USS Memphis in 1916, hard aground in the Dominican Republic after an encounter with a freak wave. (U.S. Navy)An explanation for some of the disappearances has focused on the presence of vast fields of methane hydrates on the continental shelves. Laboratory experiments carried out in Australia have proven that bubbles can, indeed, sink a scale model ship by decreasing the density of the water[10]; any wreckage consequently rising to the surface would be rapidly dispersed by the Gulf Stream. It has been hypothesized that periodic methane eruptions (sometimes called "mud volcanoes") may produce regions of frothy water that are no longer capable of providing adequate buoyancy for ships. If this were the case, such an area forming around a ship could cause it to sink very rapidly and without warning.

Airplanes may also be susceptible to any freak methane releases. Methane also has the ability to cause a piston engine to stall when released into the atmosphere, even at an atmospheric concentration as low as 1%[citation needed]. But although methane is lighter than air, the altimeter of an airplane traveling through it would not, contrary to popular belief, read that the airplane is higher than it really is, causing navigational problems. (Altimeters measure pressure, not the density of air.)

A white paper was published in 1981 by the United States Geological Survey about the appearance of hydrates in the Blake Ridge area, off the southeastern United States coast.[11] However, according to a USGS web page, no large releases of gas hydrates are believed to have occurred in the Bermuda Triangle for the past 15,000 years.[12]


Compass variations
Compass problems are one of the cited phrases in many Triangle incidents. The North Magnetic Pole is not the North Pole; rather it is the north end of the earth's magnetic field. The North Magnetic Pole does wander, but so slowly that the wandering would not be noticeable on time scale of a sea or air voyage. In general, the compass does not point exactly the direction of the North Magnetic Pole, but rather the compass needle aligns itself to the local geomagnetic field, which can vary in a complex manner over the Earth's surface, as well as over time.

The angular difference between magnetic north and true north (defined in reference to the Geographic North Pole), at any particular location on the Earth's surface, is called the magnetic declination. Most map coordinate systems are based on true north, and magnetic declination is often shown on map legends so that the direction of true north can be determined from north as indicated by a compass. The line of zero declination in the U.S. runs from the North Magnetic Pole through Lake Superior and across the western panhandle of Florida. Along this line, true north is the same as magnetic north. West of the line of zero declination, a compass will give a reading that is east of true north. Conversely, east of the line of zero declination, a compass reading will be west of true north. Since the North Magnetic Pole has been slowly migrating toward the northwest, some twenty or more years ago the line of zero declination went through the Triangle, giving sailors an alignment of true north with magnetic north.[13]

Some have theorized the possibility of unusual local magnetic anomalies in the area, however these have not been shown to exist.


Hurricanes
Hurricanes are extremely powerful storms which are spawned in the Atlantic near the equator, and have historically been responsible for thousands of lives lost and billions of dollars in damage. The sinking of Francisco de Bobadilla's Spanish fleet in 1502 was the first recorded instance of a destructive hurricane. In 1988, Hurricane Gilbert, one of the most powerful hurricanes in history, set back Jamaica's economy by three years. These storms have in the past caused a number of incidents related to the Triangle.


Gulf Stream
The Gulf Stream is an ocean current that originates in the Gulf of Mexico, and then through the Straits of Florida, into the North Atlantic. In essence, it is a river within an ocean, and like a river, it can and does carry floating objects. A small plane making a water landing or a boat having engine trouble will be carried away from its reported position by the current, as happened to the cabin cruiser Witchcraft on December 22, 1967, when it reported engine trouble near the Miami buoy marker one mile from shore, but was not there when a Coast Guard cutter arrived.


Freak waves
Main article: Rogue wave (oceanography)
Extremely large waves can appear seemingly at random, even in calm seas. One such rogue wave caused the Ocean Ranger to capsize in 1982, then the worlds largest offshore platform. There is, however, no particular reason to believe rogue waves are more common in the Bermuda region, and this could not explain loss of airplanes.

Answer 2

The scientific explanation is that nothing out of the ordinary goes on in the Bermuda triangle. It's a heavily-traveled piece of ocean that has its share of lost ships and planes. The popular conception of it as a place of danger and mystery is based on anecdotal evidence, often distorted to deepen the "mystery". Statistical analysis of the area shows it has no greater disaster rate than any similar region of the seas.

