This event took place back in 1975 I was inside my house and somebody in the patio was screaming I went to see what the trouble was and the person started it pointing me out to the sky, I raised my head up and there it was a huge saucer with red lights around the edge and center bottom suspended in the air, didn't make any noise. The metal part was a gray mate color. I climbed to a mango tree and got up in the roof of the house, I laid down facing up an expecting something to happen but never did nor was afraid to have it real close enough to see details of the UFO, after about a minute that I was looking at, flown away so fast at speed that goes beyond my imagination. Recently, about two month ago I found two other people that saw the same event; we recreated the experience from that day. There were a lot of people they said, who witness the UFO. There was at least 4 witness.
