This frame grab shows what appears to be a convincing UFO shot from a small plane over Japan. The video, however, has been made private on YouTube. Link to source for larger image.
It strikes me as rather mysterious that they have made the video "private." If it was a CGI fake they would want everyone to see it. That's the whole idea behind a hoax. Perhaps the owner(s) of the video has been offered money for the rights. Various scenarios come to mind. I'm more inclined to think that they've really captured something here on video, rather than it being a video hoax.
