About this route:
A direct, nonstop flight between Montgomery County Airpark (GAI), Gaithersburg, Maryland, United States and Hilton Head Airport (HHH), Hilton Head Island, South Carolina, United States would travel a Great Circle distance of 519 miles (or 835 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 Montgomery County Airpark and Hilton Head Airport, the route shown on this map most likely still appears to be a straight line.
