About this route:
A direct, nonstop flight between Ashburton Aerodrome (ASG), Ashburton, New Zealand and Andersen Air Force Base (UAM), Agana, Guam would travel a Great Circle distance of 4,318 miles (or 6,949 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 Ashburton Aerodrome and Andersen Air Force Base, 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 Ashburton Aerodrome and Andersen Air Force Base. You'll see that it will travel the same route of the red line on this map!

Facts about Ashburton Aerodrome (ASG):
- Ashburton Aerodrome (ASG) has 4 runways.
- The furthest airport from Ashburton Aerodrome (ASG) is A Coruña Airport (LCG), which is nearly antipodal to Ashburton Aerodrome (meaning Ashburton Aerodrome is almost on the exact opposite side of the Earth from A Coruña Airport), and is located 12,394 miles (19,947 kilometers) away in A Coruña, Spain.
- Because of Ashburton Aerodrome's relatively low elevation of 298 feet, planes can take off or land at Ashburton Aerodrome 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 Ashburton Aerodrome (ASG) is Richard Pearse Airport (Timaru Airport) (TIU), which is located 40 miles (64 kilometers) SW of ASG.
Facts about Andersen Air Force Base (UAM):
- Andersen AFB was established in 1944 as North Field and is named for Brigadier General James Roy Andersen.

- However, the FEAF Bomber Command was inactivated in 1954 and its three B-29 wings returned stateside and replaced with B-47s.
- Andersen Air Force Base's origins begin on 7 December 1941 when Guam was attacked by the armed forces of Imperial Japan in the Battle of Guam three hours after the Attack on Pearl Harbor.
- B-29 Superfortress missions from North Field were attacks against strategic targets in Japan, initially operating in daylight and at high altitude to bomb factories, refineries, and other objectives.
- The furthest airport from Andersen Air Force Base (UAM) is Salvador-Deputado Luís Eduardo Magalhães International Airport (2 de Julho) (SSA), which is nearly antipodal to Andersen Air Force Base (meaning Andersen Air Force Base is almost on the exact opposite side of the Earth from Salvador-Deputado Luís Eduardo Magalhães International Airport (2 de Julho)), and is located 12,214 miles (19,656 kilometers) away in Salvador, Bahia, Brazil.
