About this route:
A direct, nonstop flight between Lympne Airport (LYM), Lympne, Kent, England, United Kingdom and Roundup Airport (RPX), Roundup, Montana, United States would travel a Great Circle distance of 4,506 miles (or 7,251 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 Lympne Airport and Roundup 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 Lympne Airport and Roundup Airport. You'll see that it will travel the same route of the red line on this map!
