About this route:
A direct, nonstop flight between Angoon Seaplane Base (AGN), Angoon, Alaska, United States and RAF Ascension (ASI), Georgetown, Ascension Island, Saint Helena would travel a Great Circle distance of 7,781 miles (or 12,522 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 Angoon Seaplane Base and RAF Ascension, 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 Angoon Seaplane Base and RAF Ascension. You'll see that it will travel the same route of the red line on this map!

- Angoon Seaplane Base (AGN) currently has only 1 runway.
- Because of Angoon Seaplane Base's relatively low elevation of 0 feet, planes can take off or land at Angoon 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 closest airport to Angoon Seaplane Base (AGN) is Chatham Seaplane Base (CYM), which is located only 13 miles (22 kilometers) W of AGN.
- Angoon Seaplane Base has one seaplane landing area designated NW/SE which measures 10,000 by 900 feet.
