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

About this route:

A direct, nonstop flight between Diomede Heliport (FAA: DM2) (DIO), Diomede, Alaska, United States and Shanghai Hongqiao International Airport (SHA), Shanghai, China would travel a Great Circle distance of 3,700 miles (or 5,955 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 Shanghai Hongqiao 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 Diomede Heliport (FAA: DM2) and Shanghai Hongqiao International Airport. You'll see that it will travel the same route of the red line on this map!

• After the Cold War ended in the early 1990s, an interest of reuniting with families across the Bering Strait revived.
• Frozen ground and lack of soil on the rocky island also prevents digging graves, but rocks are piled on top of the burial sites instead.
• 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 closest airport to Diomede Heliport (FAA: DM2) (DIO) is Wales Airport (WAA), which is located 26 miles (42 kilometers) ESE of DIO.
