Many flat-earth diagrams use a north-pole azimuthal equidistant map. That projection preserves distance from the center, but it badly distorts distances between non-central locations — especially across the southern hemisphere. This tool compares globe great-circle distance with the same two points drawn on that flat map.
AE map assumption: North Pole center, Antarctica as outer rim. This is the common flat-earth poster map, not a complete physical model.
The line is straight on the flat map. On the globe, the shortest route is a great circle; those are not generally the same thing.

| “The AE map shows the real flat Earth.” | Then it must preserve real distances, routes, southern skies, seasons, and circumnavigation — not just look familiar. |
| “Antarctica is the outer wall.” | Southern hemisphere routes should become enormous if the map is literal. They do not. |
| “Flights are fake or impossible.” | Real flight times, fuel planning, shipping, and emergency diversions are operational checks on distance. |
