Sydney-Santiago Flight Route

The Sydney-Santiago flight route is one of the southernmost passenger flights. Such a route is impossible if Earth were flat and confirms that Earth is a sphere. It is easy to verify the existence of this route from flight websites.

On a flat Earth, this route should go across the United States. But the duration of the Sydney-Santiago route with a stop in the US is much longer than the non-stop route because Earth is a sphere, and this route does not go anywhere near the United States.

Singapore–New York and Melbourne–Santiago Flight Routes

As of 2020, the Singapore–New York flight route is the world’s longest flight route, while the Melbourne–Santiago route is the most southernmost route. The real-world durations of these routes are only consistent if Earth is a sphere.

On the flat-Earth model, the Melbourne–Santiago flight route should be a longer flight than the Singapore–New York route. These routes’ real-world durations disprove the flat-Earth model.

Sydney-Johannesburg Flight Route

The existence of the non-stop Sydney-Johannesburg flight route is only possible if Earth is a sphere. We can find that out by comparing its duration to the same route but with a stop.

There are other Sydney-Johannesburg flight routes, but with a stop, like in Dubai. Flat-Earthers use the existence of these routes to “prove” a flat Earth. In reality, it does not mean the non-stop route does not exist & it is not difficult to verify that the non-stop route exists.

The Polar Azimuthal Equidistant Map is NOT the Flat Earth Map

The azimuthal equidistant map is a valid map. The map is a projection of the spherical Earth. Like every other map, it has distortions. It is not the “flat-Earth map,” and the usage of the azimuthal equidistant map does not endorse a flat Earth.

Flat-Earthers claim the shape of the polar azimuthal equidistant map as their own “flat-Earth map.” It is identical with the azimuthal equidistant map only in shape, but not in everything else. Unlike the azimuthal equidistant map, the so-called “flat-Earth map” does not represent reality.

The Taiwan–Los Angeles Flight (not from Bali) that was Diverted to Anchorage

There was a flight from Taiwan to Los Angeles that was diverted to Anchorage because one of the passengers gave birth to a baby. Flat-Earthers use the case as one of the first “evidence” from flight routes proving Earth is flat.

They are wrong. The case only tells us about the ignorance of these flat-Earthers about the distortion in a map projection. Their argument started with an elementary mistake of taking a straight line on a Mercator map between Taiwan and Los Angeles, and assume it as the “intended flight path.”

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.
