Date of sighting: October 30, 2015
Location of sighting: Mount Etna, Sicily, Italy
Here is a fantastic heat vision video by UFOvni2012 of Youtube. It shows a UFO entering the volcano in Italy. Volcanos were once the most inaccessible areas for humans, so aliens chose this area for their entrance/exits, but only some volcanos are used this way.
