About this route:
A direct, nonstop flight between Flabob Airport (RIR), Riverside/Rubidoux, California, United States and Henry Post Army Airfield (FSI), Fort Sill, Oklahoma, United States would travel a Great Circle distance of 1,084 miles (or 1,745 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 relatively short distance between Flabob Airport and Henry Post Army Airfield, the route shown on this map most likely still appears to be a straight line.
