Fungi
Eumycota: mushrooms, sac fungi, yeast, molds, rusts, smuts, etc.
Meredith Blackwell, Rytas Vilgalys, Timothy Y. James, and John W. TaylorThe root of the current tree connects the organisms featured in this tree to their containing group and the rest of the Tree of Life. The basal branching point in the tree represents the ancestor of the other groups in the tree. This ancestor diversified over time into several descendent subgroups, which are represented as internal nodes and terminal taxa to the right.

Containing group: Eukaryotes
Introduction
The organisms of the fungal lineage include mushrooms, rusts, smuts, puffballs, truffles, morels, molds, and yeasts, as well as many less well-known organisms (Alexopoulos et al., 1996). More than 70,000 species of fungi have been described; however, some estimates of total numbers suggest that 1.5 million species may exist (Hawksworth, 1991; Hawksworth et al., 1995).As the sister group of animals and part of the eukaryotic crown group that radiated about a billion years ago, the fungi constitute an independent group equal in rank to that of plants and animals. They share with animals the ability to export hydrolytic enzymes that break down biopolymers, which can be absorbed for nutrition. Rather than requiring a stomach to accomplish digestion, fungi live in their own food supply and simply grow into new food as the local environment becomes nutrient depleted.
Most biologists have seen dense filamentous fungal colonies growing on rich nutrient agar plates, but in nature the filaments can be much longer and the colonies less dense. When one of the filaments contacts a food supply, the entire colony mobilizes and reallocates resources to exploit the new food. Should all food become depleted, sporulation is triggered. Although the fungal filaments and spores are microscopic, the colony can be very large with individuals of some species rivaling the mass of the largest animals or plants.

Prior to mating in sexual reproduction, individual fungi communicate with other individuals chemically via pheromones. In every phylum at least one pheromone has been characterized, and they range from sesquiterpines and derivatives of the carotenoid pathway in chytridiomycetes and zygomycetes to oligopeptides in ascomycetes and basidiomycetes.Within their varied natural habitats fungi usually are the primary decomposer organisms present. Many species are free-living saprobes (users of carbon fixed by other organisms) in woody substrates, soils, leaf litter, dead animals, and animal exudates. The large cavities eaten out of living trees by wood-decaying fungi provide nest holes for a variety of animals, and extinction of the ivory billed woodpecker was due in large part to loss, through human activity, of nesting trees in bottom land hardwoods. In some low nitrogen environments several independent groups of fungi have adaptations such as nooses and sticky knobs with which to trap and degrade nematodes and other small animals. A number of references on fungal ecology are available (Carroll and Wicklow, 1992; Cooke and Whipps, 1993; Dix and Webster, 1995).
However, many other fungi are biotrophs, and in this role a number of successful groups form symbiotic associations with plants (including algae), animals (especially arthropods), and prokaryotes. Examples are lichens, mycorrhizae, and leaf and stem endophytes. Although lichens may seem infrequent in polluted cities, they can form the dominant vegetation in nordic environments, and there is a better than 80% chance that any plant you find is mycorrhizal. Leaf and stem endophytes are a more recent discovery, and some of these fungi can protect the plants they inhabit from herbivory and even influence flowering and other aspects of plant reproductive biology. Fungi are our most important plant pathogens, and include rusts, smuts, and many ascomycetes such as the agents of Dutch elm disease and chestnut blight. Among the other well known associations are fungal parasites of animals. Humans, for example, may succumb to diseases caused by Pneumocystis (a type of pneumonia that affects individuals with supressed immune systems), Coccidioides (valley fever), Ajellomyces (blastomycosis and histoplasmosis), and Cryptococcus (cryptococcosis) (Kwon-Chung and Bennett, 1992).

Fungal spores may be actively or passively released for dispersal by several effective methods. The air we breathe is filled with spores of species that are air dispersed. These usually are species that produce large numbers of spores, and examples include many species pathogenic on agricultural crops and trees. Other species are adapted for dispersal within or on the surfaces of animals (particularly arthropods). Some fungi are rain splash or flowing water dispersed. In a few cases the forcible release of spores is sufficient to serve as the dispersal method as well. The function of some spores is not primarily for dispersal, but to allow the organisms to survive as resistant cells during periods when the conditions of the environment are not conducive to growth.Fungi are vital for their ecosystem functions, some of which we have reviewed in the previous paragraphs. In addition a number of fungi are used in the processing and flavoring of foods (baker's and brewer's yeasts, Penicillia in cheese-making) and in production of antibiotics and organic acids. Other fungi produce secondary metabolites such as aflatoxins that may be potent toxins and carcinogens in food of birds, fish, humans, and other mammals.
