Black Disk Caught By Tourist Over Argentina Mountains, Aug 2018, UFO Sighting News.
Date of sighting: Aug 25, 2018 Location of sighting: El Hornocal Jujuy, Argentina Source: MUFON #94500
This UFO was caught by accident when a woman was having her picture taken and later noticed the black disk in the background. The UFO is moving horizontal to the mountains and looks like its moving very fast since it does have a slight blur to it. The blur could also be due to the crafts alien propulsion system causing a distortion around the craft. The disk may have come from an underground base nearby. Often aliens chose to make bases 4-6 miles under volcanos and steep mountains where humans are less likely to travel. Scott C. Waring
