Underwater UFO Sightings (USOs) From Atlantis to Modern Day

A look at reports of Underwater UFOs (USOs) "Unidentified Submerged Objects", throughout history -- from the ancient legends of Atlantis, to the reports of Christopher Columbus, to modern sightings around Laguna Cartagena, Puerto Rico (a supposed USO hot bed).

"What secrets lurk in ocean depths? Are there alien forms of intelligent life that occupy the vast volumes of water that constitute our oceans, seas, and lakes? The largest of our oceans, the Pacific, covers 64,000,000 square miles and reaches a depth of 36,198 feet, a depth that no ray of sunlight ever reaches. Could these depths hide alien submarine bases?




Underwater UFOs have been sighted on many occasions lifting out of their submerged depths and taking to the air. In an article entitled "UFOs - at 450 Fathoms," UFO Reporter Ed Hyde told of the sighting made by Dr. R. J. Villela, a Brazilian scientist, who saw a UFO smash through an estimated 40 feet of ice at the South Pole and soar into the sky at amazing speed.

It was author and researcher Dr. Ivan T. Sanderson who suggested that aliens could remain undetected by building their bases beneath the world's oceans. Dr. Sanderson found that by actual count, over 50 percent of the UFO sightings had occurred over, coming from, or plunging into or coming out of water. This includes oceans, seas, lakes, and reservoirs. Of the oceanic UFOs (some term them USOs or Unidentified Submersible Objects), one was tracked by the U.S. Navy near Puerto Rico in 1963. Of course many of these objects have been tracked over Puerto Rico since that time. On a training maneuver, a sonar operator detected a sub aqueous object traveling at over 150 knots! The technicians tracked this object for four days and it maneuvered down to the incredible depth of 27,000 feet. Submarines of 1963 could not dive further than a fraction over a mile into the ocean deeps. What kind of submersible could withstand the tremendous ocean pressures? And how could it overcome the tremendous resistance of water moving at such incredible speeds?
