About this route:
A direct, nonstop flight between RAF Ascension (ASI), Georgetown, Ascension Island, Saint Helena and Amook Bay Seaplane Base (AOS), Amook Bay, Alaska, United States would travel a Great Circle distance of 8,390 miles (or 13,502 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 RAF Ascension and Amook Bay 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 RAF Ascension and Amook Bay Seaplane Base. You'll see that it will travel the same route of the red line on this map!

- The NASA Tracking Station at Devil's Ashpit and the Cable & Wireless Earth Station at Donkey Plain were built in the "mid-sixties" for space operations and communications, including the latter's use for transmitting "microwave borne data via the Early Bird Satellite back to the NASA facility at Andover, Maine.
- In addition to being known as "RAF Ascension", another name for ASI is "Wideawake Airbase/Field".
- Ascension serves as a diversion airport for ETOPS aircraft crossing the Atlantic.
- The furthest airport from RAF Ascension (ASI) is Ujae Airport (UJE), which is nearly antipodal to RAF Ascension (meaning RAF Ascension is almost on the exact opposite side of the Earth from Ujae Airport), and is located 12,370 miles (19,907 kilometers) away in Ujae Atoll, Marshall Islands.
Facts about Amook Bay Seaplane Base (AOS):
- The closest airport to Amook Bay Seaplane Base (AOS) is Zachar Bay Seaplane Base (KZB), which is located only 6 miles (10 kilometers) NNE of AOS.
- The furthest airport from Amook Bay Seaplane Base (AOS) is Port Elizabeth International Airport (PLZ), which is located 10,814 miles (17,403 kilometers) away in Port Elizabeth, South Africa.
- In addition to being known as "Amook Bay Seaplane Base", another name for AOS is "AK81".
- Amook Bay Seaplane Base (AOS) currently has only 1 runway.
- Amook Bay Seaplane Base has one seaplane landing area designated N/S with a water surface measuring 8,000 by 700 feet.
- Because of Amook Bay Seaplane Base's relatively low elevation of 0 feet, planes can take off or land at Amook Bay 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.
