I was watching a video on HULU: UFOTV presents UFO's in South America, 2010.Unique UFO's formation of 20 or more on separate occasions, the formation does not make sense unless they are conveying a message in the way they were arranging their flight. I am a professional pilot and the flight although not a loose formation had in my mind had a pictographic meaning, look at it.((NUFORC Note: Witness indicates that the date of the sighting is approximate. PD))
