This one is very interesting... something silvery traveling at too high a rate of speed (one would think) for it to be anything but an Orb/UFO. Obviously in 2018... a drone will be mentioned as will "the perspective" between the object and the camera lens. But....I don't see any flapping of wings for the bird idea...and it looks like dozens of similar objects caught on video over the years...including live TV video. The original had over 400,000 views with about a 6-1 positive to negative public reaction. IF you read spanish...this is where the comments are Oct 2018 Argentina UFO On Live TV - this is the source video and is about 3 minutes long. This video, below, is an edited version of the longer TV newscast, and, will be the first of a number of videos that I've bookmarked recently... enjoy. 2018 UFO Video
