After reading these forums for a few hours I can safely say that video evidence will not disprove FET, because all pictures and/or videos can be faked. Even if a respected member of the forum was to post video footage of the earth from space which they took themselves it would be discounted as the government using their name to release more fake images.
I would like to see an example of a situation that would prove to a FE theorist that the earth is round. (Please don't say "you can't! it's flat!)
For instance, here is what would prove the earth is flat:
Legitimate news agency films the ice wall. Hell, even a picture would do. CNN, CBS, ABC, NBC, BBC, NYTimes, Boston Globe, AP, Washington Post, Wall Street Journal, ect.
And now, a picture of a mountain won't do. I'd like to see the ocean hitting a wall of ice that's covering the horizon from one of these news agencies.
