About this route:
A direct, nonstop flight between St. Mary's Airport (KSM), St. Mary's, Alaska, United States and Asmara International Airport (ASM), Asmara, Eritrea would travel a Great Circle distance of 6,957 miles (or 11,196 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 St. Mary's Airport and Asmara International 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 St. Mary's Airport and Asmara International Airport. You'll see that it will travel the same route of the red line on this map!

Facts about St. Mary's Airport (KSM):
- The closest airport to St. Mary's Airport (KSM) is Mountain Village Airport (MOU), which is located only 13 miles (20 kilometers) W of KSM.
- Because of St. Mary's Airport's relatively low elevation of 312 feet, planes can take off or land at St. Mary's 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 St. Mary's Airport (KSM) is Cape Town International Airport (CPT), which is located 10,494 miles (16,889 kilometers) away in Cape Town, South Africa.

- The closest airport to Asmara International Airport (ASM) is Massawa International Airport (MSW), which is located 41 miles (66 kilometers) NE of ASM.
- During World War II, the airport was nearly destroyed by the British.
- Because of Asmara International Airport's high elevation of 7,661 feet, planes must typically fly at a faster airspeed in order to takeoff or land at ASM.
