Nonstop flight route between Bonthe, Sierra Leone and Dum Dum (near Kolkata), India:

About this route:

A direct, nonstop flight between Sherbro International Airport (BTE), Bonthe, Sierra Leone and Netaji Subhas Chandra Bose International Airport (CCU), Dum Dum (near Kolkata), India would travel a Great Circle distance of 6,709 miles (or 10,797 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 Sherbro International Airport and Netaji Subhas Chandra Bose 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 Sherbro International Airport and Netaji Subhas Chandra Bose International Airport. You'll see that it will travel the same route of the red line on this map!

Facts about Sherbro International Airport (BTE):

• Because of Sherbro International Airport's relatively low elevation of 14 feet, planes can take off or land at Sherbro 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.
• The closest airport to Sherbro International Airport (BTE) is Gbangbatok Airport (GBK), which is located 22 miles (35 kilometers) NNE of BTE.
• The furthest airport from Sherbro International Airport (BTE) is Ulawa Airport (RNA), which is nearly antipodal to Sherbro International Airport (meaning Sherbro International Airport is almost on the exact opposite side of the Earth from Ulawa Airport), and is located 12,028 miles (19,357 kilometers) away in Arona, Ulawa Island, Solomon Islands.
