you want it to be so you can pretend you aren't wrong):
How far below the tube can an object at 1 mile distance be, in order to still be visible through the tube?
Can you see the base of a tree at 1 mile distance, if the base of the tree is 6 ft below the level of the tube?
Again, what magic prevents us from seeing the RE through a level tube?
Again, what should the tilt be (provide a number with units and math justifying it) for an object 30 km away?
How much of such an object should be hidden at a 30 km distance, if you are standing 2 m above the RE?
What is the level of uncertainty in your measurements of allegedly flat water in your sink, in terms of both angle and change in height?
What is in the region indicated in red? Ground or sky?