Answer 3

A few months ago , i have seen a 1 hour video from National Geographic about it.
The first incident happened in 1942 during WW2.
After that it has been continuous .
when some plane , or ship passes through this region, it looses its contacts.
The most exciting is the experiment done by NetGeo.
They simulated the flight of Flight 19 (5 planes of same model as used during 1942) and started at the same time .And u know exactly at the sae time as Flight 19 reported , this simultion rported the same problem.
Though there are lot many theory which try to unfold the mistery, but none of them are perfect.
To me it seems like the toughest challange to scintific world.
also i believe not all of these are co-incidence.Though the finding is encouraging.

Answer 4

No scientific explaination is yet availabe for d bermuda triangle in d world.

Answer 5

its a geographic phenomenon, not quite sure what its called but there is a spot exactly like the bermuda triangle in the pacific ocean, its just not as famous

Answer 6

i've heard some scientist say theat that it is a gravitational hotspot. meaning that there are clusters of magnetic forces condensed in that one particular area. which is unusual because normally they should be more spread out. but plane and boats and crap like that have disappeared through there, but from other peeple it's supposed to be a tear in the fabric of space and time, like a door through time. but you should go first hand out there and fly thorugh it and let the rest of us know what's in there.

Answer 7

i just read some articles about this and it states that "whenever there is a plane or ship crosses that particular area,it later vanishes.......and theres 1% possibility for the plane or ship to recover....".freaky weird.

Answer 8

The Bermuda Triangle, also known as the Devil's Triangle, is a region of the northwestern Atlantic Ocean in which a number of aircraft and surface vessels have disappeared in what are said to be circumstances that fall beyond the boundaries of human error or acts of nature. Some of these disappearances have been attributed to the paranormal, a suspension of the laws of physics, or activity by extraterrestrial beings by popular culture.[1] Although a substantial documentation exists showing numerous incidents to have been inaccurately reported or embellished by later authors, several others remain unexplained.

The Triangle area

The area of the Triangle varies by author.The boundaries of the Triangle vary with the author; some stating its shape is akin to a trapezium covering the Straits of Florida, the Bahamas, and the entire Caribbean island area east to the Azores; others add to it the Gulf of Mexico. The more familiar, triangular boundary in most written works has as its points Miami, Florida; San Juan, Puerto Rico; and the mid-Atlantic island of Bermuda, with most of the accidents concentrated along the southern boundary around the Bahamas and the Florida Straits.

The area is one of the most heavily-sailed shipping lanes in the world, with ships crossing through it daily for ports in the Americas and Europe, as well as the Caribbean Islands. Cruise ships are also plentiful, and pleasure craft regularly go back and forth between Florida and the islands. It is also a heavily flown route for commercial and private aircraft heading towards Florida, the Caribbean, and South America from points north.

The Gulf Stream ocean current flows through the Triangle after leaving the Gulf of Mexico; its current of five to six knots may have played a part in a number of disappearances. Sudden storms can and do appear, and in the summer to late fall the occasional hurricane strikes the area. The combination of heavy maritime traffic and tempestuous weather makes it inevitable that vessels could founder in storms and be lost without a trace — especially before improved telecommunications, radar, and satellite technology arrived late in the 20th century.[2]


History of the Triangle story
According to the Triangle authors, Christopher Columbus was the first person to document something strange in the Triangle, reporting that he and his crew observed "strange dancing lights on the horizon", flames in the sky, and at another point he wrote in his log about bizarre compass bearings in the area. From his log book, dated October 11, 1492 he wrote:

"The land was first seen by a sailor (Rodrigo de Triana), although the Admiral at ten o'clock that evening standing on the quarter-deck saw a light, but so small a body that he could not affirm it to be land; calling to Pero Gutiérrez, groom of the King's wardrobe, he told him he saw a light, and bid him look that way, which he did and saw it; he did the same to Rodrigo Sánchez of Segovia, whom the King and Queen had sent with the squadron as comptroller, but he was unable to see it from his situation. The Admiral again perceived it once or twice, appearing like the light of a wax candle moving up and down, which some thought an indication of land. But the Admiral held it for certain that land was near..."
Modern scholars checking the original log books have surmised that the lights he saw were the cooking fires of Taino natives in their canoes or on the beach; the compass problems were the result of a false reading based on the movement of a star. The flames in the sky were undoubtedly falling meteors, which are easily seen while at sea.[3]

