Mike, you bring up good points, however I find the reactions of the observers plausible. The shout seems due to the flashes, which would be visible to the naked eye. It is not surprising the witnesses are startled.
Also, there is a very interesting detail at ~0:48 sec, near the end of the video. Note the thundering sound. It occurs about 0.5-1.0 sec after the brightest flashes. Very roughly, this corresponds to a distance of 170-340 m from the camera.This seems a little close, but I'm guess-timating the time delay.
Regarding tourists and other witnesses, I don't know; there may indeed be other pictures/videos out there.
As for that very strange 'close up of UFO' video Eligael released; remember, he never claimed any association with it. Purportedly, it was given to him anonymously. I find Eligael's initial hesitation in releasing the full video a plausible reaction on his part too. From his statements, he seems pretty freaked out by this whole experience. IMHO the 'UFO' in the video is almost definitely CGI, and that 'monk' is laughable. I think that video should simply be discarded from the data set, along with the other fakes.
Also, don't forget the 'Brazil UFO' daytime video from a little while back, depicting very similar elements and behaviour of the UFO involved. Similar flashes.
Like I've mentioned before, taken together, all of this requires, literally, a worldwide conspiracy to be hoaxed. As well, in my opinion, some very sophisticated CGI effects that are as good as, or better than, feature movie quality.
