About this route:
A direct, nonstop flight between Henry Post Army Airfield (FSI), Fort Sill, Oklahoma, United States and Region of Waterloo International Airport (YKF), Waterloo Regional Municipality, Ontario, Canada would travel a Great Circle distance of 1,139 miles (or 1,833 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 Henry Post Army Airfield and Region of Waterloo International Airport, the route shown on this map most likely still appears to be a straight line.