A few species are studied as model organisms that can be used to gain knowledge of basic processes such as genetics, physiology, biochemistry, and molecular biology with results that are applicable to many organisms (Taylor et al., 1993). Some of the fungi that have been intensively studied in this way include Saccharomyces cereviseae, Neurospora crassa, and Ustilago maydis.
Most phyla appear to be terrestrial in origin, although all major groups have invaded marine and freshwater habitats. An exception to this generality is the flagellum-bearing phyla Chytridiomycota, Blastocladiomycota, and Neocallimastigomycota (collectively referred to as chytrids), which probably had an aquatic origin. Extant chytrid species also occur in terrestrial environments as plant pathogenic fungi, soil fungi, and even as anaerobic inhabitants of the guts of herbivores such as cows (all Neocallimastigomycota).
Characteristics
Fungi are characterized by non-motile bodies (thalli) constructed of apically elongating walled filaments (hyphae), a life cycle with sexual and asexual reproduction, usually from a common thallus, haploid thalli resulting from zygotic meiosis, and heterotrophic nutrition. Spindle pole bodies, not centrioles, usually are associated with the nuclear envelope during cell division. The characteristic wall components are chitin (beta-1,4-linked homopolymers of N-acetylglucosamine in microcrystalline state) and glucans primarily alpha-glucans (alpha-1,3- and alpha-1,6- linkages) (Griffin, 1994).Click on an image to view larger version & data in a new window

Exceptions to this characterization of fungi are well known, and include the following: Most species of chytrids have cells with a single, smooth, posteriorly inserted flagellum at some stage in the life cycle, and centrioles are associated with nuclear division. The life cycles of most chytrids are poorly studied, but some (Blastocladiomycota) are known to have zygotic meiosis (therefore, alternation between haploid and diploid generations). Certain members of Mucoromycotina, Ascomycota, and Basidiomycota may lack hyphal growth during part or all of their life cycles, and, instead, produce budding yeast cells. Most fungal species with yeast growth forms contain only minute amounts of chitin in the walls of the yeast cells. A few species of Ascomycota (Ophiostomataceae) have cellulose in their walls, and certain members of Blastocladiomycota and Entomophthoromycotina lack walls during part of their life cycle (Alexopoulos et al., 1996).Fossil Record
Based on the available fossil record, fungi are presumed to have been present in Late Proterozoic (900-570 mya). Terrestrial forms of purported ascomycetes are reported in associations with microarthropods in the Silurian Period (438-408 mya) (Sherwood-Pike and Gray, 1985). Fossil hyphae in association with wood decay and fossil chytrids and Glomales-Endogonales representatives associated with plants of the Rhynie Chert are reported from the Devonian Period (408-360 mya) (Hass et al., 1994; Remy et al., 1994a, 1994b; Taylor et al., 1994a, 1995b). Fungal fossil diversity increased throughout the Paleozoic Era (Taylor et al., 1994b) with all modern classes reported in the Pennsylvanian Epoch (320-286 mya).A first attempt to match molecular data on fungal phylogeny to the geological record shows general agreement, but does point out some conflicts between the two types of data (Berbee and Taylor 1993).
Biogeography
Wherever adequate moisture, temperature, and organic substrates are available, fungi are present. Although we normally think of fungi as growing in warm, moist forests, many species occur in habitats that are cold, periodically arid, or otherwise seemingly inhospitable. It is important to recognize that optimum conditions for growth and reproduction vary widely with fungal species. Diversity of most groups of fungi tends to increase in tropical regions, but detailed studies are only in their infancy (Isaac et al., 1993).Although many saprobic and plant pathogenic species with low substrate specificity and effective dispersal systems have broad distributions, gene flow appears to be restricted in many fungi. For these species large bodies of water such as the Atlantic and Pacific Oceans create barriers to gene exchange. Some distributions are limited by substrate availability, and dramatic examples come from parasites of Gondowanan plants; one of these is the Southern Hemisphere distribution of the ascomycete Cyttaria, corresponding with part of the distribution of its host plant Nothofagus. The fossil record shows that fungi were present in Antarctica, as is the case for other organisms with Gondwanan distributions. Arthropod associates also may show distributions throughout part or all of a host range, and some fungal species (ex. wood wasp associates) occur outside the range of the associated arthropod.
