Nonstop flight route between Shanghai, China and Salmon, Idaho, United States:

About this route:

A direct, nonstop flight between Shanghai Hongqiao International Airport (SHA), Shanghai, China and Lemhi County Airport (SMN), Salmon, Idaho, United States would travel a Great Circle distance of 6,128 miles (or 9,862 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 Shanghai Hongqiao International Airport and Lemhi County 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 Shanghai Hongqiao International Airport and Lemhi County Airport. You'll see that it will travel the same route of the red line on this map!

Facts about Shanghai Hongqiao International Airport (SHA):

• In addition to being known as "Shanghai Hongqiao International Airport", other names for SHA include "上海虹桥国际机场" and "Shànghǎi Hóngqiáo Guójì Jīchǎng".
• An airport was first built in the town of Hongqiao in the west of Shanghai in 1907, initially as a small military airfield.
• The closest airport to Shanghai Hongqiao International Airport (SHA) is Shanghai Pudong International Airport (PVG), which is located 28 miles (45 kilometers) E of SHA.
• The furthest airport from Shanghai Hongqiao International Airport (SHA) is Comodoro Pierrestegui Airport (COC), which is nearly antipodal to Shanghai Hongqiao International Airport (meaning Shanghai Hongqiao International Airport is almost on the exact opposite side of the Earth from Comodoro Pierrestegui Airport), and is located 12,397 miles (19,951 kilometers) away in Concordia, Entre Ríos, Argentina.
• Because of Shanghai Hongqiao International Airport's relatively low elevation of 10 feet, planes can take off or land at Shanghai Hongqiao 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.
• Shanghai Hongqiao International Airport handled 33,851,200 passengers last year.
• The proposed extension of the Shanghai Maglev Train from Longyang Road through Shanghai South Railway Station to Hongqiao would connect the two airports.
• Shanghai Hongqiao International Airport (SHA) has 2 runways.

• The furthest airport from Lemhi County Airport (SMN) is Tôlanaro Airport (FTU), which is located 10,686 miles (17,197 kilometers) away in Tôlanaro, Madagascar.
• Because of Lemhi County Airport's high elevation of 4,043 feet, planes must typically fly at a faster airspeed in order to takeoff or land at SMN. Combined with a high temperature, this could make SMN a "Hot & High" airport, where the air density is lower than it would otherwise be at sea level.
