Nonstop flight route between Washington, D.C. / Virginia, United States and Hyder, Alaska, United States:

About this route:

A direct, nonstop flight between Washington Dulles International Airport (IAD), Washington, D.C. / Virginia, United States and Hyder Seaplane Base (WHD), Hyder, Alaska, United States would travel a Great Circle distance of 2,641 miles (or 4,250 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 Washington Dulles International 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 Washington Dulles International Airport and Hyder Seaplane Base. You'll see that it will travel the same route of the red line on this map!

Facts about Washington Dulles International Airport (IAD):

• By the 1980s, the original design, which had mobile lounges meet each plane, was no longer well-suited to Dulles' role as a hub airport.
• The Metropolitan Washington Airports Authority has begun to gradually phase out the mobile lounge system for inter-terminal passenger movements in favor of the AeroTrain, an underground people mover which currently operates to Concourses A, B and C, and a pedestrian walkway system.

• Because of Washington Dulles International Airport's relatively low elevation of 313 feet, planes can take off or land at Washington Dulles International 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.
