Nonstop flight route between Knoxville, Tennessee, United States and Hydaburg, Alaska, United States:

About this route:

A direct, nonstop flight between McGhee Tyson Airport (TYS), Knoxville, Tennessee, United States and Hydaburg Seaplane Base (HYG), Hydaburg, Alaska, United States would travel a Great Circle distance of 2,644 miles (or 4,255 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 McGhee Tyson Airport and Hydaburg Seaplane Base, 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 McGhee Tyson Airport and Hydaburg Seaplane Base. You'll see that it will travel the same route of the red line on this map!
