About this route:
A direct, nonstop flight between Exeter International Airport (EXT), Exeter, United Kingdom and Lemhi County Airport (SMN), Salmon, Idaho, United States would travel a Great Circle distance of 4,622 miles (or 7,438 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 Exeter International 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 Exeter International Airport and Lemhi County Airport. You'll see that it will travel the same route of the red line on this map!

Facts about Exeter International Airport (EXT):

- Scheduled services to the Channel Islands began in 1952 and charter flights to various locations followed.
- Because of Exeter International Airport's relatively low elevation of 102 feet, planes can take off or land at Exeter 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.
- Exeter International Airport (EXT) currently has only 1 runway.
- The furthest airport from Exeter International Airport (EXT) is Dunedin International Airport (DUD), which is located 11,994 miles (19,302 kilometers) away in Dunedin, Otago, New Zealand.
