bladeofBG: N/p. Most UFO vids on youtube are of better quality than my camera (wherein even if I spotted one, it'd be an insult to try and film'em!), so I'm not in a position to judge their quality as I'm not well-versed in anything better. I will say in defense of the videos, that I'm sure the original videos that users post are indeed longer, but they don't post those original videos b/c it'd be kind of pointless to share watching a UFO do nothing but fly w/zero interaction for more than 3-5 minutes.
I still think its intriguing, and thus thought I'd share it. :OD
Yeah, the main problems in those vids is that they "happened" in full daylight, at a time where almost ALL japanese people were anxiously watching TV news all day long in order to se what was happening. So I doubt that such a thing would have remained unnoticed, or that there is a conspiracy wide enough to hide that, especially in Japan.
