Nonstop flight route between Bangkok, Thailand and Cahokia, Illinois (near St. Louis), United States:

About this route:

A direct, nonstop flight between Suvarnabhumi Airport (BKK), Bangkok, Thailand and St. Louis Downtown Airport (CPS), Cahokia, Illinois (near St. Louis), United States would travel a Great Circle distance of 8,758 miles (or 14,094 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 Suvarnabhumi Airport and St. Louis Downtown 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 Suvarnabhumi Airport and St. Louis Downtown Airport. You'll see that it will travel the same route of the red line on this map!

Facts about Suvarnabhumi Airport (BKK):

• Further investigations found that taxilane and taxiway rutting was caused by separation of the asphalt binder from the aggregate surface due to prolonged water infiltration into the asphalt concrete base course, a phenomenon known as "stripping." The 23-centimetre thick base course is the top-most layer of the tarmac.
• The 8,400 acres plot of land occupied by the airport was purchased in 1973, but the student-led protests on 14 October that year led the overthrow of the military government of Prime Minister Thanom Kittikachorn and the project was shelved.
• Because of Suvarnabhumi Airport's relatively low elevation of 5 feet, planes can take off or land at Suvarnabhumi 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.
