Nonstop flight route between Waterfall, Alaska, United States and Zhoushan, Zhejiang, China:

About this route:

A direct, nonstop flight between Waterfall Seaplane Base (KWF), Waterfall, Alaska, United States and Zhoushan Putuoshan Airport (HSN), Zhoushan, Zhejiang, China would travel a Great Circle distance of 5,064 miles (or 8,149 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 Waterfall Seaplane Base and Zhoushan Putuoshan 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 Waterfall Seaplane Base and Zhoushan Putuoshan Airport. You'll see that it will travel the same route of the red line on this map!

• Because of Waterfall Seaplane Base's relatively low elevation of 0 feet, planes can take off or land at Waterfall Seaplane Base 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 furthest airport from Waterfall Seaplane Base (KWF) is Port Alfred Airport (AFD), which is located 10,657 miles (17,150 kilometers) away in Port Alfred, South Africa.

Facts about Zhoushan Putuoshan Airport (HSN):

• The furthest airport from Zhoushan Putuoshan Airport (HSN) is Monte Caseros Airport (MCS), which is nearly antipodal to Zhoushan Putuoshan Airport (meaning Zhoushan Putuoshan Airport is almost on the exact opposite side of the Earth from Monte Caseros Airport), and is located 12,413 miles (19,977 kilometers) away in Monte Caseros, Corrientes, Argentina.
• Across the entire site which was about 3,200m x 400m, a matrix of 150mm perforated iron pipes at 10m centers in both directions was installed vertically, in a manner that allowed the Chinese to pour water and sand down the pipes to help with the compacting.
• The closest airport to Zhoushan Putuoshan Airport (HSN) is Ningbo Lishe International Airport (NGB), which is located 54 miles (88 kilometers) W of HSN.
• An interesting fact relating to the design of the runway is that the existing site, which was a large area of rice paddy fields, was less than a half-meter above sea level, situated behind a protective dam which kept seawater out during severe weather.
• In addition to being known as "Zhoushan Putuoshan Airport", other names for HSN include "舟山普陀山机场" and "Zhōushān Pǔtuóshān Jīchǎng".
