Nonstop flight route between St Athan, Wales, United Kingdom and Novato, California, United States:

About this route:

A direct, nonstop flight between MoD St Athan (DGX), St Athan, Wales, United Kingdom and Marin County Airport (NOT), Novato, California, United States would travel a Great Circle distance of 5,243 miles (or 8,437 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 MoD St Athan 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 MoD St Athan and Marin County Airport. You'll see that it will travel the same route of the red line on this map!

Facts about MoD St Athan (DGX):

• The furthest airport from MoD St Athan (DGX) is Dunedin International Airport (DUD), which is located 11,960 miles (19,248 kilometers) away in Dunedin, Otago, New Zealand.
• On 26 August 1993 an ATC civilian instructor was seriously injured and the RAF Volunteer Reserve pilot, Group Captain Roger Sweatman, was killed when their Chipmunk trainer, on an air experience flight, crashed after encountering difficulties during a simulated emergency low-height manoeuvre on take-off.
• St Athan also became the major RAF maintenance base for Vulcan, Victor, Buccaner, Phantom, Harrier, Tornado, Jaguar, Hawk and VC10 aircraft, originally under direct RAF control, but latterly under the auspices of the Defence Aviation Repair Agency.
• Because of MoD St Athan's relatively low elevation of 163 feet, planes can take off or land at MoD St Athan 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 MoD St Athan (DGX) is Cardiff Airport (CWL), which is located only 4 miles (6 kilometers) E of DGX.
• The MOD later decided that DARA's 'Fast Jets' and 'Engines' businesses would close by April 2007, although the 'Large Aircraft' business would continue and, on 14 April 2005, the Project Red Dragon super-hangar opened and DARA moved its VC10 operations from its existing 'Twin Peaks' hangar into the new facility.
• MoD St Athan (DGX) currently has only 1 runway.
• The base has been home to the RAF No.

Facts about Marin County Airport (NOT):

• Typical left traffic pattern 13 landings during high crosswinds are flown through varying rotor wind turbulence on the backside of Burdell Mountain and a relatively constant crosswind near the ground.
• Marin County Airport or Gnoss Field, formerly O56, is a public airport two miles northeast of Novato.
• Marin County Airport (NOT) currently has only 1 runway.
• 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.
• Gnoss Field celebrated its 50-year anniversary in 2009–2010.
• 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.
• The Wrights original privately owned airport had a dirt runway and was just west of the current airport, in what is now a grassy field.
• 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.
• In addition to being known as "Marin County Airport", other names for NOT include "Gnoss Field" and "DVO".
• Somehow Gnoss's single runway is laid out almost exactly perpendicular to the prevailing offshore west winds.
