About this route:
A direct, nonstop flight between Shonai Airport (SYO), Yamagata, Japan and Lemhi County Airport (SMN), Salmon, Idaho, United States would travel a Great Circle distance of 5,055 miles (or 8,136 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 Shonai 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 Shonai Airport and Lemhi County Airport. You'll see that it will travel the same route of the red line on this map!

Facts about Shonai Airport (SYO):
- The airport opened in 1991 after lobbying efforts by local chambers of commerce, as the area was highly isolated from the major cities of Tokyo and Osaka, requiring half a day of travel to reach either.
- In addition to being known as "Shonai Airport", other names for SYO include "庄内空港" and "Shonai Kūkō".
- Shonai Airport (SYO) currently has only 1 runway.
- Because of Shonai Airport's relatively low elevation of 72 feet, planes can take off or land at Shonai 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 Shonai Airport (SYO) is Yamagata Airport (GAJ), which is located 42 miles (67 kilometers) SE of SYO.
- In December 2012, an ANA flight landing from Tokyo overran the runway at Shonai.

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.
- 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.
- 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.
