About this route:
A direct, nonstop flight between Otis Air National Guard Base Coast Guard Air Station Cape Cod (FMH), Falmouth, Massachusetts, United States and Washington Dulles International Airport (IAD), Washington, D.C. / Virginia, United States would travel a Great Circle distance of 411 miles (or 661 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 Otis Air National Guard Base Coast Guard Air Station Cape Cod and Washington Dulles International Airport, the route shown on this map most likely still appears to be a straight line.
