Nonstop flight route between Mountain View, California, United States and Seoul, South Korea:

About this route:

A direct, nonstop flight between Moffett Federal Airfield (NUQ), Mountain View, California, United States and Gimpo International Airport (SEL), Seoul, South Korea would travel a Great Circle distance of 5,650 miles (or 9,093 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 Moffett Federal Airfield and Gimpo 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 Moffett Federal Airfield and Gimpo International Airport. You'll see that it will travel the same route of the red line on this map!

This is because the air density is higher closer to sea level than it would otherwise be at higher elevations.
• The adjacent NASA Ames Research Center is also home to several wind tunnels, including the Unitary Plan Wind Tunnel, and the National Full-Scale Aerodynamic Complex.
• The closest airport to Moffett Federal Airfield (NUQ) is Palo Alto Airport of Santa Clara County (PAO), which is located only 5 miles (8 kilometers) NW of NUQ.
