Nonstop flight route between Shemya, Alaska, United States and Atwater, California, United States:

About this route:

A direct, nonstop flight between Eareckson Air Station (SYA), Shemya, Alaska, United States and Castle Airport (MER), Atwater, California, United States would travel a Great Circle distance of 3,236 miles (or 5,208 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 Castle 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 Castle Airport. You'll see that it will travel the same route of the red line on this map!

• Because of Eareckson Air Station's relatively low elevation of 97 feet, planes can take off or land at Eareckson Air Station at a lower air speed than at airports located at a higher elevation. This is because the air density is higher closer to sea level than it would otherwise be at higher elevations.
