About this route:
A direct, nonstop flight between Andersen Air Force Base (UAM), Agana, Guam and Gray Army Airfield (GRF), Tacoma, Washington, United States would travel a Great Circle distance of 5,650 miles (or 9,092 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 Gray Army Airfield, 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 Gray Army Airfield. You'll see that it will travel the same route of the red line on this map!

Facts about Andersen Air Force Base (UAM):
- 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 base returned to routine operations by the late 1970s, but continued to serve as one of SAC's strategic locations.
- 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.
- Andersen Air Force Base was established on 3 December 1944 and is named for Brigadier General James Roy Andersen.
- 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.
- However, the FEAF Bomber Command was inactivated in 1954 and its three B-29 wings returned stateside and replaced with B-47s.
- 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.
Facts about Gray Army Airfield (GRF):
- The closest airport to Gray Army Airfield (GRF) is McChord Field/McChord AFB (TCM), which is located only 6 miles (10 kilometers) NE of GRF.
- Another innovative aircraft came to GAAF in the fall of 2000.
- In addition to being known as "Gray Army Airfield", another name for GRF is "(Joint Base Lewis-McChord)".
- Camp Lewis advocates pushed for it to be a major dirigible and fixed-wing field.
- The 1938 construction included two paved runways, a boiler plant, headquarters building, metal balloon hangar, six-plane hangar, corrugated-iron hangar, storehouse, flight-surgeon office, and film-storage building.
- The furthest airport from Gray Army Airfield (GRF) is Tôlanaro Airport (FTU), which is located 10,809 miles (17,395 kilometers) away in Tôlanaro, Madagascar.
- Reactivated following service in Vietnam, the 9th Infantry Division aviation units occupied GAAF in 1972.
- Because of Gray Army Airfield's relatively low elevation of 300 feet, planes can take off or land at Gray Army Airfield 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.
- Gray Army Airfield (GRF) currently has only 1 runway.
- The Air Transport Command.