Notable Fungi
- The largest known basidioma (mushroom or fruiting body) was that of a Rigidioporus ulmarius (Agaricomycetes), hidden-away in a shady corner of the Royal Botanic Gardens, Kew, Richmond, Surrey, England. This fruiting body was mentioned in the Guinness Book of World Records (Matthews, 1994). At the beginning of every New Year the Annual Mensuration Ceremony of the fruiting body took place, and on 19 January 1996 it had increased to 170 cm maximum length (up from 159 in 1995) and 146 cm maximum width (up from 140 in 1995). It also grew 4 cm taller from the soil level, measuring 54 cm. The weight of the fruiting body was estimated to be 284 kg (625 pounds)! Amid rumors of its destruction, Dr. Brian M. Spooner, Head of Mycology, Royal Botanic Gardens, has brought us up to date on the fate of the record specimen. Unfortunately, the basidioma began to rot at the edges a few years ago, likely because the hyphal body of the fungus digested away its elm root substrate, reminding us that a fungus needs a good dispersal system to escape the substrate that eventually inevitably is destroyed. In the life of the fruiting body many trillions of spores must have been produced, and some of these surely fell on an appropiate substrate to establish a new infection. The final insult to the fruiting body came from a fox that burrowed under one side and caused it to collapse.Other large basidiomata are those of a Canadian puffball almost 9 feet in circumference (over 48 pounds) and a basidiocarp of the sulfur mushroom in England (100 pounds). A previous Guinness Book of World Records record-sized fruiting body of Bridgeoporus nobilissimus, an endangered species of the Pacific Northwest of the United States, is over 160 kg (300 pounds) and may have regained the title of “largest” with the demise of the Kew specimen. This polypore also may do itself in because its great weight is likely to eventually cause it to fall as the mycelium depletes its food source, often the noble fir tree.
- Reproductive structures clearly can be very large, but what about the body of the fungus, which often is hidden from view within the substrate? One fungus body constructed of tubular filaments (hyphae) was brought to our attention when molecular techniques were used to show that it was extensive (37 acres and an estimated blue whale equivalent size of 110 tons). The Michigan fungus clone (Armillaria bulbosa, Agaricomycetes) grew in tree roots and soil. This report drew attention to an even larger fungal clone of Armillaria ostoyae, reported earlier in the state of Washington, which covered over 1,500 acres. Each clone began from the germination of a single spore over a thousand years ago. Although they probably have fragmented and are no longer continuous bodies, such organisms give us cause to think about what constitutes an individual.
- Penicillium chrysogenum (Ascomycota) is known for its production of the antibiotic penicillin. Although other antibiotics are produced by a variety of organisms, penicillin was the first to be developed. In the spring of 1996 a long dried out culture of the original isolate prepared by its discoverer, Sir Alexander Fleming in the late 1920s, was auctioned by Sotheby's of London and sold to a pharmaceutical company for 23,000 pounds. This price is insignificant when one considers the worth of this fungus, not only in sales of penicillin, but in terms of illnesses cured and lives saved. In the past a simple scratch or blister sometimes could result in a fatal infection such as the blister that resulted in the death of John Calvin Coolidge (1918-1924), the son of a U. S. president. However, misuse of penicillin and other antibiotics has resulted in selection of resistant microorganisms, and the threat of untreatable bacterial infections and diseases (for example Staphylococcus aureus and Escherichia coli and tuberculosis and syphilis) is still present in our homes and recreation areas.
- Fungal spores fill the air we breathe. On many days in some localities the number of fungal spores in the air far exceeds the pollen grains. Fungal spores also cause allergies; however, unlike seasonal pollen production, some fungi can produce spores all year long. The largest number of fungal spores ever sampled was over 5.5 million per cubic foot in Wales (Matthews, 1994).
- Basidiomycetes have always attracted a lot of attention because some of them have large basidiocarps, but the realization that all fungi are important in ecosystem function has drawn more attention to microscopic forms as well. For example a report on the secret sex life of a yeast-like ascomycete human pathogen, Coccidioides immitis, made a headline of the New York Times (6 February 1996, p. B7). This fungus causes Valley Fever and is endemic in parts of the southwestern United States. Although no one has been able to observe sexual reproduction in this species, molecular studies show genetic diversity that is best explained by occurrence of sexual reproduction in the life cycle.
- Another yeast-like ascomycete reported in the Dallas Morning News (28 August 1995, p. 8D) lives in the gut of cigar beetles and is essential to the beetle's health. Without the gut fungi to detoxify the plant material of toxins, the beetles would be poisoned. Keep on the lookout for other reports of fascinating fungal feats.
Discussion of Phylogenetic Relationships
The kingdom Fungi is a diverse clade of heterotrophic organisms that shares some characters with animals such as chitinous structures, storage of glycogen, and mitochondrial codon UGA encoding tryptophan. Both animals and fungi have spores or gametes with a single smooth, posteriorly inserted flagellum, but only species of the basal chytrid phyla have retained this primitive character (Barr, 1992; Cavalier-Smith, 1987, 1995). Fungi, animals, and other heterotrophic protist-like organisms such as choanoflagellates and Mesomycetozoea are now considered part of the larger group termed opisthokonts (Cavalier-Smith, 1987) in reference to the posterior flagellum.The branch uniting the fungi and animals is well-supported based on a number of molecular phylogenetic datasets, including the nuclear small subunit ribosomal RNA gene (Wainwright et al., 1993; Bruns et al. 1993), unique and shared sequence insertions in proteins such as elongation factor 1α (Baldauf and Palmer, 1993), entire mitochondrial genomes (Lang et al., 2002), and concatenated protein-coding genes (Steenkamp et al., 2006).
