Nonstop flight route between London, England, United Kingdom and Hyder, Alaska, United States:

About this route:

A direct, nonstop flight between London Heathrow Airport (LHR), London, England, United Kingdom and Hyder Seaplane Base (WHD), Hyder, Alaska, United States would travel a Great Circle distance of 4,478 miles (or 7,207 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 London Heathrow Airport and Hyder Seaplane Base, 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 London Heathrow Airport and Hyder Seaplane Base. You'll see that it will travel the same route of the red line on this map!

This is because the air density is higher closer to sea level than it would otherwise be at higher elevations.
• A trial of "noise relief zones" ran from December 2012 to March 2013, which concentrated approach flight paths into defined areas compared with the existing paths which were spread out.
• Full body scanners are now used at the airport, and passengers who object to their use after being selected are not allowed to fly.
