Nonstop flight route between Wilmington, Ohio, United States and Den Helder, Netherlands:

About this route:

A direct, nonstop flight between Wilmington Air Park (ILN), Wilmington, Ohio, United States and De Kooy Airfield (DHR), Den Helder, Netherlands would travel a Great Circle distance of 4,061 miles (or 6,536 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 Wilmington Air Park and De Kooy Airfield, 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 Wilmington Air Park and De Kooy Airfield. You'll see that it will travel the same route of the red line on this map!

• Because of De Kooy Airfield's relatively low elevation of 4 feet, planes can take off or land at De Kooy Airfield 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.
