AUTEC, the Caribbean
AUTEC (officially known as the Atlantic Underwater Testing & Evaluation Center) is what many UFO researchers call the U.S. Navy's version of Area 51. Not only have many UFOs been reported in its vicinity over the years, but hundreds of USOs (Unidentified Submerged Objects) have been seen near this super-secret facility as well. (The Navy denies all this, of course.) Maybe the eeriest thing about AUTEC is that it's located on the Bahamian island of Andros, which puts it smack in the middle of the Bermuda Triangle.
