About this route:
A direct, nonstop flight between Hamadan Airport (HDM), Hamadan, Iran and Washington Dulles International Airport (IAD), Washington, D.C. / Virginia, United States would travel a Great Circle distance of 6,281 miles (or 10,108 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 Hamadan Airport and Washington Dulles International 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 Hamadan Airport and Washington Dulles International Airport. You'll see that it will travel the same route of the red line on this map!

Facts about Hamadan Airport (HDM):
- Because of Hamadan Airport's high elevation of 5,755 feet, planes must typically fly at a faster airspeed in order to takeoff or land at HDM. Combined with a high temperature, this could make HDM a "Hot & High" airport, where the air density is lower than it would otherwise be at sea level.
- The furthest airport from Hamadan Airport (HDM) is Totegegie Airport (GMR), which is located 11,597 miles (18,663 kilometers) away in Mangareva, Gambier Islands, French Polynesia.

Facts about Washington Dulles International Airport (IAD):
- Washington Dulles Airport is the busiest airport in the Washington metropolitan area, and second busiest airport in the larger Baltimore–Washington metropolitan area with over 22 million passengers a year.
- 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.
- Under the development plan, future phases would see the addition of several new midfield concourses and a new south terminal.
- Dulles is accessible via the Dulles Access Road/Dulles Greenway and State Route 28.
- In September 2009, a 121,700 square feet central Transportation Security Administration checkpoint was added on a new security mezzanine level of the main terminal.
- Conceived in early planning sessions in 1959, Dulles is one of the few remaining airports to use the mobile lounge for boarding and disembarkation from aircraft, and to transfer passengers between the midfield concourses and to and from the main terminal building.
- The furthest airport from Washington Dulles International Airport (IAD) is Margaret River Airport (MGV), which is located 11,659 miles (18,763 kilometers) away in Margaret River, Western Australia, Australia.
