We have selected ten most mysterious events in the history. Some have proper explanations for the myths but some haven’t.

1. Causes of Hindenburg's hot air balloon disaster

The crash in 1937 ended the era of hot air balloons. The legendary hot air balloon named after the German President under Hitler regime, Hindenburg, caught fire before landing in Lakehurst, New Jersey (USA). 35 people were killed out of a total of 97 people on board. It is known that before the fire, the Hindenburg intended to land to avoid a thunderstorm, but tragedy happened.

It was not until 2013 that the official cause of the accident was officially announced. US scientists have just concluded that the cause of this legendary hot air balloon's accident is static electricity. Experts have assumed that the ship flew into a charged cloud, leading to a fire and explosion.

Around 524 BC, King Cambyses' army of 50,000 men was ordered to advance towards Thebes but disappeared without a trace. Many rumors spread that this army was buried in a desert sandstorm. The real cause was buried for centuries.

However, the truth became clear when Egyptologist Olaf Kaper presented his statement. He said that as early as the 19th century people began to search for this army. It is hard to believe that such a large army disappeared without a trace.

Olaf Kaper believed that the Persian army on its way to the army was attacked by rebels led by Petubastis III. Next Petubastis conquered Egypt and became Pharaoh. Darius I, king of Persia, ended the reign of Petubastis, and to save the reputation of King Cambyses, he announced that an army of 50,000 men that year had been lost in the desert.

3. The Disappearance of the Nazca Civilization

The Nazca civilization has been a debate among scientists for many years. Their disappearance in the years 500 AD and the huge drawings left on the rocky plateaus are always a secret.

Today scientists prove that the Nazca self-destructed civilization suffered from the effects of El Nino and deforestation, leading to serious food shortages.

The Nazca people carved out a civilisation in southern Peru's arid valleys long before the Inca empire. They are best known for the Nazca lines: vast, intricate drawings etched on the desert floor, possibly sacred pathways. In addition to sophisticated pottery and textiles, the Nazca amassed one of South America's biggest collection of human trophy heads. The skulls had a hole drilled into the forehead. Academics disagree over whether the heads were of distant enemies killed in battle or sacrificial victims from closer to home.

4. Why was the ancient city of Palmyra built in the desert?

Palmyra is one of the famous ancient cities with a population of up to 100,000 people. How can Palmyra survive in a desert with such harsh climate?

Research shows that this area is not actually a desert, but an arid steppe with underground grass beds that keep rainwater underground. Rainwater from there flows into creeks and rivers, which the Arabs call "wadi" (oasis). Residents of the ancient city of Palmyra and many nearby villages have stored rainwater in dams and reservoirs for livestock and farming, ensuring a stable supply of food, and preventing disasters.

5. Where is Cleopatra’s tomb?

Ancient writers claim that Cleopatra VII and her lover, Mark Antony, were buried together in a tomb after their deaths in 30 B.C. The writer Plutarch (A.D. 45 to 120) wrote that the tomb was located near a temple of Isis, an ancient Egyptian goddess, and was a "lofty and beautiful" monument containing treasures made of gold, silver, emeralds, pearls, ebony and ivory.

The location of the tomb remains a mystery. In 2010, Zahi Hawass, Egypt's former antiquities minister, conducted excavations at a site near Alexandria now called Taposiris Magna, which contains a number of tombs dating to the era when Cleopatra VII ruled Egypt. While many interesting archaeological discoveries were made, Cleopatra VII's tomb was not among them, Hawass reported in a series of news releases. Archaeologists have noted that even if Cleopatra's tomb does survive to this day, it may be heavily plundered and unidentifiable.

6. Crocodile appeared in boat sinking

On 30 July 1915, after the U-28 sunk the British steamer Iberian, an explosion occurred in which, along with the debris, a creature resembling a gigantic crocodile was seen, which quickly disappeared from sight.

SM U-28 was a Type U 27 U-boat that served in the First World War. It was commissioned into the Imperial German Navy on 26 June 1914, with Freiherr Georg-Günther von Forstner in command. On 30 July 1915, Freiherr von Forstner reported a mysterious event after the U-28 sunk the British steamer Iberian. According to the commander: “The wreckage remained beneath the water for approximately twenty-five seconds, at a depth that was clearly impossible to assess, when suddenly there was a violent explosion which shot pieces of debris — among them a gigantic aquatic animal — out of the water to a height of approximately 80 feet.”

This creature was witnessed by the commander, the chief engineer, the navigator, and the helmsman. The commander reported that he couldn’t identify the creature, but he said that it resembled a crocodile. It was about 60 feet long, with four limbs resembling large webbed feet, a long, pointed tail, and a head which also tapered to a point. No photograph of the creature was taken as the animal sank out of sight after ten or fifteen seconds.

In 1994, Oakville, WA experienced a rainstorm in which gelatinous blobs fell onto a farm. The blobs were examined and found to contain human white blood cells, but they did not contain nuclei, which is something human white cells do have.

In order to identify the blobs, Barclift contacted his mother’s doctor, Dr. David Litle. Dr. Litle ran some tests at the hospital and reported that the blobs contained human white blood cells. When the blobs were examined by Washington State Department of Ecology’s hazardous materials spill response unit, they found that the blobs contained cells that lacked nuclei. But human white blood cells contain nuclei, so they were not a byproduct of a human body. Many theories have been presented to explain the appearance of the blobs, but none of them have proved to be correct.

8. Mysterious human feet on the beach

On August 20, 2007, a girl from Washington was visiting Jedediah Island in British Columbia, Canada. She found a size 12 Adidas shoe along the shore and picked it up. After opening the sock she found a man’s right foot in it. Upon examination, it was revealed that the kind of white-and-blue-mesh running shoe was produced in 2003 and distributed mainly in India. The foot was identified as those of a missing man suffering from depression.

Since then, a number of detached human feet have been discovered on the coasts of the Salish Sea in British Columbia, Canada, and Washington, USA. As of February 2012, only five feet of four people have been identified. The series of discoveries has been called “almost beyond explanation,” as no other body parts washed ashore along the coast.

9. The Thundercloud That Appears In Australia's Island Every Afternoon

From September to March, every year, a thundercloud named Hector forms nearly every afternoon on the Tiwi Islands in Australia. Hector, also known as Hector the Convector is known as one of the most consistent thunderstorms. It was named by a pilot during WWII and it still remains the center of many meteorological studies. Though many meteorologists have studied the interesting history of Hector, they have not come up with a valid explanation on why the thunderstorm keeps appearing.

10. A Mysterious "Dancing Plague" That Made People Dance To Their Death

In 1518, a “dancing plague” struck Strasbourg, Alsace. Also known as the “dance epidemic”, this weird condition took over 400 people’s bodies and made them dance without rest. Some of these people even died of heart attacks, exhaustion or strokes. It all started in July of 1518 when one woman named Mrs. Troffea started dancing uncontrollably in the middle of Strasbourg. She was later joined by 34 people and soon after the plague spread to around 400 people. At one point it would kill around 15 people a day.

Doctors and authorities realized this was not caused by supernatural causes and claimed this epidemic was due to “hot blood” but instead of treating the patients, doctors advised them to basically “dance it out” by building them a wooden stage. It is believed that the modern marathon runner would not be able to survive this type of intense workout. To this day scientists are not quite sure what caused this terrible epidemic, it might have been due to food poisoning caused by the toxic products of ergot fungi or it might have been a case of mass psychogenic illness.
