So my line of reasoning is along the lines of, from a fixed point a on the ground and a fixed point b somewhere else on the ground, travelling from point a to point b along the ground should be shorter than travelling from an altitude plumb to point a to the same altitude plumb to point b, while maintaining the altitude during travel, IF the earth is a globe.

If the earth is flat then the distances should be exactly the same.

I'm sure a diagram would help but I'm reluctant to get mspaint out and hopefully my explanation is good enough to illustrate what I'm getting at.

If my reasoning is correct then I'm imagining a drone could do this. It could fly directly up from a point, altitude should be able to be maintained from air pressure. Not entirely sure how a drone can determine distance travelled though without gps help or something else that could be used against the test. The idea is that drone travels x distance but comes down way before point b which is x distance away from point a.

If my reasoning is correct then I'd imagine it all falls apart in the numbers. How far apart would point a and point b need to show a significant result? How high would it have to be to show a significant result? (I do appreciate there should be a relationship such that the higher you do it the less distance you need). How accurate would instruments need to be to maintain altitude? I'm really not good enough with numbers to be able to work any of that out myself.

If my reasoning is incorrect (most likely) then no doubt Mick'll come along to poopoo my idea in seconds But jokes aside I do learn from having my mistakes pointed out to me. Honest!
