About this route:
A direct, nonstop flight between MoD St Athan (DGX), St Athan, Wales, United Kingdom and Kemmerer Municipal Airport (EMM), Kemmerer, Wyoming, United States would travel a Great Circle distance of 4,657 miles (or 7,494 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 Kemmerer Municipal 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 Kemmerer Municipal Airport. You'll see that it will travel the same route of the red line on this map!

- 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 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.
- 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.
