Nonstop flight route between Sioux City, Iowa, United States and Cape Romanzof, Alaska, United States:

About this route:

A direct, nonstop flight between Sioux Gateway Airport (SUX), Sioux City, Iowa, United States and Cape Romanzof Air Force Station Cape Romanzof Long Range Radar Site    (CZF), Cape Romanzof, Alaska, United States would travel a Great Circle distance of 3,059 miles (or 4,923 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 Sioux Gateway Airport and Cape Romanzof Air Force Station Cape Romanzof Long Range Radar Site   , 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 Sioux Gateway Airport and Cape Romanzof Air Force Station Cape Romanzof Long Range Radar Site   . You'll see that it will travel the same route of the red line on this map!
