Funny, in one way your calculator agrees with me. It says at 51 miles, there'd be 32 ft of curvature. Which is pretty close to what I posted. The diagram doesn't make sense to me, how is it that h0 != h1? Does the earth curve more after distance d1? Of course not. Nor does the diagram make sense that at seven miles out (distance d1) the eye would meet the horizon at a height of 32 ft. It would be at 25.5 miles, not seven.
However, I realize I forgot that I have to square the distance, which makes the total curve value much greater. So that means at a minimum that you'd have to be on a hill or cliff about 7.98*51*51/12/2=865 feet high. High, but impossible.
But, I believe your link is more correct. The formula I'm using is an approximation and not very accurate for long distances.
Still, the US Military says they can see Russia from Alaska. So I believe that.

H0 is the hill on one side and h1 is the hill on the other side.
You have plenty of formulas on Horizon - Wikipedia[^]
With the interesting one here[^]

Well, yes, I realize now that the diagram is being general, but since we're talking curvature of the earth, then d1 should be diagrammed as d1 = d0/2 and h0 = h1. But that maybe is too specific to my tastes.
In any case, my point is that Russia and Alaska are visible to each other, if only slightly and in specific locations and under specific conditions.

well, not really.
You can only see about 5km at sea level because of the earth curvature (unless you are a flat-earther).
I'd rather be phishing!

You can if you're on a hill or cliff. See my response here[^]

Oregon is a beautiful place, infested with liberal idiots. That alone wouldn't be so bad - targets being expensive to buy these days - but unfortunately for decent citizens, they run things there.
There are many beautiful places here in the US; no need to emigrate to the Left Coast.

If you put Nutella on salmon, do you get salmonella?
Bad command or file name. Bad, bad command! Sit! Stay! Staaaay...

Definitely not. My last boss'es name was Antonella and we gave her all kinds of nicknames. Salmonella, Vampirella and even Alosaurus (spelling intentional), but anything as good as Nutella simply would not have fit.

I feeling so much better I might go see a movie, the manatee showing of course.

Nah, it's some film with lots of CGI, most of it generated in CoralDraw.
