About this route:
A direct, nonstop flight between Grand Central Airport (GCJ), Johannesburg, South Africa and Florida Keys Marathon Airport (MTH), Marathon, Florida, United States would travel a Great Circle distance of 8,074 miles (or 12,993 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 Grand Central Airport and Florida Keys Marathon 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 Grand Central Airport and Florida Keys Marathon Airport. You'll see that it will travel the same route of the red line on this map!

- Grand Central Airport (GCJ) currently has only 1 runway.
- Because of Grand Central Airport's high elevation of 5,327 feet, planes must typically fly at a faster airspeed in order to takeoff or land at GCJ. Combined with a high temperature, this could make GCJ a "Hot & High" airport, where the air density is lower than it would otherwise be at sea level.
- The closest airport to Grand Central Airport (GCJ) is O. R. Tambo International Airport (JNB), which is located only 12 miles (20 kilometers) SSE of GCJ.
- The furthest airport from Grand Central Airport (GCJ) is Hana Airport (HNM), which is located 11,992 miles (19,299 kilometers) away in Hana, Hawaii, United States.

This is because the air density is higher closer to sea level than it would otherwise be at higher elevations.
