On the evening of March 11, 2017, a spiral UFO flew out of the side opening of the Mexican volcano Popocatepetl (see video below).
A little below the smoking crater at 19:15 a bright white object appeared, which in just a few seconds reached a very significant speed and, stretched out in a long spiral, flew out of the range of the surveillance camera operating in live mode.
The video was posted on his channel by ufologist Marty Salas, who takes part in daily monitoring at the foot of Mexico's most active volcano, which is famous for its extraterrestrial alien activity.
As you can see, the UFO did not appear from the crater itself, but from a side vent located just below and to the right of the crater. Such holes serve as a kind of valves to relieve excess pressure in volcanoes. And, it is likely that the flow of volcanic gases escaping from the holes is a kind of elevator for alien objects rising to the surface.
Scientists and ufologists who organized daily and nightly observation of the volcano are sure of the existence of an alien base located deep under the volcano.
