Flat Earth Theory / Re: Walking in a straight line

When you walk along the north border you find it is 370 miles long following the 41st parallel. The southern border is 390 miles long.  If you follow the surveyed border it should keep you within the 10 parts per million as mentioned above.

Taking the surveyed border as a straight line wouldn't be the right thing on a globe, which is kind of the point of this entire line of inquiry.

If I had some means of generating a completely straight guideline that everybody - flat Earth theorists and globe theorists alike - could agree did generate lines that really are objectively straight, then all that would be required to settle the matter would be to set up a straight line that grazes both the peak of some mountain and the peak of another that projects above the horizon when viewed from the first, then send teams to follow the line in both directions.

If the Earth is flat, then either one of those teams would find a place where the line runs into the ground, or both would end up at the edge of the Earth.

If the Earth is a globe, then both of those teams would end up attempting to fly into space.

I would be interested in critiques of this thought experiment - especially on the definitiveness of its predicted outcomes - from a flat Earth theorist's point of view.

Lasers are not going to be convincing enough. I've seen round-earth defenders say they're subject to atmospheric refraction effects near the surface, and flat-earth defenders say that perspective messes them up. Looking for a straight-line reference that everybody will agree makes a straight line that I could in principle walk and/or fly along and doesn't ever deviate from perfect straightness by less than ten parts per million under any conditions. Not really interested in talking about sun angles and whatnot until that's sorted out, so I'll leave those points to others.

Flat Earth Theory / Walking in a straight line

Could somebody more familiar with Flat Earth theory than I am please explain to me what tools I would need to use in order to prove beyond all doubt that a line I'm following, by walking or driving or flying an aeroplane or sailing a boat along it, is truly and completely straight and does not deviate up or down or left or right from that straightness even by a little bit? Would prefer simple tools that NASA could not hack, if any exist.

If I'm finally going to get clear on what shape the world is, this seems to me to be where I'd need to start.

Thanks in advance.