Prior classification systems of Fungi based primarily on morphology are in need of updating to more accurately reflect phylogenetic relationships as determined by molecular systematics. Molecular characters have been essential for phylogenetic analysis in cases when morphological characters are convergent, reduced, or missing among the taxa considered. This is especially true of species that never reproduce sexually, because characters of sexual reproduction traditionally have been the basis for classification of Fungi. Use of molecular characters allows asexual fungi to be placed among their closest relatives.
Previous classifications placed early-diverging fungal groups (non-Ascomycota or Basidiomycota) into two phyla: Chytridiomycota and Zygomycota. Numerous phylogenetic studies now suggest that neither is monophyletic, and the latest classification scheme includes six phyla and an additional four unplaced subphyla (Hibbett et al., 2007). At present, because of the ancient divergence times between the fungal phyla, the exact phylogenetic relationships are ambiguous. Chytrids appear to be a paraphyletic group at the base of the fungal phylogeny and merely fungal lineages which have retained the character of flagellated spores. Three phyla of flagellated fungi are proposed (Blastocladiomycota, Chytridiomycota, and Neocallimastigomycota; Hibbett et al., 2007) and two chytrid genera Olpidium and Rozella, are of uncertain phylogenetic position (James et al., 2006a, 2006b). These genera are interesting because they are both highly reduced endoparasites (living inside the host cell) whose entire thallus consists of only a spherical body absorbing nutrients from the host material that surrounds it. Rozella appears in an isolated position in the fungal phylogeny as the very earliest lineage to diverge from the rest of the fungi (James et al., 2006a, 2006b). In contrast, Olpidium brassicae appears to have diverged after the majority of chytrids and is more closely related to some zygomycete fungi (James et al., 2006a, 2006b).

Evidence from shared morphological characters such as regularly septate hyphae and a dikaryotic stage (two separate and different nuclei in a single hyphal segment) in the life cycle usually has been interpreted as support for a close relationship between Basidiomycota and Ascomycota. Numerous phylogenetic studies such as SSU rDNA (Berbee and Taylor, 1992), RNA polymerase genes (Liu et al., 2006), and mitochondrial genome sequencing (Seif et al., 2005) provide strong support for this relationship. A subkingdom termed Dikarya is proposed (Hibbett et al., 2007), creating a division between a highly speciose subkingdom (Dikarya) and the remaining early diverging lineages whose relationships are not precisely known.
Fungal classification is far from static, and even which organisms are actually members of Fungi is changing. For example, the group trichomycetes describes gut inhabitants of arthropods that share similarities with zygomycetes. Molecular phylogenetic studies have demonstrated that two of the four orders of trichomycetes are actually members of the Mesomycetozoea protist group (Benny and O’Donnell, 2000; Cafaro, 2005). Other organisms that were previously considered to be Fungi because of their heterotrophic, mold-like growth forms are now classified as stramenopiles (Oomycota, Hyphochytriomycota, and Labyrinthulomycota) or slime molds (Myxomycota, Plasmodiomycota, Dictyosteliomycota, Acrasiomycota) (Bhattacharya et al., 1992; Leipe et al., 1994; Van der Auwera et al., 1995). More interesting for mycologists are the findings that some species previously considered protozoa are actually Fungi. For example, the species Hyaloraphidium curvatum was assumed to be a green alga that had adopted a heterotrophic lifecycle concomitantly with losing its chloroplast. It is now known to be a chytrid fungus related to Monoblephariomycetes but lacking a flagellated stage (Ustinova et al., 2000). Other examples include the parasitic organisms presumed to be protozoa, such as the cockroach parasite Nepridiophaga (Wylezich et al., 2004) and the Daphnia parasite Polycarum (Johnson et al., 2006) recently demonstrated to be members of the fungal kingdom based on SSU rDNA phylogenies.
The most revolutionary addition to the fungal lineage has occurred with phylogenetic evidence indicating the protist group microsporidia is closely related to Fungi–possibly derived from zygomycetes (Keeling, 2003) or sister to the genus Rozella on the earliest branch in the fungal kingdom (James et al., 2006a). Microsporidia are highly specialized intracellular parasites (primarily of animals) that lack mitochondria but have chitin and trehalose in their spores (similar to Fungi). All molecular studies have shown that microsporidia evolve at an extremely accelerated rate of evolution, making their placement in the Tree of Life difficult. The relationship with fungi is supported by many single and multiple gene phylogenies (e.g., Liu et al., 2006), but an exact placement within the fungi has not received strong support (Keeling and Fast, 2002).
