Nonstop flight route between Zhoushan, Zhejiang, China and SeaTac (near Seattle and Tacoma), Washington, United States:

About this route:

A direct, nonstop flight between Zhoushan Putuoshan Airport (HSN), Zhoushan, Zhejiang, China and Seattle–Tacoma International Airport (SEA), SeaTac (near Seattle and Tacoma), Washington, United States would travel a Great Circle distance of 5,755 miles (or 9,261 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 Zhoushan Putuoshan Airport and Seattle–Tacoma 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 Zhoushan Putuoshan Airport and Seattle–Tacoma International Airport. You'll see that it will travel the same route of the red line on this map!

• At the end of the day the runway length was held to 8,200 which is too short for fully laden 747's to take off safely although it could be extended at sometime in the future if this was ever required.
• The Chinese engineers had a rather unique way of placing the fill which was regularly monitored by U.S.
