Nonstop flight route between Eau Claire, Wisconsin, United States and Sofia, Bulgaria:

About this route:

A direct, nonstop flight between Chippewa Valley Regional Airport (EAU), Eau Claire, Wisconsin, United States and Sofia Airport Vrazhdebna (SOF), Sofia, Bulgaria would travel a Great Circle distance of 5,181 miles (or 8,338 kilometers).

A Great Circle is the shortest distance between 2 points on a sphere. Because most world maps are flat (but the Earth is round), the route of the shortest distance between 2 points on the Earth will often appear curved when viewed on a flat map, especially for long distances. If you were to simply draw a straight line on a flat map and measure a very long distance, it would likely be much further than if you were to lay a string between those two points on a globe. Because of the large distance between Chippewa Valley Regional Airport and Sofia Airport Vrazhdebna, the route shown on this map most likely appears curved because of this reason.

Try it at home! Get a globe and tightly lay a string between Chippewa Valley Regional Airport and Sofia Airport Vrazhdebna. You'll see that it will travel the same route of the red line on this map!
