Nonstop flight route between Comiso, Italy and Denver, Colorado, United States:

About this route:

A direct, nonstop flight between Comiso Airport (CIY), Comiso, Italy and Denver International Airport (DEN), Denver, Colorado, United States would travel a Great Circle distance of 5,878 miles (or 9,460 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 Comiso Airport and Denver International 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 Comiso Airport and Denver International Airport. You'll see that it will travel the same route of the red line on this map!

• Because of Comiso Airport's relatively low elevation of 620 feet, planes can take off or land at Comiso Airport at a lower air speed than at airports located at a higher elevation. This is because the air density is higher closer to sea level than it would otherwise be at higher elevations.
• The closest airport to Comiso Airport (CIY) is Naval Air Station Sigonella (NSY), which is located 33 miles (53 kilometers) NNE of CIY.
• It became one of several key aerodromes in southern Sicily during World War II.
