Nonstop flight route between San Diego / El Cajon, California, United States and Shannon (County Clare), Ireland:

About this route:

A direct, nonstop flight between Gillespie Field (SEE), San Diego / El Cajon, California, United States and Shannon Airport (SNN), Shannon (County Clare), Ireland would travel a Great Circle distance of 5,122 miles (or 8,243 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 Gillespie Field and Shannon 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 Gillespie Field and Shannon Airport. You'll see that it will travel the same route of the red line on this map!