The first article of any kind in which the legend of the Triangle began appeared in newspapers by E.V.W. Jones on September 16, 1950, through the Associated Press. Two years later, Fate magazine published "Sea Mystery At Our Back Door", a short article by George X. Sand in the October 1952 issue covering the loss of several planes and ships, including the loss of Flight 19, a group of five U.S. Navy TBM Avenger bombers on a training mission. Sand's article was the first to lay out the now-familiar triangular area where the losses took place. Flight 19 alone would be covered in the April 1962 issue of American Legion Magazine. The article was titled "The Lost Patrol", by Allen W. Eckert, and in his story it was claimed that the flight leader had been heard saying "We are entering white water, nothing seems right. We don't know where we are, the water is green, no white." It was also claimed that officials at the Navy board of inquiry stated that the planes "flew off to Mars." "The Lost Patrol" was the first to connect the supernatural to Flight 19, but it would take another author, Vincent Gaddis, writing in the February 1964 Argosy Magazine to take Flight 19 together with other mysterious disappearances and place it under the umbrella of a new catchy name: "The Deadly Bermuda Triangle";[4] he would build on that article with a more detailed book, Invisible Horizons, the next year. Others would follow with their own works: John Wallace Spencer (Limbo of the Lost, 1969); Charles Berlitz (The Bermuda Triangle, 1974); Richard Winer (The Devil's Triangle, 1974), and many others, all keeping to some of the same supernatural elements outlined by Eckert.[5]


Kusche's explanation
Lawrence David Kusche, a research librarian from Arizona State University and author of The Bermuda Triangle Mystery: Solved (1975) has challenged this trend. Kusche's research revealed a number of inaccuracies and inconsistencies between Berlitz's accounts and statements from eyewitnesses, participants, and others involved in the initial incidents. He noted cases where pertinent information went unreported, such as the disappearance of round-the-world yachtsman Donald Crowhurst, which Berlitz had presented as a mystery, despite clear evidence to the contrary. Another example was the ore-carrier Berlitz recounted as lost without trace three days out of an Atlantic port when it had been lost three days out of a port with the same name in the Pacific Ocean. Kusche also argued that a large percentage of the incidents which have sparked the Triangle's mysterious influence actually occurred well outside it. Often his research was surprisingly simple: he would go over period newspapers and see items like weather reports that were never mentioned in the stories.

Kusche came to several conclusions:

The number of ships and aircraft reported missing in the area was not significantly greater, proportionally speaking, than in any other part of the ocean.
In an area frequented by tropical storms, the number of disappearances that did occur were, for the most part, neither disproportionate, unlikely, nor mysterious; furthermore, Berlitz and other writers would often fail to mention such storms.
The numbers themselves had been exaggerated by sloppy research. A boat listed as missing would be reported, but its eventual (if belated) return to port may not be reported.
Some disappearances had in fact, never happened. One plane crash was said to have taken place in 1937 off Daytona Beach, Florida, in front of hundreds of witnesses; a check of the local papers revealed nothing.
Kusche concluded that:

"The Legend of the Bermuda Triangle is a manufactured mystery... perpetuated by writers who either purposely or unknowingly made use of misconceptions, faulty reasoning, and sensationalism." (Epilogue, p. 277)
In recent years, however, several authors, most notably Gian J. Quasar, have raised several questions as to the veracity of Kusche's findings, including, but not limited to, why Kusche so often brought up as evidence for his claims cases that were already well-known before the writing of his work as not being Triangle incidents; his misidentification and mislocation of several ship and aircraft incidents that are well-documented, but then using that inability to properly identify the craft as "proof" that they never existed; and in other examples openly claiming possibilities for foul weather for certain disappearances where it can be verified that none existed.[6]


Other responses
The marine insurer Lloyd's of London has determined the Triangle to be no more dangerous than any other area of ocean, and does not charge unusual rates for passage through the region. United States Coast Guard records confirm their conclusion. In fact, the number of supposed disappearances is relatively insignificant considering the number of ships and aircraft which pass through on a regular basis.

