Nonstop flight route between Bongao, Tawi-Tawi, Philippines and Fort Sill, Oklahoma, United States:

About this route:

A direct, nonstop flight between Sanga-Sanga Airport (TWT), Bongao, Tawi-Tawi, Philippines and Henry Post Army Airfield (FSI), Fort Sill, Oklahoma, United States would travel a Great Circle distance of 8,738 miles (or 14,063 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 Sanga-Sanga Airport and Henry Post Army 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 Sanga-Sanga Airport and Henry Post Army Airfield. You'll see that it will travel the same route of the red line on this map!
