Nonstop flight route between Den Helder, Netherlands and Trona, California, United States:

About this route:

A direct, nonstop flight between De Kooy Airfield (DHR), Den Helder, Netherlands and Trona Airport (TRH), Trona, California, United States would travel a Great Circle distance of 5,393 miles (or 8,679 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 De Kooy Airfield and Trona 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 De Kooy Airfield and Trona Airport. You'll see that it will travel the same route of the red line on this map!

• Most movements on the De Kooy are made by helicopters, bringing workers to and from offshore oilrigs and naval helicopters such as the Westland Lynx or NH90 of the Royal Netherlands Navy.
• The oil fields in the North Sea will eventually be depleted and when that happens the airport would lose most of its helicopter movements and thus alternative markets are being looked at, such as business and holiday flights.
