About this route:
A direct, nonstop flight between Andersen Air Force Base (UAM), Agana, Guam and St Helens Airport (HLS), St. Helens, Tasmania, Australia would travel a Great Circle distance of 3,801 miles (or 6,116 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 Andersen Air Force Base and St Helens 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 Andersen Air Force Base and St Helens Airport. You'll see that it will travel the same route of the red line on this map!

Facts about Andersen Air Force Base (UAM):
- 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.
- In 1951, the Strategic Air Command chose several overseas bases to support rotational unit deployments of its bombers from stateside bases, starting with B-29 Superfortress units and later including Convair B-36, B-47 Stratojet, B-50 Superfortress bombers, and KB-29 refueling tankers.
- The Strategic Air Command continued its 90-day unit rotational training program, and began to take over control over the base from the FEAF.
- The closest airport to Andersen Air Force Base (UAM) is Guam International Airport (GUM), which is located only 11 miles (17 kilometers) SW of UAM.
- The first host unit at North Field was the 314th Bombardment Wing, XXI Bomber Command, Twentieth Air Force.
- 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.
- The frequent bombings resulted in a cease-fire in Vietnam, but the B-52s continued to fly missions over Cambodia and Laos until those were halted on 15 August 1973.
Facts about St Helens Airport (HLS):
- Because of St Helens Airport's relatively low elevation of 158 feet, planes can take off or land at St Helens Airport 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.
- St Helens Airport (HLS) currently has only 1 runway.
- The closest airport to St Helens Airport (HLS) is Launceston Airport (LST), which is located 57 miles (92 kilometers) WSW of HLS.
- The furthest airport from St Helens Airport (HLS) is Corvo Airport (CVU), which is nearly antipodal to St Helens Airport (meaning St Helens Airport is almost on the exact opposite side of the Earth from Corvo Airport), and is located 12,317 miles (19,823 kilometers) away in Corvo Island, Azores, Portugal.
