About this route:
A direct, nonstop flight between MoD St Athan (DGX), St Athan, Wales, United Kingdom and San Luis Valley Regional Airport (ALS), Alamosa, Colorado, United States would travel a Great Circle distance of 4,725 miles (or 7,603 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 San Luis Valley Regional 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 San Luis Valley Regional Airport. You'll see that it will travel the same route of the red line on this map!

Facts about MoD St Athan (DGX):
- 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.
- MoD St Athan (DGX) currently has only 1 runway.
- 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.
- 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.
- In March 2004, however, DARA announced the loss of 550 jobs at St Athan as part of streamlining to make DARA more efficient and better able to compete with the private sector for lucrative aircraft repair contracts, but also because they lost out to a direct RAF bid for a contract to upgrade the air force's fleet of ageing Harrier jump jet aircraft.
- 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.
- In 2009 building work was due to commence on a new defence training academy with its heart at St Athan.
- The new academy was claimed to create up to 5000 jobs at St Athan with a £14 billion investment over 25 years with an estimated £57.4 million spent into the local economy.
- Just before 1100 GMT on 11 February 2009, two Grob Tutor aircraft flying out of St Athan were involved in a mid-air collision in which two Air Training Corps cadets and their instructors, both RAF pilots, died.
- After the war, airmen of the Airframe and Engine trades continued to train at St Athan, but in 1955 this training dispersed to RAF Kirkham and RAF Weeton.
- 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 continued to negotiate the project with the Metrix Consortium, but the price rose several times, reaching £14 billion in mid-2009.
Facts about San Luis Valley Regional Airport (ALS):
- In addition to being known as "San Luis Valley Regional Airport", another name for ALS is "Bergman Field".
- The furthest airport from San Luis Valley Regional Airport (ALS) is Sir Gaëtan Duval Airport (RRG), which is located 11,054 miles (17,790 kilometers) away in Rodrigues Island, Mauritius.
- San Luis Valley Regional Airport (ALS) has 2 runways.
- The closest airport to San Luis Valley Regional Airport (ALS) is Stevens Field (FAA: PSO) (PGO), which is located 66 miles (106 kilometers) W of ALS.
- Because of San Luis Valley Regional Airport's high elevation of 7,539 feet, planes must typically fly at a faster airspeed in order to takeoff or land at ALS. Combined with a high temperature, this could make ALS a "Hot & High" airport, where the air density is lower than it would otherwise be at sea level.
