About this route:
A direct, nonstop flight between Alert Airport (YLT), Alert, Nunavut, Canada and Marfa Municipal Airport (MRF), Marfa, Texas, United States would travel a Great Circle distance of 3,744 miles (or 6,025 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 Alert Airport and Marfa Municipal 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 Alert Airport and Marfa Municipal Airport. You'll see that it will travel the same route of the red line on this map!

Facts about Alert Airport (YLT):
- There have been two crashes involving fatalities at the airfield since it was established.
- The furthest airport from Alert Airport (YLT) is Teniente Rodolfo Marsh Airport (TNM), which is located 9,999 miles (16,092 kilometers) away in Villa Las Estrellas, Antarctica.
- Because of Alert Airport's relatively low elevation of 100 feet, planes can take off or land at Alert 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.
- A weather station was established on the site in 1950, and in 1957 construction began on the military facilities which are still in use to this day.
- The closest airport to Alert Airport (YLT) is Eureka Aerodrome (YEU), which is located 299 miles (481 kilometers) WSW of YLT.

- The closest airport to Marfa Municipal Airport (MRF) is Alpine-Casparis Municipal Airport (ALE), which is located only 20 miles (32 kilometers) E of MRF.
- Because of Marfa Municipal Airport's high elevation of 4,849 feet, planes must typically fly at a faster airspeed in order to takeoff or land at MRF. Combined with a high temperature, this could make MRF a "Hot & High" airport, where the air density is lower than it would otherwise be at sea level.
