Nonstop flight route between Diomede, Alaska, United States and Lanzhou, Gansu, China:

About this route:

A direct, nonstop flight between Diomede Heliport (FAA: DM2) (DIO), Diomede, Alaska, United States and Lanzhou Zhongchuan Airport (LHW), Lanzhou, Gansu, China would travel a Great Circle distance of 3,878 miles (or 6,241 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 Diomede Heliport (FAA: DM2) and Lanzhou Zhongchuan 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 Diomede Heliport (FAA: DM2) and Lanzhou Zhongchuan Airport. You'll see that it will travel the same route of the red line on this map!

• There is no hospital on the island and emergency services are limited due to the remoteness of the island.
• Water for winter use is drawn from a mountain spring, then treated and stored in 434,000-U.S.-gallon storage tanks.
• Because of Diomede Heliport (FAA: DM2)'s relatively low elevation of 0 feet, planes can take off or land at Diomede Heliport (FAA: DM2) 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 furthest airport from Diomede Heliport (FAA: DM2) (DIO) is Teniente Rodolfo Marsh Airport (TNM), which is located 10,411 miles (16,755 kilometers) away in Villa Las Estrellas, Antarctica.
