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

About this route:

A direct, nonstop flight between Wright-Patterson Air Force Base (FFO), Dayton, Ohio, United States and De Kooy Airfield (DHR), Den Helder, Netherlands would travel a Great Circle distance of 4,052 miles (or 6,521 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 Wright-Patterson Air Force Base 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 Wright-Patterson Air Force Base and De Kooy Airfield. You'll see that it will travel the same route of the red line on this map!

• Wright-Patterson AFB is "one of the largest, most diverse, and organizationally complex bases in the Air Force" with a long history of flight test spanning from the Wright Brothers into the Space Age.
• In 1954, 465 acres of land adjacent to the Mad River at the northeast boundary of the base, near the former location of the village of Osborn, were purchased for a Strategic Air Command dispersal site.
• The host unit at Wright-Patterson AFB is the 88th Air Base Wing, assigned to the Air Force Life Cycle Management Center and Air Force Materiel Command.
• In addition to being known as "Wright-Patterson Air Force Base", another name for FFO is "Wright-Patterson AFB".
• It is also the home base of the 445th Airlift Wing of the Air Force Reserve Command, an Air Mobility Command-gained unit which flies the C-17 Globemaster heavy airlifter.

• 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.
• 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.
• The closest airport to De Kooy Airfield (DHR) is Amsterdam Airport Schiphol (AMS), which is located 43 miles (68 kilometers) S of DHR.
