Tips

Drag to rotate, scroll to zoom. The great-circle arc (yellow) is the shortest path between two points on a sphere. On a flat Mercator map it looks curved — but it's Mercator that lies, not the globe.

Hint: A straight line on a Mercator map is not the shortest path. A flight from Oslo to Tokyo goes over Siberia — not across Europe.
