These ill-fated flights have fallen victim to the mysterious powers of the Bermuda Triangle. Find out how these planes were never heard from again.

3. USS Cyclops

As World War I heated up, America went to battle. The Cyclops, commanded by Lt. G. W. Worley, stayed mostly on the East Coast of the United States until 1918 when it was sent to Brazil to refuel Allied ships. With 309 people onboard, the ship left Rio de Janeiro in February and reached Barbados in March. After that, the Cyclops was never heard from again. The Navy says in its official statement, "The disappearance of this ship has been one of the most baffling mysteries in the annals of the Navy, all attempts to locate her having proved unsuccessful. There were no enemy submarines in the western Atlantic at that time, and in December 1918 every effort was made to obtain from German sources information regarding the disappearance of the vessel."

4. Star Tiger

The Star Tiger, commanded by Capt. B. W. McMillan, was flying from England to Bermuda in January 1948. On January 30, McMillan said he expected to arrive in Bermuda at 5:00 a.m., but neither he nor any of the 31 people onboard the Star Tiger were ever heard from again. When the Civil Air Ministry launched a search and investigation, they learned that the S.S. Troubadour had reported seeing a low-flying aircraft halfway between Bermuda and the entrance to Delaware Bay. If that aircraft was the Star Tiger, it was drastically off course. According to the Civil Air Ministry, the fate of the Star Tiger remains an unsolved mystery.

5. Star Ariel

A Tudor IV aircraft like the Star Tiger left Bermuda on January 17, 1949, with 7 crew members and 13 passengers en route to Jamaica. That morning, Capt. J. C. McPhee reported that the flight was going smoothly. Shortly afterward, another more cryptic message came from the captain, when he reported that he was changing his frequency, and then nothing more was heard, ever. More than 60 aircraft and 13,000 men were deployed to look for the Star Ariel, but not even a hint of debris or wreckage was ever found. After the Ariel disappeared, Tudor IVs were no longer produced.

6. The Spray

Joshua Slocum, the first man to sail solo around the world, never should have been lost at sea, but it appears that's exactly what happened. In 1909, the Spray left the East Coast of the United States for Venezuela via the Caribbean Sea. Slocum was never heard from or seen again and was declared dead in 1924. The ship was solid and Slocum was a pro, so nobody knows what happened. Perhaps he was felled by a larger ship or maybe he was taken down by pirates. No one knows for sure that Slocum disappeared within Triangle waters, but Bermuda buffs claim Slocum's story as part of the legacy of the Devil's Triangle.

7. Teignmouth Electron

Who said that the Bermuda Triangle only swallows up ships and planes? Who's to say it can't make a man go mad, too? Perhaps that's what happened on the Teignmouth Electron in 1969. The Sunday Times Golden Globe Race of 1968 left England on October 31 and required each contestant to sail his ship solo. Donald Crowhurst was one of the entrants, but he never made it to the finish line. The Electron was found abandoned in the middle of the Bermuda Triangle in July 1969. Logbooks recovered from the ship reveal that Crowhurst was deceiving organizers about his position in the race and going a little nutty out there in the big blue ocean. The last entry of his log was dated June 29 -- it is believed that Crowhurst jumped overboard and drowned himself in the Triangle.
