About this route:
A direct, nonstop flight between Johnston Atoll Airport (JON), Johnston Atoll, U.S. Minor Outlying Islands and Mammoth Yosemite Airport (MMH), Mammoth Lakes, California, United States would travel a Great Circle distance of 3,385 miles (or 5,447 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 Johnston Atoll Airport and Mammoth Yosemite 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 Johnston Atoll Airport and Mammoth Yosemite Airport. You'll see that it will travel the same route of the red line on this map!

Facts about Johnston Atoll Airport (JON):
- In July 1942 the civilian contractors at the atoll were replaced by 500 men from the 5th and 10th Naval Construction Battalions, who expanded the fuel storage and water production at the base and built additional facilities.
- The closest airport to Johnston Atoll Airport (JON) is PMRF Barking Sands (BKH), which is located 733 miles (1,179 kilometers) ENE of JON.
- Because of Johnston Atoll Airport's relatively low elevation of 7 feet, planes can take off or land at Johnston Atoll 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.
- The furthest airport from Johnston Atoll Airport (JON) is Lubango Mukanka Airport (SDD), which is nearly antipodal to Johnston Atoll Airport (meaning Johnston Atoll Airport is almost on the exact opposite side of the Earth from Lubango Mukanka Airport), and is located 12,195 miles (19,627 kilometers) away in Lubango, Angola.

- Because of Mammoth Yosemite Airport's high elevation of 7,135 feet, planes must typically fly at a faster airspeed in order to takeoff or land at MMH. Combined with a high temperature, this could make MMH a "Hot & High" airport, where the air density is lower than it would otherwise be at sea level.
- Mammoth Yosemite Airport (MMH) currently has only 1 runway.
