In the future, try to not create topics with no content other than a link.
Also, the picture looks exactly like what you would expect to see if you were high enough over a disk. So to answer your question, we think it's proof of a flat earth.
No it doesn't. You try this one with every single photo that shows earth curvature, and the flaw in your argument this time is that this was launched from
Wales.
Do you know where Wales is? If you're American, the answer will be no, but since everyone else probably does, I'll continue without further clarification. You would not be able to see a big rounded curve of the entire earth perimeter from Wales, especially at an altitude of 21 miles, if the disc of the earth is the diameter the FAQ claims it to be, as it would simply not be high enough to see it properly. Draw a diagram to scale if you don't believe me. Secondly, in order to claim the curve represents the edge of the disc and not the visible portion of a spheroid, you'd need to have more than one picture taken in different directions in order to assess if the edge was further away in one direction than in another, because unless you observe from over the centre of the disc (not Wales, for the Americans out there), there will be more curve one way than another. With a single image, you can't make that claim. Additionally, there have been high altitude images of this type in which the camera spins round a full 360 degrees and a curved edge is visible in every direction with
no area of darkness where the sun is not shining. Since the sun cannot illuminate the entire disc at once, that demonstrates your hypothesis to be wrong.
And finally, if the earth was flat, it would have straight edges not curved ones.
