About this route:
A direct, nonstop flight between St. Louis Downtown Airport (CPS), Cahokia, Illinois (near St. Louis), United States and Kharkhorin Airport (KHR), Kharkhorin, Mongolia would travel a Great Circle distance of 6,454 miles (or 10,386 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 Kharkhorin 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 Kharkhorin Airport. You'll see that it will travel the same route of the red line on this map!

Facts about St. Louis Downtown Airport (CPS):
- The furthest airport from St. Louis Downtown Airport (CPS) is Margaret River Airport (MGV), which is located 10,998 miles (17,700 kilometers) away in Margaret River, Western Australia, Australia.
- 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.
- The airport closed in 1959 and reopened six years later as Bi-State Parks Airport.
- St. Louis Downtown Airport (CPS) has 3 runways.
- 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.
Facts about Kharkhorin Airport (KHR):
- Kharkhorin Airport (KHR) currently has only 1 runway.
- The furthest airport from Kharkhorin Airport (KHR) is Cochrane Airfield (LGR), which is nearly antipodal to Kharkhorin Airport (meaning Kharkhorin Airport is almost on the exact opposite side of the Earth from Cochrane Airfield), and is located 12,222 miles (19,669 kilometers) away in Cochrane, Chile.
- The closest airport to Kharkhorin Airport (KHR) is Khujirt Airport (HJT), which is located 24 miles (39 kilometers) S of KHR.
- Because of Kharkhorin Airport's high elevation of 4,759 feet, planes must typically fly at a faster airspeed in order to takeoff or land at KHR. Combined with a high temperature, this could make KHR a "Hot & High" airport, where the air density is lower than it would otherwise be at sea level.
