About this route:
A direct, nonstop flight between Fort Simpson Airport (YFS), Fort Simpson, Northwest Territories, Canada and Lackland Air Force Base Joint Base San Antonio (SKF), San Antonio, Texas, United States would travel a Great Circle distance of 2,462 miles (or 3,962 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 Fort Simpson Airport and Lackland Air Force Base Joint Base San Antonio, the route shown on this map most likely still appears to be a straight line.
