So you guys are ok with taking the word of one man on his experiments, but you can't trust the distances we've been given for the landmasses of the continents of the Earth and the oceans? Because that's what I'm getting out of this. The numbers for the distances across the states are easy to find. The distances for the width of Australia, Europe, NA, SA, Asia, Africa and Antarctica are easy to find, as well as the distances broken down into smaller chunks. You're telling me that we can't trust any of those distances? That you blanket refuse to use them in an effort to put together a map because...why exactly? If making a map is so hard, how did the map of the globe come about? How is it accurate at the local level for everyone? Where did the distances for the Rand McNally Road Atlas come from? Your claim boils down to "We can't make a map because all the people who created maps and charted distances that are available online are part of the Round Earth conspiracy!!!!1!1!!"
Once again your post contribution in that thread seems to be "Disprove me because that's what you have to do!" rather than understanding it's on you to provide the proof. If you can't make a map that works with known distances (hopefully/potentially corroborated via flight times) you don't have a theory. You have a hypothesis, and a rather poor one at that.
The issue is that no one in the society will give serious consideration to the notion of simply "looking up" distances. Questions will arise on whether it was calculated on the presumption of a globe, and flight logs will be necessary. Then there is a matter that planes do not make direct straight line paths to their destinations, will regularly use jet streams, be delayed, etc.
It is also not a given that taking a flight from location A to location B tells us the distance between those two points based on the time of arrival. One might theorize that an aircraft has a cruising speed of so and so miles per hour, but how was that calculated? Based on assumed Round Earth distances when the plane made a test flight to a "known" location in its development?
As you can see, the matter is all a little more complicated than just needing to Google distances.
