Nonstop flight route between Boulder, Colorado, United States and Changi, Singapore:

About this route:

A direct, nonstop flight between Boulder Municipal Airport (WBU), Boulder, Colorado, United States and Singapore Changi Airport (SIN), Changi, Singapore would travel a Great Circle distance of 9,034 miles (or 14,539 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 Boulder Municipal Airport and Singapore Changi 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 Boulder Municipal Airport and Singapore Changi Airport. You'll see that it will travel the same route of the red line on this map!

Facts about Singapore Changi Airport (SIN):

• Because of Singapore Changi Airport's relatively low elevation of 22 feet, planes can take off or land at Singapore Changi 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.
• Announced on 19 August 2013 by Changi Airport Group, a new mixed-use complex will be developed on the car park site fronting Terminal 1 and will optimise the use of the 3.5-hectare plot of land.
