Another Five unexplained mysteries.

6. The Bermuda Triangle

The Bermuda Triangle — located in the Atlantic between Bermuda , Florida and Puerto Rico — is a thief, stealing planes and boats right out of existence. The area got its name after Sgt. Howell Thompson (l.), along with 27 Navy airmen, vanished from the devilish spot during a routine flight in 1945. Rumors persist on a supernatural explanation, but many specialists blame hurricanes, a heavy Gulf Stream and human error.

7. The Nazca Lines

The Nazca Lines cover more than 190 square miles in the southern deserts of Peru . The mysterious shapes etched into the land rival football fields and predate the Incan Empire. The ‘Las Manos’ figure (above) is 2,000 years old. Little is know about why the Nazca people constructed such vast pieces of sand art, some believe they are extraterrestrial in nature, while others claim they may have carried and pointed to sources of water.

8. Aliens

Area 51, located on Groom Lake in southern Nevada (c.), was founded in 1955 by the U.S. Air Force to develop and test new aircrafts – such as the U-2 Spy Plane, A-12 Blackbird and F-117 Stealth Fighter. The secretive nature of the military base, combined with its classified aircraft research, helped conspiracy theorists imagine an installation filled with time-travel experimentation, UFO coverups and alien autopsies

9. Sphinx of Giza , Egypt

Another Egyptian wonder, the Sphinx of Giza has the body of a lion and the head of a Pharaoh, believed by most to be that of king Khafre. It was carved from soft limestone, and has been slowly falling apart over the years. A popular theory of the missing nose claims Napoleon’s soldiers shot it off with a cannon in 1798, but early sketches discovered of the Sphinx without a nose predate Napoleon’s rampage.

10. The Loch Ness Monster

According to Scottish folklore, a mystical creature called a water horse lures small children to a watery grave by tricking them to ride on its sticky back. The Loch Ness Monster became an English wonder in 1933, after witness accounts made newspaper headlines. No hard evidence of the creature has ever been recorded with several pictures, including the one above, being proven as hoaxes.
