Nonstop flight route between Salmon, Idaho, United States and Tacoma, Washington, United States:

About this route:

A direct, nonstop flight between Lemhi County Airport (SMN), Salmon, Idaho, United States and McChord Field/McChord AFB (TCM), Tacoma, Washington, United States would travel a Great Circle distance of 434 miles (or 699 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 Lemhi County Airport and McChord Field/McChord AFB, the route shown on this map most likely still appears to be a straight line.

Facts about Lemhi County Airport (SMN):

• Because of Lemhi County Airport's high elevation of 4,043 feet, planes must typically fly at a faster airspeed in order to takeoff or land at SMN. Combined with a high temperature, this could make SMN a "Hot & High" airport, where the air density is lower than it would otherwise be at sea level.
• The furthest airport from Lemhi County Airport (SMN) is Tôlanaro Airport (FTU), which is located 10,686 miles (17,197 kilometers) away in Tôlanaro, Madagascar.
• Lemhi County Airport (SMN) currently has only 1 runway.
• The closest airport to Lemhi County Airport (SMN) is Challis Airport (CHL), which is located 45 miles (72 kilometers) SSW of SMN.

Facts about McChord Field/McChord AFB (TCM):

• 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.

• In 1917, the citizens of Pierce County, Washington approved a bond measure for $2,000,000 to buy 70,000 acres of land to be donated to the Federal Government for use as a military reservation.
• 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.
• In addition to being known as "McChord Field/McChord AFB", another name for TCM is "Part of Air Mobility Command (AMC)".
• McChord Field/McChord AFB (TCM) has 2 runways.
