Nonstop flight route between Sisimiut, Greenland and Thorne Bay, Alaska, United States:

About this route:

A direct, nonstop flight between Sisimiut Airport (JHS), Sisimiut, Greenland and Thorne Bay Seaplane Base (KTB), Thorne Bay, Alaska, United States would travel a Great Circle distance of 2,528 miles (or 4,069 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 Sisimiut Airport and Thorne Bay Seaplane Base, 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 Sisimiut Airport and Thorne Bay Seaplane Base. You'll see that it will travel the same route of the red line on this map!

Facts about Sisimiut Airport (JHS):

• Sisimiut Airport handled 22,955 passengers last year.
• With 5,460 inhabitants as of 2010, Sisimiut is the second-largest town in Greenland, one of the few towns in the country exhibiting growth patterns, with corresponding increasing passenger traffic at Sisimiut Airport.
• Because of Sisimiut Airport's relatively low elevation of 33 feet, planes can take off or land at Sisimiut Airport 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.
• At the terminal there is a Post Greenland box, a soft drink machine and television, and a small exhibition from the Sisimiut Museum.
• In addition to being known as "Sisimiut Airport", other names for JHS include "Mittarfik Sisimiut" and "Sisimiut Lufthavn".
• The construction of Sisimiut Airport was part of the regional airport network extension in Greenland, with several airports built to serve STOL aircraft of Air Greenland − the venerable De Havilland Canada Dash-7s acquired in the preceding decade − planes particularly suited to the often severe weather conditions in Greenland.
• There is no deicing equipment at the airport, which is costly and problematic in Greenlandic winter.
• Sisimiut Airport is an airport located 2.2 NM northwest of Sisimiut, a town in the Qeqqata municipality in central-western Greenland.

Facts about Thorne Bay Seaplane Base (KTB):

• The closest airport to Thorne Bay Seaplane Base (KTB) is Hollis Clark Bay Seaplane Base (HYL), which is located only 14 miles (23 kilometers) SSW of KTB.
• Thorne Bay Seaplane Base has one seaplane landing area designated NW/SE with a water surface measuring 5,000 by 2,000 feet.
• The furthest airport from Thorne Bay Seaplane Base (KTB) is Port Alfred Airport (AFD), which is located 10,618 miles (17,088 kilometers) away in Port Alfred, South Africa.
• Thorne Bay Seaplane Base (KTB) currently has only 1 runway.
• Because of Thorne Bay Seaplane Base's relatively low elevation of 0 feet, planes can take off or land at Thorne Bay Seaplane Base 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.
