A March 1st UFO sighting over Siberia tied to underwater alien base, "some locals blamed the event on a alien UFO base said to exist beneath Lake Baikal." Tangible facts are hard to come by, but circles in the thin ice of Lake Baikal (picture) are puzzling . Thermal activity and convection believed responsible for warm water columns that rise to melt surface ice. An article at the Earth Observatory page on NASA website, however, finds circle at south end of lake in relatively deep water a challenge to this belief.
In "UFO Encounters Of Russian Navy Released," the article reports in 1982 case, "a group of military divers training at Baikal spotted a group of humanoid creatures dressed in silvery suits. The encounter happened at a depth of 50 meters, and the divers tried to catch the strangers. Three of the seven men died, while four others were severely injured." In the March 1st sighting, first article also revealed, "only hours prior to this event, air-traffic controllers in Yakutks, Siberia claim to have picked up a UFO on radar traveling at 6000 mph at a height of 65000. When they tried to speak with the crew of that craft they heard bizarre cat noises being uttered to them."
Thousands of local Irkutsk residents witnessed a huge object, glowing pink and blue, hurtle towards earth, followed by a loud explosion heard over a wide area. Russian officials declared crash site classified and would not reveal location.
