About this route:
A direct, nonstop flight between Tri-City Airport (PPF), Parsons, Kansas, United States and Sloulin Field International Airport (ISN), Williston, North Dakota, United States would travel a Great Circle distance of 854 miles (or 1,375 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 Tri-City Airport and Sloulin Field International Airport, the route shown on this map most likely still appears to be a straight line.
