"Here's some math on how to work out the required observation height to observe a given distance on a spherical surface or the distance to the horizon from a given observation height.
First, let's define a right triangle. r^2 + d^2 = (h + r)^2 where r is the radius of the Earth and d is the distance in a straight line from ground level extending tangentially to the surface of the earth (or what a flat-tard may call level from that perspective). h is the height above the ground that connects to the d line, the height that we're observing from in this case. Visually, this is what it looks like:
Let's say we have our observation height (h) and of course the radius of the earth (r), and we want to find d, the distance to the horizon. When we re-arrange the equation, we come up with this:
d = sqrt((radius of the earth in meters + 10000 meters)^2 - (radius of the earth in meters)^2) where the radius of the earth is (averaged out to) 6.371009×10^6 meters. That places the horizon at 357,100 meters at an observation height of 10,000 meters.
357,100 meters or 221.89 miles
Earth isn't a perfect sphere. So, accuracy will vary.
A lot of flat earth niggers like to claim that globe earth people think that the horizon drops by 8 inches per mile squared, math that I would expect from niggers if they could do anything resembling math. The observation deck would be have to be 881,260.88 inches or 22,384 meters high in order to be just at the horizon. It's 10,000 meters in reality.
For a visual representation, the nigger math would create a retarded parabola. Spheres don't look like this retarded parabola when viewed from the side.

I called a friend in Europe from North America at sunset on my end. The sun was going down on the horizon on my end and the sun was going up on his end. How could that be on a flat earth model?
jews have heavily pushed the globe in an obvious way since the 40s and op claimed flat earth to be a jewish psyop. I don't subscribe to one or the other, but figure there is more evidence of jews pushing the globe than flat earth.
hahahaha! You've made the world turn backwards, Moravian. Britain is about five hours LATER than the East Coast in the US. When it's 4pm in Florida, it's 9pm in Britain. So you and your delirious friend are just seeing things. You falsely claim that you called your friend at sunset your time and that it was sunrise in Britain. And, and we're supposed to support your opinion which is so obviously false. Sunset here is midnight in Britain and anybody can google it.

Lol, you absolute imbecilic reject. I was on the west coast and he was in central Europe at the end of summer. They are 9 hours ahead and the earth is a globe so when the sun was going down where I was (day almost over maybe 8pm or so) their next day was already starting (+ 9hrs) at 5am or so. So the only delusional retard here is you, lol.
It occurred to me when I was driving across the state that when it's storming, raining and lightning, that you can't see just how far the blue skys are away. I think it's like a metaphor or something.
There are no edges, apparently. Just an infinite ice region surrounding us. It's not even stupider than the infinite vacuum we are supposedly actually surrounded by.
UM AHCKSHOOUALIEY you can't because water vapor in the air makes it so you can only see so far.
Yes, that really is their cope. If you respond by asking why visibility doesn't change in response to humidity, that just means you believe NASA'S LIEEEEEEES!
Sure, but according to flat tard logic, any amount of water vapor in the air is the reason you can only see a certain distance on a clear day.
For example, there's a tourist trap in Key West that claims if you squint reeeally hard, you can see Cuba. You can't, because of the curvature of the earth. The flat tard will say it's because muh water vapor. Whether there's water vapor in the air or not.
According to flat earth logic perspective is the reason you can't see far. Pretty much the same reason we can't see the edge of the universe. It's too far away. You can see farther with a bigger telescope, but telescopes only go that far. And celestial bodies have the advantage of being very large.
Try using a telescope to see the flag that was supposedly put on the moon. You can't, because the moon landing was faked.

Edit, to add to this, the Greek mathematician Eratosthenes calculated the Earth's circumference in 250 BC. The experiment is simple to repeat. https://www.britannica.com/biography/Eratosthenes