The Coast Guard is also officially skeptical of the Triangle, noting that they collect and publish, through their inquiries, much documentation[7] contradicting many of the incidents written about by the Triangle authors. In one such incident involving the 1972 explosion and sinking of the tanker V.A. Fogg in the Gulf of Mexico, the Coast Guard photographed the wreck and recovered several bodies[8] despite one Triangle author stating that all the bodies had vanished, with the exception of the captain, who was found sitting in his cabin at his desk, clutching a coffee cup (Limbo of the Lost by John Wallace Spencer, 1973 edition).

Skeptical researchers, such as Ernest Taves and Barry Singer, have noted how mysteries and the paranormal are very popular and profitable. This has led to the production of vast amounts of material on topics such as the Bermuda Triangle. They were able to show that some of the pro-paranormal material is often misleading or not accurate, but its producers continue to market it. They have therefore claimed that the market is biased in favour of books, TV specials, et cetera. which support the Triangle mystery and against well-researched material if it espouses a skeptical viewpoint.[9]

There is, however, no particular reason to believe rogue waves are more common in the Bermuda region, and this could not explain loss of airplanes.


Acts of Man

Human error
One of the most cited explanations in official inquiries as to the loss of any aircraft or vessel is human error. Whether deliberate or accidental, humans have been known to make mistakes resulting in catastrophe, and losses within the Bermuda Triangle are no exception. For example, the Coast Guard cited a lack of proper training for the cleaning of volatile benzene residue as a reason for the loss of the tanker V.A. Fogg in 1972. Human stubbornness may have caused businessman Harvey Conover to lose his sailing yacht, the Revonoc, as he sailed into the teeth of a storm south of Florida on January 1, 1958. It should be noted that many losses remain inconclusive due to the lack of wreckage which could be studied, a fact cited on many official reports.


Deliberate acts of destruction
This can fall into two categories: acts of war, and acts of piracy. Records in enemy files have been checked for numerous losses; while many sinkings have been attributed to surface raiders or submarines during the World Wars and documented in the various command log books, many others which have been suspected as falling in that category have not been proven; it is suspected that the loss of USS Cyclops in 1918, as well as her sister ships Proteus and Nereus in World War II, were attributed to submarines, but no such link has been found in the German records.

Piracy, as defined by the taking of a ship or small boat on the high seas, is an act which continues to this day. While piracy for cargo theft is more common in the western Pacific and Indian oceans, drug smugglers do steal pleasure boats for smuggling operations, and may have been involved in crew and yacht disappearances in the Caribbean. Historically famous pirates of the Caribbean (where piracy was common from about 1560 to the 1760s) include Edward Teach (Blackbeard) and Jean Lafitte. Lafitte is sometimes said to be a Triangle victim himself.

Another form of pirate operated on dry land. Bankers or wreckers would shine a light on shore to misdirect ships, which would then founder on the shore; the wreckers would then help themselves to the cargo. It is possible that these wreckers also killed any crew who protested. Nags Head, North Carolina, was named for the wreckers' practice of hanging a lantern on the head of a hobbled horse as it walked along the beach.

A small plane making a water landing or a boat having engine trouble will be carried away from its reported position by the current, as happened to the cabin cruiser Witchcraft on December 22, 1967, when it reported engine trouble near the Miami buoy marker one mile from shore, but was not there when a Coast Guard cutter arrived.


Freak waves
Main article: Rogue wave (oceanography)
Extremely large waves can appear seemingly at random, even in calm seas. One such rogue wave caused the Ocean Ranger to capsize in 1982, then the worlds largest offshore platform. There is, however, no particular reason to believe rogue waves are more common in the Bermuda region, and this could not explain loss of airplanes.


Acts of Man

Human error
One of the most cited explanations in official inquiries as to the loss of any aircraft or vessel is human error. Whether deliberate or accidental, humans have been known to make mistakes resulting in catastrophe, and losses within the Bermuda Triangle are no exception. For example, the Coast Guard cited a lack of proper training for the cleaning of volatile benzene residue as a reason for the loss of the tanker V.A. Fogg in 1972. Human stubbornness may have caused businessman Harvey Conover to lose his sailing yacht, the Revonoc, as he sailed into the teeth of a storm south of Florida on January 1, 1958. It should be noted that many losses remain inconclusive due to the lack of wreckage which could be studied, a fact cited on many official reports.