More recently the nuclearid amoebae have been demonstrated to be a sister group to the Fungi with strong support (Steenkamp et al., 2006). This finding is significant because Nuclearia lacks a cell wall and has phagotrophic nutrition in which the food source (such as a bacterium or algal cell) is engulfed wholly, unlike fungi and microsporidia which utilize absorptive nutrition. Further sampling of basal fungal lineages will be needed to determine whether a Nuclearia-like organism was the cenancestor (most recent common ancestor) of Fungi.

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, Europe, and 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 hurricanes strike 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.
- 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 Gutierrez, 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 Sanchez 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...
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"; 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.
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.
- 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.
Methane gas can also crash planes. The less dense air causes planes to lose lift. Also, the altimeter of planes (the instrument that measures the altitude) functions on the density of air. Because methane is less dense, the altimeter assumes the plane is climbing. Planes at night or in the clouds, where they can't see the ground, assume that they are climbing and dive, causing them to crash. Also, methane in the engine throws off the mix of fuel and air. Aircraft engines burn hydrocarbons (gasoline or jet fuel) with oxygen provided by the air. When the ambient oxygen levels drop, combustion can stop, and the engine stalls. All of these effects of methane gas have been shown experimentally.
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.
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. 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.
Research has shown that freak waves up to 30 m (100 feet) tall, capable of sinking the largest ships within moments, can and do happen. Although these are very rare, in some areas ocean currents mean they happen more often than the norm. Such waves have now been hypothesized as a cause for many unexplained shipping losses over the years.
The book was a best seller, and many interested readers offered theories to explain the nature of the disappearances. The list includes natural storms, transportation by extraterrestrial technology, high-traffic volumes (and correspondingly high accident rates), a "temporal hole," the lost Atlantis empire from the bottom of the ocean, and other natural and supernatural causes.
The Triangle's location in the Caribbean makes it subject to unpredictable weather patterns. This takes us to Earth changes and the excalation of intense hurricanes in 2005 with more to come in the years ahead.
These weather extremes prey on inexperienced navigators and smaller boats and planes. Water spouts, sudden electrical and thunder storms, and the like, can cause havoc in the area. The Gulf Stream can also be brutal in that region and perhaps has swept away evidence of natural disasters.
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.
Other writers attribute the events to UFOs. This idea was used by Steven Spielberg for his film Close Encounters of the Third Kind, which features the lost Flight 19 as alien abductees.
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.
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 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 Taylor and the other pilots of Flight 19 do not indicate magnetic problems.
On December 5th, 1945, five Avenger torpedo bombers lifted into the air from the Navel Air Station at Fort Lauderdale, Florida, at 2:10 in the afternoon. It was a routine practice mission and the flight was composed of all students except for the Commander, a Lt. Charles Taylor.
The mission called for Taylor and his group of 13 men to fly due east 56 miles to Hens and Chicken Shoals to conduct practice bombing runs. When they had completed that objective, the flight plan called for them to fly an additional 67 miles east, then turn north for 73 miles and finally straight back to base, a distance of 120 miles. This course would take them on a triangular path over the sea.
About an hour and a half after the flight had left, a Lt. Robert Cox picked up a radio transmission from Taylor. Taylor indicated that his compasses were not working, but he believed himself to be somewhere over the Florida Keys (the Keys are a long chain of islands south of the Florida mainland). Cox urged him to fly north, toward Miami, if Taylor was sure the flight was over the Keys.
Planes today have a number of ways that they can check their current position including listening to a set of GPS (Global Positioning Satellites) in orbit around the Earth. It is almost impossible for a pilot to get lost if he has the right equipment and uses it properly.
In 1945, though, planes flying over water had to depend on knowing their starting point, how long and fast they had flown, and in what direction. If a pilot made a mistake with any of these figures, he was lost. Over the ocean there were no landmarks to set him right.
Apparently Taylor had become confused at some point in the flight. He was an experienced pilot, but hadn't spent a lot of time flying east toward the Bahamas which was where he was going on that day. For some reason Taylor apparently thought the flight had started out in the wrong direction and had headed south toward the Florida Keys, instead of east. This thought was to color his decisions throughout the rest of the flight with deadly results.
The more Taylor took his flight north to try to get out of the Keys, the further out to sea the Avengers actually traveled. As time went on, snatches of transmissions were picked up on the mainland indicating the other Flight 19 pilots were trying to get Taylor to change course. "If we would just fly west," one student told another, "we would get home." He was right.
By 4:45 P.M. it was obvious to the people on the ground that Taylor was hopelessly lost. He was urged to turn control of the flight over to one of his students, but apparently he didn't. As it grew dark, communications deteriorated. From the few words that did get through it was apparent Taylor was still flying north and east, the wrong directions.
