About this route:
A direct, nonstop flight between MoD St Athan (DGX), St Athan, Wales, United Kingdom and Tonopah Airport (TPH), Tonopah, Nevada, United States would travel a Great Circle distance of 5,075 miles (or 8,168 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 Tonopah 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 Tonopah Airport. You'll see that it will travel the same route of the red line on this map!

Facts about MoD St Athan (DGX):
- RAF St Athan was also home for the Royal Air Force Administrative Apprentice Training School.
- 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.
- 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.
- 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.
- The closest airport to MoD St Athan (DGX) is Cardiff Airport (CWL), which is located only 4 miles (6 kilometers) E of DGX.
- The training to be carried out at St Athan was to be specialist phase 2 and phase 3 engineering courses of the Royal Navy, Army and Royal Air Force.
- 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.
- MoD St Athan (DGX) currently has only 1 runway.
- 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 Tonopah Airport's high elevation of 5,430 feet, planes must typically fly at a faster airspeed in order to takeoff or land at TPH. Combined with a high temperature, this could make TPH a "Hot & High" airport, where the air density is lower than it would otherwise be at sea level.
- Tonopah Airport (TPH) has 2 runways.