Deliberate acts of destruction
This can fall into two categories: acts of war, and acts of piracy. Records in enemy files have been checked for numerous losses; while many sinkings have been attributed to surface raiders or submarines during the World Wars and documented in the various command log books, many others which have been suspected as falling in that category have not been proven; it is suspected that the loss of USS Cyclops in 1918, as well as her sister ships Proteus and Nereus in World War II, were attributed to submarines, but no such link has been found in the German records.

Piracy, as defined by the taking of a ship or small boat on the high seas, is an act which continues to this day. While piracy for cargo theft is more common in the western Pacific and Indian oceans, drug smugglers do steal pleasure boats for smuggling operations, and may have been involved in crew and yacht disappearances in the Caribbean. Historically famous pirates of the Caribbean (where piracy was common from about 1560 to the 1760s) include Edward Teach (Blackbeard) and Jean Lafitte. Lafitte is sometimes said to be a Triangle victim himself.

Another form of pirate operated on dry land. Bankers or wreckers would shine a light on shore to misdirect ships, which would then founder on the shore; the wreckers would then help themselves to the cargo. It is possible that these wreckers also killed any crew who protested. Nags Head, North Carolina, was named for the wreckers' practice of hanging a lantern on the head of a hobbled horse as it walked along the beach.

Popular theories
The following theories have been used in the past by the Triangle writers to explain myriad incidents:


Atlantis
An explanation for some of the disappearances pinned the blame on left-over technology from Atlantis. Reputed psychic Edgar Cayce claimed that evidence for Atlantis would be discovered just off Bimini in 1968. New Agers view the Bimini Road as either a road, wall, or pier meant to service ships bound for Atlantis from Central and South America, or a breakwater built to protect fishing boats. The wall may also have a natural origin.[14][15][16]


UFOs
Some theorists claim extraterrestrials are the reason of disappearances by abducting ships and aircraft. [citation needed] This was given a boost when topics like ESP, telekinesis, clairvoyance, and the like flowered in the middle-to-late 1960s, and was used as storylines for popular films like Close Encounters of the Third Kind and The UFO Incident.


Time warp
The proponents of this theory state that the many ships and planes entered a time warp to a different time or dimension on the other side, meaning that their crews could still be alive there, living new lives in another time period of the past or the future – or even possibly in a parallel universe. [citation needed] Usually, the ship or aircraft in the story enters this dimension by way of a cloud. This has been a popular subject in science fiction.


Anomalous phenomena
Charles Berlitz, grandson of a distinguished linguist and author of various additional books on anomalous phenomena, has kept in line with this extraordinary explanation, and attributed the losses in the Triangle to anomalous or unexplained forces.


Famous incidents
Main article: List of Bermuda Triangle incidents

Flight 19

US Navy TBF Grumman Avenger flight, similar to Flight 19. This photo had been used by various Triangle authors to illustrate Flight 19 itself. (US Navy)Main article: Flight 19
Flight 19 was a training flight of TBM Avenger bombers that went missing on December 5, 1945 while over the Atlantic. The impression is given that the flight encountered unusual phenomena and anomalous compass readings, and that the flight took place on a calm day under the leadership of an experienced pilot, Lt. Charles Carroll Taylor. Adding to the intrigue is that the Navy's report of the accident was ascribed to "causes or reasons unknown." It is believed that Charles Taylor's mother wanted to save Charles's reputation, so she made them write "reasons unknown" when actually Charles was 50 km NW from where he thought he was. [17]

While the basic facts of this version of the story are essentially accurate, some important details are missing. The weather was becoming stormy by the end of the incident; only Lt. Taylor had any significant flying time, but he was not familiar with the south Florida area and had a history of getting lost in flight, having done so three times during World War II, and being forced to ditch his planes twice into the water; and naval reports and written recordings of the conversations between Lt. Taylor and the other pilots of Flight 19 do not indicate magnetic problems.[17]


Mary Celeste
The mysterious abandonment in 1872 of the Mary Celeste is often but inaccurately connected to the Triangle, the ship having been abandoned off the coast of Portugal. Many theories have been put forth over the years to explain the abandonment, including alcohol fumes from the cargo and insurance fraud. The event is possibly confused with the sinking of a ship with a similar name, the Mari Celeste, off the coast of Bermuda on September 13, 1864, which is mentioned in the book Bermuda Shipwrecks by Dan Berg.