At 5:50 P.M. the ComGulf Sea Frontier Evaluation Center managed get a fix on Flight 19's weakening signals. It was apparently east of New Smyrna Beach, Florida. By then communications were so poor that this information could not be passed to the lost planes.
At 6:20 a Dumbo Flying Boat was dispatched to try and find Flight 19 and guide it back. Within the hour two more planes, Martin Mariners, joined the search. Hope was rapidly fading for Flight 19 by then. The weather was getting rough and the Avengers were very low on fuel.
The two Martin Mariners were supposed to rendezvous at the search zone. The second one, designated Training 49, never showed up.
The last transmission from Flight 19 was heard at 7:04 P.M. Planes searched the area through the night and the next day. There was no sign of the Avengers.
What happened to the missing Martin Mariner? The crew of the SS Gaines Mill observed an explosion over the water shortly after the Mariner had taken off. They headed toward the site and there they saw what looked like oil and airplane debris floating on the surface. None of it was recovered because of the bad weather, but there seems little doubt this was the remains of the Mariner. The plane had a reputation as being a 'flying bomb' which would burst into flame from even a single, small spark. Speculation is that one of 22 men on board, unaware that the unpressurized cabin contained gas fumes, lit a cigarette, causing the explosion.
So how did this tragedy turn into a Bermuda Triangle mystery? The Navy's original investigation concluded the accident had been caused by Taylor's confusion. Taylor's mother refused to accept that and finally got the Navy to change the report to read that the disaster was for "causes or reasons unknown." This may have spared the woman's feelings, but blurred the actual facts.
The saga of Flight 19 is probably the most repeated story about the Bermuda Triangle. The planes, and their pilots, even found their way into the science fiction film classic, 'Close Encounters of the Third Kind.'
Where is Flight 19 now? In 1991 five Avengers were found in 600 feet of water off the coast of Florida by the salvage ship Deep Sea. Examination of the planes showed that they were not Flight 19, however, so the final resting place of the planes, and their crews is still the Bermuda Triangle's secret.
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 (610 m), 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.
The Coast Guard is also officially skeptical of the Triangle, noting that they collect and publish, through their inquiries, much documentation 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 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).
The NOVA / Horizon episode The Case of the Bermuda Triangle (June 27, 2006) was highly critical stating that "When we've gone back to the original sources or the people involved the mystery evaporates. Science does not have to answer questions about the Triangle because those questions are not valid in the first place. ... Ships and planes behave in the Triangle the same way they behave everywhere else in the world"
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 favor of books, TV specials, et cetera. which support the Triangle mystery and against well-researched material if it espouses a skeptical viewpoint.
Finally, if the Triangle is assumed to cross land, such as parts of Puerto Rico, the Bahamas, or Bermuda itself, there is no evidence for the disappearance of any land-based vehicles or persons. Located inside the Triangle, Freeport operates a major shipyard, an airport which yearly handles 50,000 flights and is visited by over a million tourists annually.

Contrary to several claims, neither the Devil's Sea nor the Bermuda Triangle is located on the agonic line, where the magnetic north equals the geographic north. The magnetic declination in this area is about 6 degrees. As is the case with all things mysterious, there are many theories regarding the Devil's Sea. One of the most prominent is that there is a large amount of volcanic activity around the area, and an underwater volcano could obliterate a ship without a trace.
Christopher Columbus wrote in his diary about this sea. In fact, it so fooled his crew that it almost led them to mutiny. There exists the possibility exists of never leaving this legendary sea, he wrote. Another fascinating feature he noted is its ability to draw things in from all over the Atlantic. Some even claim it to be the "catch-basin" of the Atlantic.
Columbus' crew was greatly disappointed when seaweed and land birds were sighted, but after a few days no land was to be seen. Soon after, Columbus wrote, My compass acts strangely. I will not report this to my crew because of their deep superstitions about the area. Days later, Columbus saw a large meteor fall from the sky. He wrote, A large ball of light has fallen from the sky. It is unsure whether he mentions this occurrence in awe, because of its great size, or in fright. Later on their journey, in that area, Columbus and several of his crew members sighted unexplained dancing lights on the horizon. They wandered around for over a week before finally sighting land.
There are numerous stories of the supposed appearance of strange creatures, unexplained vanishings, time standing still, slowing to a crawl, or speeding up, or other weird happenings.
One well-documented and well-known case includes that of Captain George R. Donner, who commanded the Great Lakes freighter O.M. McFarland. While on a journey back from Erie, Pennsylvania after picking up 9,800 tons of coal, the ship made course westward through the lakes. It was slow going due to late-spring ice floes, but the ship was making steady progress toward its destination, Port Washington, Wisconsin, when Donner disappeared.
