Nonstop flight route between Johannesburg, South Africa and San Juan Island, Washington, United States:

About this route:

A direct, nonstop flight between Grand Central Airport (GCJ), Johannesburg, South Africa and Roche Harbor Seaplane Base (RCE), San Juan Island, Washington, United States would travel a Great Circle distance of 10,241 miles (or 16,481 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 Grand Central Airport 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 Grand Central Airport and Roche Harbor Seaplane Base. You'll see that it will travel the same route of the red line on this map!

Facts about Grand Central Airport (GCJ):

• Because of Grand Central Airport's high elevation of 5,327 feet, planes must typically fly at a faster airspeed in order to takeoff or land at GCJ. Combined with a high temperature, this could make GCJ a "Hot & High" airport, where the air density is lower than it would otherwise be at sea level.
• The closest airport to Grand Central Airport (GCJ) is O. R. Tambo International Airport (JNB), which is located only 12 miles (20 kilometers) SSE of GCJ.
• Grand Central is a fully equipped airfield and is open 24 hours a day.

• Grand Central Airport (GCJ) currently has only 1 runway.

Facts about Roche Harbor Seaplane Base (RCE):

• 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.
• 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.
• Roche Harbor Seaplane Base (RCE) has 2 runways.
• 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.
