I don't see the point. It seems like a huge expense (you're not as successful at claiming that ten thousand dollars is chump change as you think you are) only to demonstrate something that's not really inconsistent with FET anyway. At best it shows that the Earth might actually be round, but it lacks the immediacy that observing the Earth from ground level affords.
When I say "affordable", I mean in contrast to performing the same experiment 30+ years ago.
Of course, the biggest problem with ground-level observation is that the round Earth theory cannot be observed from the ground level if the requirement for evidence is direct observation because the round earth theory states that the Earth is a specific size, and because of its size, the curvature cannot be casually observed. I'm sure one can imagine if a microbe was on a beach ball, that microbe would not see a curve in the beach ball either because it lacks the proper height to be able to notice the curve. But to further complicate ground-level observation as being able to confirm the round earth theory, we add to the mix, the varying heights in land and this exaggerates the phenomena. You have to get high enough to be able to see it at a distance to where its spherical curve can be seen plainly.
Personally, I don't care if the Earth is round or flat ... I accept the truth whatever it is. It bears no consequence on my life one way or the other. I've just seen and learned far more evidence that validates a round Earth theory whereas the Flat Earth theory hasn't seemed to stand up to a lot of tests. It doesn't seem to explain solar or lunar eclipses, nor does it have any way of predicting them (that I know of) whereas the spherical model of Earth with a heliocentric sun in the solar system has yielded mathematical models that can predict those events with second precision (in addition to the locations of the other planets using similar mathematical technique). I'm not aware of a flat earth model that is capable of making those predictions.
But I am open to learn.
Heck, I'm not aware of how the FET explains the rest of the planets ... We all know they are out there, but the question is, if the sun is hovering above a flat Earth in a circular motion, then what force is keeping the other planets in their "orbits"? and why are we able to see them? If our sun is as close to the Earth as is postulated, certainly its light could not be reflecting off of the other planets. Unless the theory says that the planets are much closer to us and much smaller than is commonly understood. But even if that is the idea, there should be some way of measuring their distance using understood mathematics, no?
