Subterranean Bases and Flying Saucers

RecordOBS-0785
CategoryExtraterrestrial/UFOs
StatusUNPROVEN
SummarySome modern proponents of the Hollow Earth theory claim that flying saucers originate from inside the Earth, entering and exiting through polar openings or other hidden entrances. They also suggest that secret underground bases exist, possibly operated by governments or extraterrestrials.
OriginThis idea gained traction in the mid-20th century with the rise of UFO sightings and conspiracy theories about secret government projects.
Claimed
  • Flying saucers are based inside the Earth.
  • There are openings to the center of the Earth in the Alaska Range and other locations.
  • Governments hide the existence of these bases and the hollow Earth.
  • The hollow Earth is an entry and exit point for UFOs.
Evidence / consensusThere is no credible evidence for flying saucers originating from inside the Earth or for secret underground bases. UFO phenomena are not conclusively linked to any subterranean origin.
> OBSERVER NOTE:
A modern fusion of hollow Earth and UFO lore. No verifiable evidence supports the existence of subterranean UFO bases. The claims remain in the realm of speculation.
