Nonstop flight route between Tacoma, Washington, United States and Den Helder, Netherlands:

About this route:

A direct, nonstop flight between Gray Army Airfield (GRF), Tacoma, Washington, United States and De Kooy Airfield (DHR), Den Helder, Netherlands would travel a Great Circle distance of 4,866 miles (or 7,830 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 Gray Army Airfield 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 Gray Army Airfield and De Kooy Airfield. You'll see that it will travel the same route of the red line on this map!

Facts about Gray Army Airfield (GRF):

• The 91st Observation Squadron and aircraft of the 3rd Balloon Squadron operated out of the Fort Lewis airfield.
• Because of Gray Army Airfield's relatively low elevation of 300 feet, planes can take off or land at Gray Army 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.
• In October 1921 Curtiss JN-4 “Jenny” biplanes flew from the Naval Station at Sand Point to a grass airfield at what was then called "Camp Lewis", located at a site just west of today’s Gray AAF.
• The 9th Cavalry Brigade in the 1980s developed air-assault strategies with their AH-1 Cobra helicopters based upon experiences learned in Vietnam.
• In addition to being known as "Gray Army Airfield", another name for GRF is "(Joint Base Lewis-McChord)".

• 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 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.