Ellen Austin
The Ellen Austin supposedly came across an abandoned derelict, placed on board a prize crew, and attempted to sail with it to New York in 1881. According to the stories, the derelict disappeared; others elaborating further that the derelict reappeared minus the prize crew, then disappeared again with a second prize crew on board. A check of Lloyd's of London records proved the existence of the Meta, built in 1854; in 1880 the Meta was renamed Ellen Austin. There are no casualty listings for this vessel, or any vessel at that time, that would suggest a large number of missing men placed on board a derelict which later disappeared.[18]


Teignmouth Electron
Main article: Donald Crowhurst

Teignmouth Electron, as she was on July 10, 1969.Donald Crowhurst was a sailor competing in the Sunday Times Golden Globe Race of 1968-69. His boat, a trimaran named Teignmouth Electron, left England on October 31, 1968; it was found abandoned south of the Azores on July 10, 1969. Most writers on the Triangle would stop there (only Winer elaborated on the facts), leaving out the evidence recovered from Crowhurst's logbooks which showed deception as to his position in the race and increasing irrationality. His last entry was June 29; it was assumed he jumped over the side a short time later.


USS Cyclops
Main article: USS Cyclops (AC-4)
The incident resulting in the single largest loss of life in the history of the U.S. Navy not related to combat occurred when USS Cyclops under the command of Lieutenant Commander G. W. Worley, went missing without a trace with a crew of 306 sometime after March 4, 1918, after departing the island of Barbados. Although there is no strong evidence for any theory, storms, capsizing and enemy activity have all been suggested as explanations.[19][20]


Theodosia Burr Alston
Main article: Theodosia Burr Alston
Theodosia Burr Alston was the daughter of former United States Vice-President Aaron Burr. Her disappearance has been cited at least once in relation to the Triangle, in The Bermuda Triangle by Adi-Kent Thomas Jeffrey (1975). She was a passenger on board the Patriot, which sailed from Charleston, South Carolina to New York City on December 30, 1812, and was never heard from again. Both Piracy and the War of 1812 have been posited as explanations, as well as a theory placing her in Texas, well outside the Triangle.


The Spray
Main article: Spray (sailing vessel)
Captain Joshua Slocum's skill as a mariner was beyond argument; he was the first man to sail around the world solo. In 1909, in his boat Spray he set out in a course to take him through the Caribbean to Venezuela. He disappeared; there was no evidence he was even in the Triangle when Spray was lost. It was assumed he was run down by a steamer or struck by a whale, the Spray being too sound a craft and Slocum too experienced a mariner for any other cause to be considered likely, and in 1924 he was declared legally dead. While a mystery, there is no known evidence for, or against, paranormal activity.


Carroll A. Deering
Main article: Carroll A. Deering

Schooner Carroll A. Deering, as seen from the Cape Lookout lightship on January 29, 1921, two days before she was found deserted in North Carolina. (US Coast Guard)A five-masted schooner built in 1919, the Carroll A. Deering was found hard aground and abandoned at Diamond Shoals, near Cape Hatteras, North Carolina on January 31, 1921. Rumors and more at the time indicated the Deering was a victim of piracy, possibly connected with the illegal rum-running trade during Prohibition, and possibly involving another ship, S.S. Hewitt, which disappeared at roughly the same time. Just hours later, an unknown steamer sailed near the lightship along the track of the Deering, and ignored all signals from the lightship. It is speculated that the Hewitt may have been this mystery ship, and possibly involved in the Deering crew's disappearance.[21]


