About this route:
A direct, nonstop flight between Waco Regional Airport (ACT), Waco, Texas, United States and Lemhi County Airport (SMN), Salmon, Idaho, United States would travel a Great Circle distance of 1,293 miles (or 2,081 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 Waco Regional Airport and Lemhi County Airport, the route shown on this map most likely still appears to be a straight line.

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 "Waco Regional Airport", another name for ACT is "Blackland AAF".
- The airport was built by the United States Army Air Force as a pilot training airfield, and was activated on 2 July 1942.
