That is covered in this video.
Here's the transcript. Where does it say you can see NY skyscrapers from 300 miles out in the Atlantic Ocean with a telescope - even one 20-50ft above the water line?

Dennis Dero said, “The great tragedy of science is the slaying of a beautiful hypothesis by an ugly fact.” If the Earth is a sphere or a ball, then there must be evidence of a curved surface.
0:15
Generations of children and adults from Aristotle to Roman times to this day have believed that the curve can be proved by watching ships gradually disappear as they move away, going over the curved surface of a spherical Earth. Because it is going around the curve of the Earth, right? But does this really prove the Earth is a ball?
0:36
Mathematicians have worked out a mathematical formula based on spherical trigonometry to calculate what happens when a ship goes over the horizon and disappears from sight. The formula for finding how far a distant object is below the horizon is 8 and 2/3 of a foot per mile.
0:55
C = 2/3 × D˛. The answer is in feet, where C is the curve and D is the distance. For example, a ship at sea is 10 miles away. How far is the ship below the horizon? C = 2/3 × 10˛. The answer is 66.6 feet.
1:33
The above formula is based on basic spherical trigonometry. But if one goes to check this formula on the internet, one will see how a simple idea can be expressed so complexly that even scientists find it hard to follow. According to critics, the change is recent to support a spherical Earth and heliocentricity.

This experiment will need two experimenters and two or more monitors. Apparatus needed is a video camera with a large zoom lens, access to a large lake, preferably frozen on a very calm and clear day.
2:04
Set up a station on the edge of the lake and place a marker on the ice 3 miles away. Use a drone flying at a constant controlled 1 meter above the ice so as to pass over the 3-mile marker. The drone camera will identify the marker and stop, hovering in place still at 1 meter above the ice.
2:27
Can the experimenters see the drone with the naked eye, or has it gone over the curve? Or has it disappeared because the drone has gone beyond the vanishing point, the limit of the human eye to see in the distance?
2:40
Now video the drone using the zoom lens and ask: can it still be seen? Now repeat the experiment but put the marker at 6 miles away and video through the zoom lens. Carefully collate the video footage. Repeat the experiment for analysis.
2:57
There are other factors that need to be taken into consideration. Of course, in this experiment there is no need to use complex contrived mathematical equations — just simple observation and common sense.
3:06
Is water flat? The Earth is over 70% water, and water is flat. So where is the curve?
3:17
Whenever experiments have been tried on the surface of standing water, the surface has always been found to be level. If the Earth were a globe, the surface of all standing water would be convex. This is experimental proof the Earth is not a globe.
3:34
No curve is seen when mountains are observed at a distance as well. Edward Henry cites John McIntyre, who researched three mountains: Mount Tenant, Mount Greybeard, and Mount Frypan, all very nearly the same height.
3:48
Standing on Mount Tenant, McIntyre expected to see Mount Greybeard lower than Mount Frypan because of the curve of the Earth, since it was 34 miles away. But to his shock and surprise, it was the same height.
4:03
When scientists are confronted with these factual results, they will split hairs to bend the results to support what they believe. But belief always carries the day, not science.
4:16
According to critics, when scientists discovered the Earth was a flat plane, they realized they had a problem. So how did they cope with the spherical Earth theory that was so well developed and inscribed into the human psyche for centuries?
4:29
They had gone too far down the rabbit hole to turn back. The truth about the real shape of the Earth is too shocking. So they wrapped the flat Earth map around a globe.
4:41
But this made problems of their own, such as those found on Mercator’s projection, where Greenland appears much larger than it really is. In actual fact, Greenland fits 13 times into the continent of Africa.
4:56
The strategic map in the White House is there for military uses should the USA be attacked. The famous Blue Marble is not a photograph of the Earth from space, as many believe. It is a composite of strips of a flat Earth map.
5:12
Any flat image can be wrapped around almost any 3D shape. These are just some of the many Blue Marbles made over the years.
5:26
But this is not a photograph. It is admittedly photoshopped strips wrapped around a sphere. Also, the image of the Milky Way galaxy cannot be a photograph, since no vehicle carrying a camera has ever been outside the galaxy.
5:45
It is an artist’s impression of a theoretical idea. But how many people believe this is an actual photo?
5:52
Mountain ranges reflected in lakes are a good example of the flat Earth. If Earth is a sphere, then lakes should behave as convex mirrors and the reflection should be smaller.
6:04
But what do we actually see? These photos show perfect reflections that are exactly the same size as the mountains, indicating the water is flat.
6:34
You may conduct your own experiment using a regular flat mirror and a convex car mirror. You will see the image in a flat mirror is the same size, while the image in a convex mirror is smaller.
6:53
Many films show the Earth from high altitude as a sphere, especially the Felix Baumgartner jump in 2012. But the cameras used are fisheye lenses that distort straight lines.
7:26
When filmed with a regular lens, the horizon appears flat. Critics claim there is deliberate deception by space agencies to exaggerate curvature.
8:09
When Baumgartner stepped out, the external camera showed a curved horizon. Critics say this was done deliberately. The curve appears too sharp to represent the whole Earth.
8:59
The horizon is neither convex nor concave — it is flat.
9:10
The first view from space was from a V2 rocket in 1946. A regular lens shows a flat Earth. NASA later used fisheye lenses to exaggerate curvature.
9:47
Balloonists in the 19th century reported that the horizon rose to eye level as they ascended.
10:31
If the Earth were flat, why can we not see cities 50 miles away? Because of perspective and the limitations of the human eye.
10:55
Perspective explains why distant objects appear smaller and eventually disappear at the vanishing point.
11:37
Zoom lenses can bring objects back into view. Ships that appear to disappear can be brought back into view using zoom.
12:23
Ships do not vanish over the curve of the Earth. The idea taught in schools is not credible proof of curvature.
12:47
Water always finds its level. If Earth were a sphere, water would have to curve, which contradicts physical reality.
13:41
Rivers such as the Nile flow thousands of miles. If Earth were a sphere, they would have to flow uphill at some point.
14:29
Gravity is said to be weak, yet it supposedly holds trillions of tons of water on a spinning Earth moving at enormous speed.
14:54
A simple experiment using a level and a plank on a beach shows the horizon is flat.
15:35
Canals and railways are built level for hundreds of miles with no allowance for curvature.
16:44
Surveyors and engineers have never needed to account for curvature in practical work.
17:42
If Earth were a sphere, pilots would have to constantly dip their noses downward to follow the curve.
18:26
Navigation uses plane trigonometry, not spherical trigonometry, proving Earth is flat.
19:43
Since 2014, many people have conducted experiments showing Earth is flat.
20:05
NASA avoids addressing these arguments and instead ridicules flat Earth proponents.
21:09
Like ships disappearing over the horizon, flat Earth arguments are dismissed rather than addressed.
