About this route:
A direct, nonstop flight between Chester County G. O. Carlson Airport (CTH), Coatesville, Pennsylvania, United States and Half Moon Bay AirportHalf Moon Bay Flight Strip (HAF), Half Moon Bay, California, United States would travel a Great Circle distance of 2,490 miles (or 4,007 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 Chester County G. O. Carlson Airport and Half Moon Bay AirportHalf Moon Bay Flight Strip, the route shown on this map most likely still appears to be a straight line.
