Nonstop flight route between Pituffik, Greenland and Ulan Bator, Mongolia:

About this route:

A direct, nonstop flight between Thule Air Base (THU), Pituffik, Greenland and Chinggis Khaan International Airport (ULN), Ulan Bator, Mongolia would travel a Great Circle distance of 3,841 miles (or 6,182 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 Thule Air Base and Chinggis Khaan 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 Thule Air Base and Chinggis Khaan International Airport. You'll see that it will travel the same route of the red line on this map!

• After the German occupation of Denmark on 9 April 1940, Henrik Kauffmann Danish Ambassador to the United States, made an agreement "In the name of the king" with the United States authorizing the United States to defend the Danish colonies on Greenland from German aggression - this agreement faced Kaufmann with a charge of high treason.

• Originally established as a Strategic Air Command installation, Thule would periodically serve as a dispersal base for B-36 Peacemaker and B-47 Stratojet aircraft during the 1950s, as well as providing an ideal site to test the operability and maintainability of these weapon systems in extreme cold weather.
• The ratification of the treaty in 1951 did not change much, except that the Danish national flag Dannebrog must be side by side with Stars and Stripes on the base.

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.
