About this route:
A direct, nonstop flight between Geelong Airport (GEX), Grovedale, Victoria, Australia and Lemhi County Airport (SMN), Salmon, Idaho, United States would travel a Great Circle distance of 8,532 miles (or 13,731 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 Geelong Airport and Lemhi County 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 Geelong Airport and Lemhi County Airport. You'll see that it will travel the same route of the red line on this map!

Facts about Geelong Airport (GEX):
- Because of Geelong Airport's relatively low elevation of 140 feet, planes can take off or land at Geelong 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 furthest airport from Geelong Airport (GEX) is Flores Airport (FLW), which is nearly antipodal to Geelong Airport (meaning Geelong Airport is almost on the exact opposite side of the Earth from Flores Airport), and is located 12,178 miles (19,599 kilometers) away in Flores Island, Azores, Portugal.
- The closest airport to Geelong Airport (GEX) is Avalon Airport (AVV), which is located only 16 miles (25 kilometers) NW of GEX.
Facts about Lemhi County Airport (SMN):
- The closest airport to Lemhi County Airport (SMN) is Challis Airport (CHL), which is located 45 miles (72 kilometers) SSW of SMN.
- 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.
- 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.
