Nonstop flight route between Tacoma, Washington, United States and Ulan Bator, Mongolia:

About this route:

A direct, nonstop flight between Gray Army Airfield (GRF), Tacoma, Washington, United States and Chinggis Khaan International Airport (ULN), Ulan Bator, Mongolia would travel a Great Circle distance of 5,238 miles (or 8,430 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 Chinggis Khaan International 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 Gray Army Airfield and Chinggis Khaan International Airport. You'll see that it will travel the same route of the red line on this map!

Facts about Gray Army Airfield (GRF):

• World War II cantonment construction involved the demolition of some of the pre-1941 buildings.
• 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 closest airport to Gray Army Airfield (GRF) is McChord Field/McChord AFB (TCM), which is located only 6 miles (10 kilometers) NE of GRF.
• During the Vietnam War, GAAF not only trained helicopter units, but fixed-wing aircraft units as well.
• Company A, 5th Battalion, 159th Aviation Regiment, conducts high-altitude search-and-rescue operations.
• Camp Lewis advocates pushed for it to be a major dirigible and fixed-wing field.
• 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 addition to being known as "Gray Army Airfield", another name for GRF is "(Joint Base Lewis-McChord)".
• The furthest airport from Gray Army Airfield (GRF) is Tôlanaro Airport (FTU), which is located 10,809 miles (17,395 kilometers) away in Tôlanaro, Madagascar.

• Because of Chinggis Khaan International Airport's high elevation of 4,364 feet, planes must typically fly at a faster airspeed in order to takeoff or land at ULN. Combined with a high temperature, this could make ULN a "Hot & High" airport, where the air density is lower than it would otherwise be at sea level.
• The furthest airport from Chinggis Khaan International Airport (ULN) is Cochrane Airfield (LGR), which is nearly antipodal to Chinggis Khaan International Airport (meaning Chinggis Khaan International Airport is almost on the exact opposite side of the Earth from Cochrane Airfield), and is located 12,386 miles (19,933 kilometers) away in Cochrane, Chile.
