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

About this route:

A direct, nonstop flight between Diomede Heliport (FAA: DM2) (DIO), Diomede, Alaska, United States and Guangyuan Airport (GYS), Guangyuan, Sichuan, China would travel a Great Circle distance of 4,069 miles (or 6,549 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 Guangyuan 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 Guangyuan Airport. You'll see that it will travel the same route of the red line on this map!

Facts about Diomede Heliport (FAA: DM2) (DIO):

• 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.
• Little Diomede Island is located about 25 miles west from the mainland, in the middle of the Bering Strait.
• 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 school year 1953–1954 in Little Diomede Island was adapted to better serve the local needs.
• The closest airport to Diomede Heliport (FAA: DM2) (DIO) is Wales Airport (WAA), which is located 26 miles (42 kilometers) ESE of DIO.
• 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.
• An electric system was built on the island in the 1970s and electricity is provided by city-operated Diomede Joint Utilities.

Facts about Guangyuan Airport (GYS):

• In addition to being known as "Guangyuan Airport", other names for GYS include "广元机场" and "Guǎngyuán Jīchǎng".
• The closest airport to Guangyuan Airport (GYS) is Mianyang Nanjiao Airport (MIG), which is located 87 miles (140 kilometers) SW of GYS.
• The furthest airport from Guangyuan Airport (GYS) is Viña del Mar Airport (KNA), which is nearly antipodal to Guangyuan Airport (meaning Guangyuan Airport is almost on the exact opposite side of the Earth from Viña del Mar Airport), and is located 12,268 miles (19,744 kilometers) away in Viña del Mar, Chile.
• Because of Guangyuan Airport's high elevation of 14,472 feet, planes must typically fly at a faster airspeed in order to takeoff or land at GYS. Combined with a high temperature, this could make GYS a "Hot & High" airport, where the air density is lower than it would otherwise be at sea level.