On the night of April 28, 1937, the captain took to his cabin, with instructions to be awakened as the ship drew near to port. About three hours later, with Port Washington growing close, the second mate appeared at the captain's cabin, prepared to awake him, but found no one. He and the crew searched the ship, but the captain was nowhere to be seen. The mate reported that the cabin door was locked from the inside, adding to the mystery of the triangle. Reportedly, the ship was in the dead center of the triangle when the captain disappeared.
Another disappearance took place on June 23, 1950, and involved a Northwest Airlines DC-4 aircraft carrying fifty-five passengers and three crew members. This flight 2501 had departed from New York City and was due to land at Minneapolis. The last radio contact recorded with the plane was that it was 3,500 feet over Battle Creek, Michigan and was going to change its course to a northwesterly path over Lake Michigan, due to bad weather near Chicago. After this, the plane was never seen again, nor were the occupants. Even after an extensive search by the Coast Guard, only a blanket with the airline's logo was found. Once again, the aircraft was in the center of the supposed triangle when it disappeared.
Paranormal Theories
Edgar Cayce said that the Bahama Banks were the last part of Atlantis to sink, and the last place where these glorious advanced electromagnetic machines went below the ocean. He prophezied that elements of Atlantis would rise in 1968 and 1969. The Bimini Wall or Road was discovered off the coast of Bimini in 1968.
The electromagnetic anomalies in the area, Childress states, are linked to advanced technologies under the water in the Bermuda Triangle that are still active. This goes to ancient mysteries, and perhaps ancient astronauts, about powerful Atlantean crystal technology developed being buried beneath the ocean floor when Atlantis sank into the sea due to cataclysmic events over 10,000 years ago.
This theory takes the viewer to the events of the Philadelphia Experiment in 1943 - rips in space-time in the Atlantic region - government secret projects and more.

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, Europe, and 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 hurricanes strike 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.
- 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 Gutierrez, 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 Sanchez 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...
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"; 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.
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.
- 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.
Methane gas can also crash planes. The less dense air causes planes to lose lift. Also, the altimeter of planes (the instrument that measures the altitude) functions on the density of air. Because methane is less dense, the altimeter assumes the plane is climbing. Planes at night or in the clouds, where they can't see the ground, assume that they are climbing and dive, causing them to crash. Also, methane in the engine throws off the mix of fuel and air. Aircraft engines burn hydrocarbons (gasoline or jet fuel) with oxygen provided by the air. When the ambient oxygen levels drop, combustion can stop, and the engine stalls. All of these effects of methane gas have been shown experimentally.
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.
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. 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.
Research has shown that freak waves up to 30 m (100 feet) tall, capable of sinking the largest ships within moments, can and do happen. Although these are very rare, in some areas ocean currents mean they happen more often than the norm. Such waves have now been hypothesized as a cause for many unexplained shipping losses over the years.
The book was a best seller, and many interested readers offered theories to explain the nature of the disappearances. The list includes natural storms, transportation by extraterrestrial technology, high-traffic volumes (and correspondingly high accident rates), a "temporal hole," the lost Atlantis empire from the bottom of the ocean, and other natural and supernatural causes.
The Triangle's location in the Caribbean makes it subject to unpredictable weather patterns. This takes us to Earth changes and the excalation of intense hurricanes in 2005 with more to come in the years ahead.
These weather extremes prey on inexperienced navigators and smaller boats and planes. Water spouts, sudden electrical and thunder storms, and the like, can cause havoc in the area. The Gulf Stream can also be brutal in that region and perhaps has swept away evidence of natural disasters.
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.
Other writers attribute the events to UFOs. This idea was used by Steven Spielberg for his film Close Encounters of the Third Kind, which features the lost Flight 19 as alien abductees.
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.
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 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 Taylor and the other pilots of Flight 19 do not indicate magnetic problems.
On December 5th, 1945, five Avenger torpedo bombers lifted into the air from the Navel Air Station at Fort Lauderdale, Florida, at 2:10 in the afternoon. It was a routine practice mission and the flight was composed of all students except for the Commander, a Lt. Charles Taylor.
The mission called for Taylor and his group of 13 men to fly due east 56 miles to Hens and Chicken Shoals to conduct practice bombing runs. When they had completed that objective, the flight plan called for them to fly an additional 67 miles east, then turn north for 73 miles and finally straight back to base, a distance of 120 miles. This course would take them on a triangular path over the sea.
About an hour and a half after the flight had left, a Lt. Robert Cox picked up a radio transmission from Taylor. Taylor indicated that his compasses were not working, but he believed himself to be somewhere over the Florida Keys (the Keys are a long chain of islands south of the Florida mainland). Cox urged him to fly north, toward Miami, if Taylor was sure the flight was over the Keys.
Planes today have a number of ways that they can check their current position including listening to a set of GPS (Global Positioning Satellites) in orbit around the Earth. It is almost impossible for a pilot to get lost if he has the right equipment and uses it properly.
