Of course not ... in your example they have difersnt perspectives of the object . The person at 6 would see the boat disappear as it moved away, the person at 3 would never see the boat at all.

I was referring to a ship leaving from 4:30 towards 10:30 , they would see the same thing at the point the ship goes over the curve or possibly nothing at all, depending of course on the size of the vessel and their distance from each other(size of the circle)

That quote explains your life perfectly, nice post

Globe Earth FTW!

They use transponders (unless you're suiciding like MH370) to identify which planes are which radar returns.

Now, how about we go back so you can finish addressing conspiracy math?

Your model has no sun, moon, etc. and it's day everywhere. Doesn't seem to work that well. Try again

Radar

noun: radar
A system for detecting the presence, direction, distance, and speed of aircraft, ships, and other objects, by sending out pulses of radio waves which are reflected off the object back to the source.



damn curvature, why u gotta ruin everything?

Dude, I've forgotten more about radar than you know about it. Your entirely ignorant comment is noted and duly dismissed. Radar works just fine.

fixed it for you bro

That's why radars are installed at the highest possible point on a ship; to get the maximum possible range. They won't work past the curvature and that's the reason why there are also over-the-horizon radars that "bounce" the signal on the ionosphere to extend the range greatly.

If the Earth was flat, boat radars would be able to detect pretty much each and every ship in the entire ocean, and that's not the case. Guess that Earth isn't flat after all.
