About this route:
A direct, nonstop flight between Andersen Air Force Base (UAM), Agana, Guam and St. Paul Island Airport (SNP), St. Paul Island, Alaska, United States would travel a Great Circle distance of 3,813 miles (or 6,136 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. Paul Island 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. Paul Island 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):
- Flying out of Guam, S/Sgt Henry E Erwin of the 29th Bombardment Group was awarded the Medal of Honor for action that saved his B-29 during a mission over Koriyama, Japan, on 12 April 1945.
- Andersen AFB was established in 1944 as North Field and is named for Brigadier General James Roy Andersen.
- Guam was considered as being ideal to establish air bases to launch B-29 Superfortress operations against the Japanese Home Islands.
- With the start of Operation Arc Light in June 1965, B-52s and KC-135s began regular bombing missions over Vietnam, and continued in that capacity until 1973, with a break between August 1970 and early 1972.
- The Japanese managed to contain the marines on two beachheads, but their counter-attack failed.
- At Andersen, the wing assumed responsibility for administering two active and one semi-active bases plus an assortment of communication, weather, radar, rescue and other facilities and units including the Marianas Air Material Area, a wing size unit.

- Because of St. Paul Island Airport's relatively low elevation of 63 feet, planes can take off or land at St. Paul Island 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.
