Cerro San Cristóbal (Tupahue, San Cristóbal Hill) is a large viewpoint in northern Santiago, Chile. It rises 850 m AMSL and about 300 meters above the rest of Santiago; the peak is the second highest point in the city, after Cerro Renca. From this incredible vantage point over looking the city a tourist unsuspectingly filmed a UFO, which appears to fly at incredible velocity while making erratic aerial maneuvers and covering a large distance in seconds. Upon analyse the UFO Video footage in more detail I don’t believe this UFO to be any know aircraft or drone in use today. I have also enlarged and enhanced frames from the original source footage which shows in more detail the unusual shaped UFO.
