Nonstop flight route between Cat Lake, Ontario, Canada and Rapid City, South Dakota, United States:

About this route:

A direct, nonstop flight between Cat Lake Airport (YAC), Cat Lake, Ontario, Canada and Ellsworth Air Force Base (RCA), Rapid City, South Dakota, United States would travel a Great Circle distance of 737 miles (or 1,186 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 Cat Lake Airport and Ellsworth Air Force Base, the route shown on this map most likely still appears to be a straight line.
