Nonstop flight route between Pituffik, Greenland and Île Sainte-Marie, Madagascar:

About this route:

A direct, nonstop flight between Thule Air Base (THU), Pituffik, Greenland and Sainte Marie Airport (SMS), Île Sainte-Marie, Madagascar would travel a Great Circle distance of 7,814 miles (or 12,575 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 Sainte Marie 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 Sainte Marie Airport. You'll see that it will travel the same route of the red line on this map!

• 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.

This is because the air density is higher closer to sea level than it would otherwise be at higher elevations.
• Sainte Marie Airport (SMS) currently has only 1 runway.
