Nonstop flight route between Shemya, Alaska, United States and Port Huron, Michigan, United States:

About this route:

A direct, nonstop flight between Eareckson Air Station (SYA), Shemya, Alaska, United States and St. Clair County International Airport (PHN), Port Huron, Michigan, United States would travel a Great Circle distance of 4,418 miles (or 7,111 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 Eareckson Air Station and St. Clair County International Airport, 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 Eareckson Air Station and St. Clair County International Airport. You'll see that it will travel the same route of the red line on this map!
