About this route:
A direct, nonstop flight between Brown Field Municipal Airport (SDM), San Diego, California, United States and Amedee Army AirfieldReno Army Air Base Auxiliary Flight Strip (AHC), Herlong, California, United States would travel a Great Circle distance of 560 miles (or 901 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 Brown Field Municipal Airport and Amedee Army AirfieldReno Army Air Base Auxiliary Flight Strip, the route shown on this map most likely still appears to be a straight line.
