There are many non-stop, long-haul flight routes between different continents in the southern hemisphere, without crossing the northern hemisphere. These routes are only possible if Earth is a sphere, and impossible if Earth is flat.
Flat-Earthers claim that all long-haul flights south of the Equator always do a stop north of the Equator. In reality, there are plenty of non-stop routes between these locations, showing that Earth is a sphere.

In early October 2021, Qantas flew a one-off repatriation flight from Buenos Aires, Argentina, to Darwin, Australia. It was the southernmost long-haul flight closer to the South Pole than any other passenger flight.
If Earth were flat, the flight should fly over South America, Canada, Russia, Japan, and Indonesia. But it flew over Antarctica instead, because the Earth is a sphere, not flat.

Flight durations are a useful proxy for the distances between cities and easily debunk flat Earth. Flat-Earthers invented the “explanations” that the discrepancies of the flight durations in the flat Earth model are caused by winds and jet streams.
In reality, the required wind speed in such a scenario far exceeds the typical jet stream speed. Furthermore, the wind does not affect similar routes the same way in the flat Earth model. And we can easily account for the wind speed differences by averaging the flight durations in both directions. Continue reading “Wind & Jet Stream Excuses”
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.

The second voyage of James Cook was commissioned to search for the hypothetical continent Terra Australis in the Southern Pacific Ocean. He explored the Pacific and Atlantic oceans in the process and proved there is no such continent unless it is over the South Pole itself, which we now call Antarctica.
Some sources stated that Cook traveled over 60000 miles in his second voyage. Flat-Earthers use the figure as Antarctica’s circumference and claim it as “evidence” that Antarctica is much more than a continent. In reality, James Cook explored the vast ocean and did much more than just circumnavigating Antarctica.

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 majority of the flat Earth models place the Arctic Ocean in the middle of the flat Earth, and Antarctica at the edge of it. The Sun is pictured floating and moving in a circle above it. The Sun’s area of light is limited to a circular area below it, like a spotlight.
A problem: a simple observation of day and night cycles in a different area of the world cannot be explained in this flat Earth model.
