About this route:
A direct, nonstop flight between Lemhi County Airport (SMN), Salmon, Idaho, United States and Hamilton Airport (HLT), Hamilton, Victoria, Australia would travel a Great Circle distance of 8,612 miles (or 13,860 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 Lemhi County Airport and Hamilton 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 Lemhi County Airport and Hamilton Airport. You'll see that it will travel the same route of the red line on this map!

- Because of Lemhi County Airport's high elevation of 4,043 feet, planes must typically fly at a faster airspeed in order to takeoff or land at SMN. Combined with a high temperature, this could make SMN a "Hot & High" airport, where the air density is lower than it would otherwise be at sea level.
- Lemhi County Airport (SMN) currently has only 1 runway.
- The furthest airport from Lemhi County Airport (SMN) is Tôlanaro Airport (FTU), which is located 10,686 miles (17,197 kilometers) away in Tôlanaro, Madagascar.
