7.Star Ariel

6.USS Cyclops

During World War I, the USS Cyclops, commanded by Lt. G. W. Worley, carried coal for the U.S. Navy and 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." This tragedy stands as the single largest loss of life in U.S. Naval history not involving combat.

5.Flight 201

This Cessna left Fort Lauderdale, Fla. on March 31, 1984, en route for Bimini Island in the Bahamas, but it never made it. The passengers were all Cessna employees, including the pilot and co-pilots. Despite the experience of the crew, something went wrong. Not quite midway to its destination, the plane slowed its airspeed significantly, but no radio signals were made from the plane to indicate distress. Suddenly, the plane dropped from the air into the water, completely vanishing from the radar. A woman on Bimini Island reported seeing a plane plunge into the sea about a mile (1.61 kilometers) offshore, but no wreckage has ever been found.

4.Piper Navajo

On November 3, 1978, Irving Rivers left St. Croix (part of the U.S. Virgin Islands) in a Piper Navajo he was piloting for Eastern Caribbean Airways. The experienced pilot was making a solo flight to position the plane in St. Thomas to pick up passengers. Visibility was good and temperatures were warm. During the flight, the control tower operator radioed a flight suggestion to avoid a small shower, and Rivers radioed his acknowledgment and made the adjustment. As he neared the airport in St. Thomas, the plane was cleared for landing and the controller saw the plane's red and green lights blinking as it made the approach. Soon after another plane made a planned departure, the controller found he could no longer see the plane's lights -- it had disappeared from the radar. An emergency search effort was launched, but nothing was ever found -- even though the flight was only one mile (1.61 kilometers) from landing.
