Nonstop flight route between Rapid City, South Dakota, United States and Tresco, Isles of Scilly, United Kingdom:

About this route:

A direct, nonstop flight between Ellsworth Air Force Base (RCA), Rapid City, South Dakota, United States and Tresco Heliport (TSO), Tresco, Isles of Scilly, United Kingdom would travel a Great Circle distance of 4,241 miles (or 6,826 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 Ellsworth Air Force Base and Tresco Heliport, 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 Ellsworth Air Force Base and Tresco Heliport. You'll see that it will travel the same route of the red line on this map!

Facts about Tresco Heliport (TSO):

• The furthest airport from Tresco Heliport (TSO) is Dunedin International Airport (DUD), which is nearly antipodal to Tresco Heliport (meaning Tresco Heliport is almost on the exact opposite side of the Earth from Dunedin International Airport), and is located 12,116 miles (19,499 kilometers) away in Dunedin, Otago, New Zealand.
• The closest airport to Tresco Heliport (TSO) is St Mary's Airport (ISC), which is located only 3 miles (5 kilometers) SE of TSO.
• Because of Tresco Heliport's relatively low elevation of 20 feet, planes can take off or land at Tresco Heliport 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.
• Tresco's principal industry is tourism, and the heliport supported this by enabling scheduled helicopter service to and from the mainland.
