Nonstop flight route between Georgetown, Ascension Island, Saint Helena and Novato, California, United States:

About this route:

A direct, nonstop flight between RAF Ascension (ASI), Georgetown, Ascension Island, Saint Helena and Marin County Airport (NOT), Novato, California, United States would travel a Great Circle distance of 7,543 miles (or 12,139 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 Marin County 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 RAF Ascension and Marin County Airport. You'll see that it will travel the same route of the red line on this map!

Facts about RAF Ascension (ASI):

• Ascension serves as a diversion airport for ETOPS aircraft crossing the Atlantic.
• In addition to being known as "RAF Ascension", another name for ASI is "Wideawake Airbase/Field".
• 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.
• In 1939 Ascension became important as a HF/DF radio station covering trade routes.
• Wideawake Airfield was a US installation built in 1943 by arrangement with the British government.
• 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.
• The closest airport to RAF Ascension (ASI) is Sasstown Airport (SAZ), which is located 965 miles (1,553 kilometers) NNE of ASI.

Facts about Marin County Airport (NOT):

• Marin County Airport (NOT) currently has only 1 runway.
• There is a plan to extend the length of Gnoss' runway by 1100', to 4400'.
• In addition to being known as "Marin County Airport", other names for NOT include "Gnoss Field" and "DVO".
• The furthest airport from Marin County Airport (NOT) is Tôlanaro Airport (FTU), which is located 11,343 miles (18,254 kilometers) away in Tôlanaro, Madagascar.
• The typical Gnoss Field crosswind landing conditions on runway 31 are a stronger than reported headwind on right base and, in a typical training aircraft, a slight amount of wind shear about 100 feet before the runway 31 threshold, settling down to a steady crosswind - but then adding to a slight headwind component, just past the near west side hangars.
• Because of Marin County Airport's relatively low elevation of 2 feet, planes can take off or land at Marin County Airport 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 Marin County Airport (NOT) is Napa County Airport (APC), which is located only 16 miles (25 kilometers) ENE of NOT.
• Somehow Gnoss's single runway is laid out almost exactly perpendicular to the prevailing offshore west winds.
