Nonstop flight route between Thanh Hoa, Vietnam and Saint Petersburg, Russia (formerly Leningrad between 1924 and 1991):

About this route:

A direct, nonstop flight between Tho Xuan Airport (THD), Thanh Hoa, Vietnam and Pulkovo Airport (LED), Saint Petersburg, Russia (formerly Leningrad between 1924 and 1991) would travel a Great Circle distance of 4,524 miles (or 7,281 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 Tho Xuan Airport and Pulkovo 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 Tho Xuan Airport and Pulkovo Airport. You'll see that it will travel the same route of the red line on this map!
