This UFO Documentary looks at Underwater UFOs (better known as Unidentified Submerged Objects or USOs) at Santa Catalina Island (a supposed USO hot bed). What’s the difference between an unidentified submerged object and an unidentified flying object? There are two answers. One: The difference between a USO and a UFO is obviously that one is documented as maneuvering through the air, and the other through the water.

The second answer is: None. Most prominent UFO researchers believe the alien ships capable of flying around in our atmosphere, and even off into outer space, are the same ones that are reported underwater.
