Nonstop flight route between San Francisco, California, United States and Imperatriz, Maranhão, Brazil:

About this route:

A direct, nonstop flight between San Francisco International Airport (SFO), San Francisco, California, United States and Imperatriz-Prefeito Renato Moreira Airport (IMP), Imperatriz, Maranhão, Brazil would travel a Great Circle distance of 5,637 miles (or 9,072 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 San Francisco International Airport and Imperatriz-Prefeito Renato Moreira 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 San Francisco International Airport and Imperatriz-Prefeito Renato Moreira Airport. You'll see that it will travel the same route of the red line on this map!
