About this route:
A direct, nonstop flight between Palm Springs International AirportPalm Springs Army Airfield (PSP), Palm Springs, California, United States and St. Louis Regional Airport (ALN), Alton, Illinois, United States would travel a Great Circle distance of 1,507 miles (or 2,426 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 Palm Springs International AirportPalm Springs Army Airfield and St. Louis Regional Airport, the route shown on this map most likely still appears to be a straight line.
