This is the route they took:

As you can clearly see it goes north and south. It goes down the west coast of South America across the suth pole and up the east coast of Africa.

Let's see how that looks on a flat earth

Huh. It looks like the plane disappears past South America and reappears some 20,000 miles away south of Madagascar. How did the plane travel all those miles in just a couple of hours?

Also the route on the flat earth map is like 20,000 more miles in length. How did that happen in the time it took? Did the plane travel faster than its top speed the whole way?
