About this route:
A direct, nonstop flight between Johnston Atoll Airport (JON), Johnston Atoll, U.S. Minor Outlying Islands and St. Catharines/Niagara District Airport (YCM), St. Catharines, Ontario, Canada would travel a Great Circle distance of 5,451 miles (or 8,773 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 large distance between Johnston Atoll Airport and St. Catharines/Niagara District Airport, the route shown on this map most likely appears curved because of this reason.
Try it at home! Get a globe and tightly lay a string between Johnston Atoll Airport and St. Catharines/Niagara District Airport. You'll see that it will travel the same route of the red line on this map!
