Pretty interesting stuff. The first one I am calling shenanigans on it. Looks like something too much out of a movie. I think if that was real footage that it would have been all over the news but I don't recall ever once seeing it until now. The second one I think might actually be real, so I don't have any more to say on it. The third one I am calling shenanigans on, too. I think is just a remote control toy that is zoomed in on to make it look bigger.
