Nonstop flight route between Tacoma, Washington, United States and Johnston Atoll, U.S. Minor Outlying Islands:

About this route:

A direct, nonstop flight between McChord Field/McChord AFB (TCM), Tacoma, Washington, United States and Johnston Atoll Airport (JON), Johnston Atoll, U.S. Minor Outlying Islands would travel a Great Circle distance of 3,392 miles (or 5,459 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 McChord Field/McChord AFB and Johnston Atoll 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 McChord Field/McChord AFB and Johnston Atoll Airport. You'll see that it will travel the same route of the red line on this map!

• Because of McChord Field/McChord AFB's relatively low elevation of 322 feet, planes can take off or land at McChord Field/McChord AFB 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 McChord Field/McChord AFB (TCM) is Gray Army Airfield (GRF), which is located only 6 miles (10 kilometers) SW of TCM.
• In addition to being known as "McChord Field/McChord AFB", another name for TCM is "Part of Air Mobility Command (AMC)".
