## Antipodal Flight Route: Jakarta–Bogota

Jakarta & Bogota are a near antipodal pair: the opposite points on Earth’s surface. We can fly from Jakarta in any direction and arrive at Bogota after traveling a similar distance, irrespective of the direction we leave Jakarta.

Any flight between an antipodal pair has a similar duration even though the different flights have different directions. This fact is only consistent with spherical Earth and cannot possibly be explained if Earth is flat.

For example, on a flat Earth, the flight route of Jakarta–Hong Kong–New York–Bogota is almost a straight route between the two locations. Meanwhile, the Jakarta–Sydney–Auckland–Santiago–Bogota route involves a massive detour, and it should take much longer than the aforementioned straight route. However, contrary to what is expected in the flat Earth model, both routes have a similar flight duration.

## Flight Durations

• Jakarta–Istanbul–Bogota: 12h 0m + 13h 45m = 25.75 hours
• Jakarta–Hong Kong–New York–Bogota: 5h 5m + 16h 0m + 5h 42m = 26.783 hours
• Jakarta–Tokyo–Houston–Bogota: 7h 35m + 12h 5m + 4h 55m = 24.583 hours
• Jakarta–Sydney–Auckland–Santiago–Bogota: 6h 55m + 3h 5m + 11h 0m + 6h 14m = 27.23 hours

## Emergency Landings and Flight Route

We cannot take a straight line between two locations on a map and consider that line the shortest distance between the two locations. With a very short distance —like within a city— it wouldn’t usually matter. But for long-haul flights across continents, then it would matter a lot.

Flat-Earthers are known to use this mistake —whether deliberately or not— as a ‘proof’ that the Earth is flat. A common case they would bring is emergency landings.
