About this route:

A direct, nonstop flight between Thule Air Base (THU), Pituffik, Greenland and Lemhi County Airport (SMN), Salmon, Idaho, United States would travel a Great Circle distance of 2,514 miles (or 4,046 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 Lemhi County 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 Lemhi County Airport. You'll see that it will travel the same route of the red line on this map!

  • In 1954, the 378 m Globecom Tower, a tower for military radio communication, was built at Northmountain.
  • Thule is the location where the fastest recorded sea level surface wind speed in the world was measured when a peak speed of 333 kilometres per hour was recorded on 8 March 1972 prior to the instrument's destruction.
  • Knud Rasmussen was the first to recognize the Pituffik plain as ideal for an airport.
  • The furthest airport from Thule Air Base (THU) is Hobart International Airport (HBA), which is located 9,883 miles (15,905 kilometers) away in Hobart, Tasmania, Australia.
