This is just an idea....
No claims made for a theory or hypothesis.
Or even if it would be practical or possible.
I rather doubt that there is a highway that would be straight enough and level enough.
.
Here is the idea. But....If you could.
Let's assume you are at Mile Marker 1 and then take sights on Mile Markers 2 and 3 with a telescope
Could you perform an experiment something like the Bedford Level ?
On second thought , I apologize for this idea.
I was thinking of some stretches of I-40 across the Mojave Desert.
But I rather doubt that you would be able to find any road that would be perfectly flat and perfectly level for several miles for this experiment.
Any road is going to have at least a few ups and downs and a few curves, no matter how small. Even I-40.
Not such a good idea.
Not very practical.
But I am going to try to see if I can see at least from one mile marker to the next on my next trip with a telescope or binoculars.
I have read that there is one highway in Australia where this might be possible.
Moderator, you may delete this subject if you wish.
This may be a little off topic and maybe something more suited to one of the Titanic-related forums.If the Carpathia's lookout has line-of-sight to the lifeboats, then they have line-of-sight to him. Along the same line. Even if you can see farther than the pure horizon due to refraction, the photons refract along the same path in each direction.
Would the lookout in the crow's nest on Carpathia see the Titanic's lifeboats first or would those in the Titanic's lifeboats see the top of Carpathia's highest mast first ?
I believe there were reports that the rockets from the Carpathia were seen well before the Carpathia appeared over the horizon.
Again.......Due to the curvature of the earth.

You could still do it and just include the elevation change in the calculations. Geodetic surveyors not only determine elevation, but take it into account while doing their jobs and calculations.This may be a little off topic and maybe something more suited to one of the Titanic-related forums.If the Carpathia's lookout has line-of-sight to the lifeboats, then they have line-of-sight to him.

Thanks, Rounder.
That was my deduction. Since the crow's nest on the Carpathia was a considerable height above the sea, those in the lifeboats would see it at the same time the lookout saw them.
That does raise the questiion. Woiuld those in the lifeboats see the tip of the mast before the lookout saw them ?
But if the earth was flat they would see not only the mast, but the whole ship- hull to mast - just appearing larger as it aproached them.
Just the old "ship over the horizon."
Also about the same as those warnings on those "eighteen wheelers" ....." If you can't see my mirrors, I can"t see you."
I hereby abandon my "experiment" for lack of a perfectly flat, perfectly level elevation , perfectly straight roadway.....For at least 3 miiles.
If someone else wants to pick up on it, they have my blessings . LOL

Also, ask earth levelers. They are about as far from NASA propagandists as you can get. But they will tell you that you can only use a laser for about 1/4 of a mile. After that it is not accurate enough. This is because the laser is shooting in a straight line which is level with the position of the laser. As you move further away from the laser, it gradually begins to shoot "uphill" in relation to the earth at that location. Up until 1/4 mile the effect is small enough to ignore. After that they need to make an adjustment - otherwise, according to how water behaves, they will be going uphill and not level.
