Nonstop flight route between Changi, Singapore and Marion, Illinois, United States:

About this route:

A direct, nonstop flight between Singapore Changi Airport (SIN), Changi, Singapore and Williamson County Regional Airport (MWA), Marion, Illinois, United States would travel a Great Circle distance of 9,610 miles (or 15,465 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 Singapore Changi Airport and Williamson County Regional 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 Singapore Changi Airport and Williamson County Regional Airport. You'll see that it will travel the same route of the red line on this map!

Facts about Singapore Changi Airport (SIN):

• Concerned that the existing airport was located in an area with potential for urban growth, which would physically hem it in on all sides, the government subsequently decided in 1975 to build a new airport at the eastern tip of the main island at Changi, at the existing site of Changi Air Base, where the new airport would be easily expandable through land reclamation.
