Scientific Mysteries! The Bermuda Triangle!

The Bermuda Triangle, also known as the Devil's Triangle, is a region in the western part of the North Atlantic Ocean where a number of aircraft and surface vessels allegedly disappeared under mysterious circumstances. Popular culture has attributed these disappearances to the paranormal or activity by extraterrestrial beings. Documented evidence indicates that a significant percentage of the incidents were inaccurately reported or embellished by later authors, and numerous official agencies have stated that the number and nature of disappearances in the region is similar to that in any other area of ocean.

Natural explanations

Compass variations

Compass problems are one of the cited phrases in many Triangle incidents. While some have theorized that unusual local magnetic anomalies may exist in the area, such anomalies have not been shown to exist. Compasses have natural magnetic variations in relation to the magnetic poles, a fact which navigators have known for centuries. Magnetic (compass) north and geographic (true) north are only exactly the same for a small number of places – for example, as of 2000 in the United States only those places on a line running from Wisconsin to the Gulf of Mexico. But the public may not be as informed, and think there is something mysterious about a compass "changing" across an area as large as the Triangle, which it naturally will.

Deliberate acts of destruction

Deliberate acts of destruction 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 various command log books, many others 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 inWorld War II, were attributed to submarines, but no such link has been found in the German records.
Piracy—the illegal capture of a craft on the high seas—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. Piracy in the Caribbean was common from about 1560 to the 1760s, and famous pirates included Edward Teach (Blackbeard) and Jean Lafitte.

Gulf Stream

The Gulf Stream is a deep ocean current that originates in the Gulf of Mexico and then flows 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. It has a surface velocity of up to about 2.5 metres per second (5.6 mi/h). A small plane making a water landing or a boat having engine trouble can be carried away from its reported position by the current.

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 benzeneresidue as a reason for the loss of the tanker SS 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.

Hurricanes

Hurricanes are powerful storms, which form in tropical waters and have historically cost thousands of lives lost and caused 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. These storms have in the past caused a number of incidents related to the Triangle.

Methane hydrates

An explanation for some of the disappearances has focused on the presence of vast fields of methane hydrates (a form of natural gas) 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; 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.
Publications by the USGS describe large stores of undersea hydrates worldwide, including the Blake Ridge area, off the southeastern United States coast. However, according to another of their papers, no large releases of gas hydrates are believed to have occurred in the Bermuda Triangle for the past 15,000 years.

Rogue waves

In various oceans around the world, rogue waves have caused ships to sink and oil platforms to topple. These waves, until 1995, were considered to be a mystery and/or a myth.

Notable incidents

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. 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. The planned route is well outside all but the most extended versions of the Bermuda Triangle. 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.

Mary Celeste

The mysterious abandonment in 1872 of the 282-ton brigantine Mary Celeste is often but inaccurately connected to the Triangle, the ship having been abandoned off the coast of Portugal. The event is possibly confused with the loss of a ship with a similar name, the Mari Celeste, a 207-ton paddle steamer that hit a reef and quickly sank off the coast of Bermuda on September 13, 1864. Kusche noted that many of the "facts" about this incident were actually about the Marie Céleste, the fictional ship from Arthur Conan Doyle's short story "J. Habakuk Jephson's Statement" (based on the realMary Celeste incident, but fictionalised).

Ellen Austin

The Ellen Austin supposedly came across a derelict ship, 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 from Lloyd's of London records proved the existence of theMeta, built in 1854 and that 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 were placed on board a derelict that later disappeared.

USS Cyclops

The incident resulting in the single largest loss of life in the history of the US Navy not related to combat occurred when USS Cyclops, under the command of Lt CdrG.W. Worley, went missing without a trace with a crew of 309 sometime after March 4, 1918, after departing the island of Barbados. Although there is no strong evidence for any single theory, many independent theories exist, some blaming storms, some capsizing, and some suggesting that wartime enemy activity was to blame for the loss.

Carroll A. Deering

A five-masted schooner built in 1919, the Carroll A. Deering was found hard aground and abandoned at Diamond Shoals, near Cape HatterasNorth 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 duringProhibition, 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.

Flight 19

Flight 19 was a training flight of TBM Avenger bombers that went missing on December 5, 1945, while over the Atlantic. The squadron's flight path was scheduled to take them due east for 120 miles, north for 73 miles, and then back over a final 120-mile leg that would return them to the naval base, but they never returned. 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 supervision of an experienced pilot, Lt. Charles Carroll Taylor. Adding to the intrigue is that the Navy's report of the accident ascribed it to "causes or reasons unknown."
Adding to the mystery, a search and rescue Mariner aircraft with a 13-man crew was dispatched to aid the missing squadron, but the Mariner itself was never heard from again. Later, there was a report from a tanker cruising off the coast of Florida of a visible explosion at about the time the Mariner would have been on patrol.
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, and naval reports and written recordings of the conversations between Taylor and the other pilots of Flight 19 do not indicate magnetic problems.

Star Tiger and Star Ariel

G-AHNP Star Tiger disappeared on January 30, 1948 on a flight from the Azores to Bermuda; G-AGRE Star Ariel disappeared on January 17, 1949, on a flight from Bermuda to Kingston, Jamaica. Both were Avro Tudor IV passenger aircraft operated by British South American Airways. Both planes were operating at the very limits of their range and the slightest error or fault in the equipment could keep them from reaching the small island. One plane was not heard from long before it would have entered the Triangle.

Douglas DC-3

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 spark to their cylinders rather than a battery powered ignition coil system, this theory is not strongly convincing.

KC-135 Stratotankers

On August 28, 1963, a pair of US 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 (260 km) 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

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.

Connemara IV

A pleasure yacht was 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 shows Hurricane Ione passing nearby between the 14th and 18th of that month, with Bermuda being affected by winds of almost gale force. It was confirmed that the Connemara IV was empty and in port when Ione may have caused the yacht to slip her moorings and drift out to sea.
