About this route:
A direct, nonstop flight between Margaret Ekpo International Airport (CBQ), Calabar, Nigeria and Lemhi County Airport (SMN), Salmon, Idaho, United States would travel a Great Circle distance of 7,480 miles (or 12,038 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 Margaret Ekpo 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 Margaret Ekpo 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 Margaret Ekpo International Airport (CBQ):

- Because of Margaret Ekpo International Airport's relatively low elevation of 210 feet, planes can take off or land at Margaret Ekpo 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.
- Margaret Ekpo International Airport (CBQ) currently has only 1 runway.
- The closest airport to Margaret Ekpo International Airport (CBQ) is Akwa Ibom International Airport (QUO), which is located only 18 miles (30 kilometers) WSW of CBQ.
