Nonstop flight route between Ulan Bator, Mongolia and Shemya, Alaska, United States:

About this route:

A direct, nonstop flight between Chinggis Khaan International Airport (ULN), Ulan Bator, Mongolia and Eareckson Air Station (SYA), Shemya, Alaska, United States would travel a Great Circle distance of 2,883 miles (or 4,639 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 Chinggis Khaan International Airport and Eareckson Air Station, 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 Chinggis Khaan International Airport and Eareckson Air Station. You'll see that it will travel the same route of the red line on this map!

Combined with a high temperature, this could make ULN a "Hot & High" airport, where the air density is lower than it would otherwise be at sea level.
• The terminal was upgraded to make it suitable for international traffic in 1986.
• The airport was first established as Buyant-Ukhaa airport on 19 February 1957.
• The furthest airport from Chinggis Khaan International Airport (ULN) is Cochrane Airfield (LGR), which is nearly antipodal to Chinggis Khaan International Airport (meaning Chinggis Khaan International Airport is almost on the exact opposite side of the Earth from Cochrane Airfield), and is located 12,386 miles (19,933 kilometers) away in Cochrane, Chile.

• Because of Eareckson Air Station's relatively low elevation of 97 feet, planes can take off or land at Eareckson Air Station 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.
• In addition to being known as "Eareckson Air Station", other names for SYA include "Shemya Air Force Base", "Shemya Army Airfield" and "  ".
• In 1958, the Air Force resumed operations on Shemya in support of various Air Force and Army strategic intelligence collection activities.
