About this route:
A direct, nonstop flight between St. Johns Industrial Air Park (SJN), St. Johns, Arizona, United States and McChord Field/McChord AFB (TCM), Tacoma, Washington, United States would travel a Great Circle distance of 1,105 miles (or 1,779 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 relatively short distance between St. Johns Industrial Air Park and McChord Field/McChord AFB, the route shown on this map most likely still appears to be a straight line.

Facts about St. Johns Industrial Air Park (SJN):
- St. Johns Industrial Air Park (SJN) has 2 runways.
- The closest airport to St. Johns Industrial Air Park (SJN) is Show Low Regional Airport (SOW), which is located 40 miles (64 kilometers) WSW of SJN.
- Because of St. Johns Industrial Air Park's high elevation of 5,737 feet, planes must typically fly at a faster airspeed in order to takeoff or land at SJN. Combined with a high temperature, this could make SJN a "Hot & High" airport, where the air density is lower than it would otherwise be at sea level.
- The furthest airport from St. Johns Industrial Air Park (SJN) is Sir Gaëtan Duval Airport (RRG), which is located 11,324 miles (18,225 kilometers) away in Rodrigues Island, Mauritius.
Facts about McChord Field/McChord AFB (TCM):
- On 28 February 1938 the airfield was officially transferred to the United States Government.
- During the International Geophysical Year 1957–1958, and subsequently through 1962 the 62d TCW supported scientific stations in the Arctic Ocean by airlanding and airdropping supplies on the drifting ice.
- McChord also had large maintenance facilities for Air Technical Service Command during the war, serving served as a P-39 Aircobra modification center April 1944 – May 1945 for lend-lease aircraft being sent to Russia via the Alaska Territory.
- 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.
- McChord Field/McChord AFB (TCM) has 2 runways.
- The furthest airport from McChord Field/McChord AFB (TCM) is Tôlanaro Airport (FTU), which is located 10,803 miles (17,386 kilometers) away in Tôlanaro, Madagascar.
- The base was the location of the first of twenty-eight stations built by ADC as part of the permanent air defense radar network, and was the top-priority site for ADC radars.
- In addition to being known as "McChord Field/McChord AFB", another name for TCM is "Part of Air Mobility Command (AMC)".
- 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.
