Nonstop flight route between Tacoma, Washington, United States and Siena, Italy:

About this route:

A direct, nonstop flight between McChord Field/McChord AFB (TCM), Tacoma, Washington, United States and Siena-Ampugnano Airport (SAY), Siena, Italy would travel a Great Circle distance of 5,583 miles (or 8,985 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 McChord Field/McChord AFB and Siena-Ampugnano 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 McChord Field/McChord AFB and Siena-Ampugnano Airport. You'll see that it will travel the same route of the red line on this map!
