About this route:
A direct, nonstop flight between St. Mary's Airport (KSM), St. Mary's, Alaska, United States and Bulgan Airport (UGA), Bulgan, Mongolia would travel a Great Circle distance of 3,428 miles (or 5,516 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. Mary's Airport and Bulgan 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. Mary's Airport and Bulgan Airport. You'll see that it will travel the same route of the red line on this map!

- The furthest airport from St. Mary's Airport (KSM) is Cape Town International Airport (CPT), which is located 10,494 miles (16,889 kilometers) away in Cape Town, South Africa.
- Because of St. Mary's Airport's relatively low elevation of 312 feet, planes can take off or land at St. Mary's 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 closest airport to Bulgan Airport (UGA) is Kharkhorin Airport (KHR), which is located 115 miles (185 kilometers) SSW of UGA.
- Because of Bulgan Airport's high elevation of 4,236 feet, planes must typically fly at a faster airspeed in order to takeoff or land at UGA. Combined with a high temperature, this could make UGA a "Hot & High" airport, where the air density is lower than it would otherwise be at sea level.
