I'm a round earther, so I don't believe the earth is flat, BUT
You are taking an image from a website that is run by people who believe in a round earth, and they made the image, so they aren't going to put in/leave in any thing that isn't there/contradicts what they are there to do, which is to demonstrate the shape of the earth/fool all of us. Footage that would apply to your statement would be flying from the tip of S. America in a plane and flying over Antartica.
