Nonstop flight route between Agana, Guam and San Juan Island, Washington, United States:

About this route:

A direct, nonstop flight between Andersen Air Force Base (UAM), Agana, Guam and Roche Harbor Seaplane Base (RCE), San Juan Island, Washington, United States would travel a Great Circle distance of 5,604 miles (or 9,018 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 Andersen Air Force Base and Roche Harbor Seaplane Base, 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 Andersen Air Force Base and Roche Harbor Seaplane Base. You'll see that it will travel the same route of the red line on this map!

• In addition to being known as "Roche Harbor Seaplane Base", another name for RCE is "W39".
• The closest airport to Roche Harbor Seaplane Base (RCE) is Friday Harbor Seaplane Base (FBS), which is located only 8 miles (14 kilometers) SE of RCE.
• Because of Roche Harbor Seaplane Base's relatively low elevation of 0 feet, planes can take off or land at Roche Harbor 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 Roche Harbor Seaplane Base (RCE) is Tôlanaro Airport (FTU), which is located 10,722 miles (17,256 kilometers) away in Tôlanaro, Madagascar.
