Nonstop flight route between Cahokia, Illinois (near St. Louis), United States and Pretoria, South Africa:

About this route:

A direct, nonstop flight between St. Louis Downtown Airport (CPS), Cahokia, Illinois (near St. Louis), United States and Wonderboom Airport (PRY), Pretoria, South Africa would travel a Great Circle distance of 8,790 miles (or 14,146 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 St. Louis Downtown Airport and Wonderboom 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 St. Louis Downtown Airport and Wonderboom Airport. You'll see that it will travel the same route of the red line on this map!

• The closest airport to St. Louis Downtown Airport (CPS) is Lambert–St. Louis International Airport (STL), which is located only 16 miles (27 kilometers) NW of CPS.

• Because of St. Louis Downtown Airport's relatively low elevation of 413 feet, planes can take off or land at St. Louis Downtown Airport 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.
