Nonstop flight route between Pituffik, Greenland and Alamosa, Colorado, United States:

About this route:

A direct, nonstop flight between Thule Air Base (THU), Pituffik, Greenland and San Luis Valley Regional Airport (ALS), Alamosa, Colorado, United States would travel a Great Circle distance of 2,929 miles (or 4,714 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 San Luis Valley Regional 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 San Luis Valley Regional Airport. You'll see that it will travel the same route of the red line on this map!

• Knud Rasmussen was the first to recognize the Pituffik plain as ideal for an airport.
• The closest airport to Thule Air Base (THU) is Savissivik Heliport (SVR), which is located 69 miles (111 kilometers) ESE of THU.
• In 1954, the 378 m Globecom Tower, a tower for military radio communication, was built at Northmountain.

Combined with a high temperature, this could make ALS a "Hot & High" airport, where the air density is lower than it would otherwise be at sea level.
• In addition to being known as "San Luis Valley Regional Airport", another name for ALS is "Bergman Field".
