About this route:
A direct, nonstop flight between Smithton Airport (SIO), Smithton, Tasmania, Australia and McChord Field/McChord AFB (TCM), Tacoma, Washington, United States would travel a Great Circle distance of 8,297 miles (or 13,352 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 Smithton Airport and McChord Field/McChord AFB, 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 Smithton Airport and McChord Field/McChord AFB. You'll see that it will travel the same route of the red line on this map!
