Nonstop flight route between Christiansted, Saint Croix, United States Virgin Islands and Ulan Bator, Mongolia:

About this route:

A direct, nonstop flight between Henry E. Rohlsen International Airport (STX), Christiansted, Saint Croix, United States Virgin Islands and Chinggis Khaan International Airport (ULN), Ulan Bator, Mongolia would travel a Great Circle distance of 7,878 miles (or 12,678 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 Henry E. Rohlsen International Airport and Chinggis Khaan International 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 Henry E. Rohlsen International Airport and Chinggis Khaan International Airport. You'll see that it will travel the same route of the red line on this map!

Rohlsen International 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.
