This is unlikely to be faked, and it is moving far too quickly to be a small aircraft or a balloon. A genuine unknown.
nice, one really fast white spacecraft I guess. don't think we got those lol
The information that comes with this video on YouTube has been changed to the following...
"IMPORTANT UPDATE 04/08/2012: This video may be a fake. More detailed information (read information text): http://www.youtube.com/watch?v=rDxwbmYQgPo"
...my opinion is, (apart from the strange object that appears in the first seconds of the video, which the additional clip highlights (http://www.youtube.com/watch?v=rDxwbmYQgPo)) the audio suggests that whomever was filming it saw the object ("Did you see that?") but makes absolutely no attempt to follow the object.
Same old story. I don't think the UFO was in the original footage.
Fake = True.
