Nonstop flight route between St Athan, Wales, United Kingdom and Hagåtña, Guam:

About this route:

A direct, nonstop flight between MoD St Athan (DGX), St Athan, Wales, United Kingdom and Guam International Airport (GUM), Hagåtña, Guam would travel a Great Circle distance of 7,564 miles (or 12,174 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 Guam International 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 Guam International Airport. You'll see that it will travel the same route of the red line on this map!

• 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.

• 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.