In 1945, though, planes flying over water had to depend on knowing their starting point, how long and fast they had flown, and in what direction. If a pilot made a mistake with any of these figures, he was lost. Over the ocean there were no landmarks to set him right.
Apparently Taylor had become confused at some point in the flight. He was an experienced pilot, but hadn't spent a lot of time flying east toward the Bahamas which was where he was going on that day. For some reason Taylor apparently thought the flight had started out in the wrong direction and had headed south toward the Florida Keys, instead of east. This thought was to color his decisions throughout the rest of the flight with deadly results.
The more Taylor took his flight north to try to get out of the Keys, the further out to sea the Avengers actually traveled. As time went on, snatches of transmissions were picked up on the mainland indicating the other Flight 19 pilots were trying to get Taylor to change course. "If we would just fly west," one student told another, "we would get home." He was right.
By 4:45 P.M. it was obvious to the people on the ground that Taylor was hopelessly lost. He was urged to turn control of the flight over to one of his students, but apparently he didn't. As it grew dark, communications deteriorated. From the few words that did get through it was apparent Taylor was still flying north and east, the wrong directions.
At 5:50 P.M. the ComGulf Sea Frontier Evaluation Center managed get a fix on Flight 19's weakening signals. It was apparently east of New Smyrna Beach, Florida. By then communications were so poor that this information could not be passed to the lost planes.
At 6:20 a Dumbo Flying Boat was dispatched to try and find Flight 19 and guide it back. Within the hour two more planes, Martin Mariners, joined the search. Hope was rapidly fading for Flight 19 by then. The weather was getting rough and the Avengers were very low on fuel.
The two Martin Mariners were supposed to rendezvous at the search zone. The second one, designated Training 49, never showed up.
The last transmission from Flight 19 was heard at 7:04 P.M. Planes searched the area through the night and the next day. There was no sign of the Avengers.
What happened to the missing Martin Mariner? The crew of the SS Gaines Mill observed an explosion over the water shortly after the Mariner had taken off. They headed toward the site and there they saw what looked like oil and airplane debris floating on the surface. None of it was recovered because of the bad weather, but there seems little doubt this was the remains of the Mariner. The plane had a reputation as being a 'flying bomb' which would burst into flame from even a single, small spark. Speculation is that one of 22 men on board, unaware that the unpressurized cabin contained gas fumes, lit a cigarette, causing the explosion.
So how did this tragedy turn into a Bermuda Triangle mystery? The Navy's original investigation concluded the accident had been caused by Taylor's confusion. Taylor's mother refused to accept that and finally got the Navy to change the report to read that the disaster was for "causes or reasons unknown." This may have spared the woman's feelings, but blurred the actual facts.
The saga of Flight 19 is probably the most repeated story about the Bermuda Triangle. The planes, and their pilots, even found their way into the science fiction film classic, 'Close Encounters of the Third Kind.'
Where is Flight 19 now? In 1991 five Avengers were found in 600 feet of water off the coast of Florida by the salvage ship Deep Sea. Examination of the planes showed that they were not Flight 19, however, so the final resting place of the planes, and their crews is still the Bermuda Triangle's secret.
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 (610 m), 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.

There are numerous stories of the supposed appearance of strange creatures, unexplained vanishings, time standing still, slowing to a crawl, or speeding up, or other weird happenings.
One well-documented and well-known case includes that of Captain George R. Donner, who commanded the Great Lakes freighter O.M. McFarland. While on a journey back from Erie, Pennsylvania after picking up 9,800 tons of coal, the ship made course westward through the lakes. It was slow going due to late-spring ice floes, but the ship was making steady progress toward its destination, Port Washington, Wisconsin, when Donner disappeared.
On the night of April 28, 1937, the captain took to his cabin, with instructions to be awakened as the ship drew near to port. About three hours later, with Port Washington growing close, the second mate appeared at the captain's cabin, prepared to awake him, but found no one. He and the crew searched the ship, but the captain was nowhere to be seen. The mate reported that the cabin door was locked from the inside, adding to the mystery of the triangle. Reportedly, the ship was in the dead center of the triangle when the captain disappeared.
Another disappearance took place on June 23, 1950, and involved a Northwest Airlines DC-4 aircraft carrying fifty-five passengers and three crew members. This flight 2501 had departed from New York City and was due to land at Minneapolis. The last radio contact recorded with the plane was that it was 3,500 feet over Battle Creek, Michigan and was going to change its course to a northwesterly path over Lake Michigan, due to bad weather near Chicago. After this, the plane was never seen again, nor were the occupants. Even after an extensive search by the Coast Guard, only a blanket with the airline's logo was found. Once again, the aircraft was in the center of the supposed triangle when it disappeared.