Douglas DC-3
Main article: NC16002 disappearance
On December 28, 1948, a Douglas DC-3 aircraft, number NC16002, disappeared while on a flight from San Juan, Puerto Rico, to Miami. No trace of the aircraft or the 32 people onboard was ever found. From the documentation compiled by the Civil Aeronautics Board investigation, a possible key to the plane's disappearance was found, but barely touched upon by the Triangle writers: the plane's batteries were inspected and found to be low on charge, but ordered back into the plane without a recharge by the pilot while in San Juan. Whether or not this led to complete electrical failure will never be known. However, since piston-engined aircraft rely upon magnetos to provide electrical power and spark to their cylinders rather than batteries, this theory is unlikely.[22]


Star Tiger and Star Ariel
Main article: Star Tiger and Star Ariel
These Avro Tudor IV passenger aircraft disappeared without trace en route to Bermuda and Jamaica, respectively. Star Tiger was lost on January 30, 1948 on a flight from the Azores to Bermuda. Star Ariel was lost on January 17, 1949, on a flight from Bermuda to Kingston, Jamaica. Neither aircraft gave out a distress call; in fact, their last messages were routine. A possible clue to their disappearance was found in the mountains of the Andes in 1998: the Star Dust, an Avro Lancastrian airliner run by the same airline, had disappeared on a flight from Buenos Aires, Argentina, to Santiago, Chile on August 2, 1947. The plane's remains were discovered at the melt end of a glacier, suggesting that either the crew did not pay attention to their instruments, suffered an instrument failure or did not allow for headwind effects from the jetstream on the way to Santiago when it hit a mountain peak, with the resulting avalanche burying the remains and incorporating it into the glacier. However, this is mere speculation with regard to the Star Tiger and Star Ariel, pending the recovery of the aircraft. It should be noted that the Star Tiger was flying at a height of just 2,000 feet, which would have meant that if the plane was forced down, there would have been no time to send out a distress message. It is also far too low for the jetstream or any other high-altitude wind to have any effect.[23]


KC-135 Stratotankers
On August 28, 1963 a pair of U.S. Air Force KC-135 Stratotanker aircraft collided and crashed into the Atlantic. The Triangle version (Winer, Berlitz, Gaddis) of this story specifies that they did collide and crash, but there were two distinct crash sites, separated by over 160 miles of water. However, Kusche's research showed that the unclassified version of the Air Force investigation report stated that the debris field defining the second "crash site" was examined by a search and rescue ship, and found to be a mass of seaweed and driftwood tangled in an old buoy.


SS Marine Sulphur Queen
Main article: SS Marine Sulphur Queen
SS Marine Sulphur Queen, a T2 tanker converted from oil to sulfur carrier, was last heard from on February 4, 1963 with a crew of 39 near the Florida Keys. Marine Sulphur Queen was the first vessel mentioned in Vincent Gaddis' 1964 Argosy Magazine article, but he left it as having "sailed into the unknown", despite the Coast Guard report which not only documented the ship's badly-maintained history, but declared that it was an unseaworthy vessel that should never have gone to sea.[24][25]





Raifuku Maru
One of the more famous incidents in the Triangle took place in 1921 (some say a few years later), when the Japanese vessel Raifuku Maru (sometimes misidentified as Raikuke Maru) went down with all hands after sending a distress signal which allegedly said "Danger like dagger now. Come quick!", or "It's like a dagger, come quick!" This has led writers to speculate on what the "dagger" was, with a waterspout being the likely candidate (Winer). In reality the ship was nowhere near the Triangle, nor was the word "dagger" a part of the ship's distress call ("Now very danger. Come quick."); having left Boston for Hamburg, Germany, on April 21, 1925, she got caught in a severe storm and sank in the North Atlantic with all hands while another ship, RMS Homeric, attempted an unsuccessful rescue.


Connemara IV
A pleasure yacht found adrift in the Atlantic south of Bermuda on September 26, 1955; it is usually stated in the stories (Berlitz, Winer) that the crew vanished while the yacht survived being at sea during three hurricanes. The 1955 Atlantic hurricane season lists only one storm coming near Bermuda towards the end of August, hurricane "Edith"; of the others, "Flora" was too far to the east, and "Katie" arrived after the yacht was recovered. It was confirmed that the Connemara IV was empty and in port when "Edith" may have caused the yacht to slip her moorings and drift out to sea.
