About this route:
A direct, nonstop flight between Plymouth City Airport (PLH), Plymouth, United Kingdom and Lemhi County Airport (SMN), Salmon, Idaho, United States would travel a Great Circle distance of 4,615 miles (or 7,427 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 Plymouth City Airport and Lemhi County 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 Plymouth City Airport and Lemhi County Airport. You'll see that it will travel the same route of the red line on this map!

- The closest airport to Plymouth City Airport (PLH) is Exeter International Airport (EXT), which is located 37 miles (60 kilometers) NE of PLH.
- An RAF Chinook was forced to make an emergency landing at Plymouth Airport on 25 Nov 2011.
- Because of Plymouth City Airport's relatively low elevation of 476 feet, planes can take off or land at Plymouth City 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.
- The airport was officially closed by the Sutton Harbour Group on 23 December 2011.
- Plymouth City Airport (PLH) currently has only 1 runway.
- Plymouth City Airport handled 157,933 passengers last year.
- A multimillion pound airport redevelopment was given the go ahead.
