Nonstop flight route between Patuxent River, Maryland, United States and Qamdo Prefecture, Tibet Autonomous Region, China:

About this route:

A direct, nonstop flight between Naval Air Station Patuxent River (NHK), Patuxent River, Maryland, United States and Qamdo Bamda Airport (BPX), Qamdo Prefecture, Tibet Autonomous Region, China would travel a Great Circle distance of 7,662 miles (or 12,331 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 Naval Air Station Patuxent River and Qamdo Bamda 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 Naval Air Station Patuxent River and Qamdo Bamda Airport. You'll see that it will travel the same route of the red line on this map!
