- For many decades, residents of the city of Taos in the USA have been hearing an unusual hum, the so-called Taos hum or Taos noise. This is an anomalous sound phenomenon in nature. The hum is similar to the movement of heavy equipment on the road, but there are no big roads in Taos. It is also strange that not all residents hear this noise, only about 2%, and visitors don’t hear it at all. Scientists tried to find out where the source of the incomprehensible hum was. However, they found nothing and referred to the power line. What kind of sounds they were and where they came from was unclear, and to this day the Taos hum remains not only unexplained but is also included in the Ten Unexplained Phenomena of the program "Unsolved Mysteries.
- On November 24, 1971, a Boeing 727 airliner was hijacked en route to Portland. A passenger named Dan Cooper sat in his seat 18C in Portland and, 8 minutes after takeoff, passed a note to the flight attendant. The note said that Cooper had a bomb in his briefcase and that the plane had been hijacked. The air pirate's demands were four parachutes and $200,000 in twenty-dollar bills. The flight attendant was shown a bomb, and it was decided to cooperate with Mr. Cooper. At 17:24 the plane landed in Portland. Cooper prudently asked to turn off the lights on the plane to prevent snipers from seeing him. The government satisfied the demands of the invader, and Cooper himself released the hostages except for one flight attendant, the board mechanic, and the pilots. At 19:40 the plane took off in the direction of Washington. After a while, Cooper sent the flight attendant to the cockpit and ordered her to remain there. At about 2:13 DB Cooper jumped from the plane. However, two more parachutes remained on the plane. Did the robber manage to land? What happened to him and where the money went did not become clear. In the 1980s, $6,000 from the series that were given to Cooper were identified. However, the fate of the rest of the money is unknown. Just as unknown is the fate of criminal 45 years after the hijacking, the FBI suspended the investigation of this case. To this day, DB Cooper is one of the most mystical figures of the last century.
- Ronga ronga or Koha rongo rongo - these are wooden tablets with the inscriptions of the inhabitants of Easter Island. The tablets were discovered in 1864 by the bishop Eiro. Shortly before this, many residents of Easter Island, including those capable of deciphering Koha o Rongo Rongo, were taken as slaves to Chile. In 1866, most of the tablets were destroyed, and only 25 of them have survived to this day. Deciphering this writing is almost impossible, and those capable of reading these signs are no longer left. Small amount of text, lack of context, and the mix of languages of the inhabitants of Easter Island - these are the main problems in deciphering the inscriptions. Many scientists have tried and are still trying to understand what is written on the wooden tablets. However, what is certain is that some of the information is related to the lunar calendar. So ronga ronga is another unsolved mystery of Easter Island along with statues. What if statues and tablets are somehow connected?
- On the Nazca plateau in southern Peru, there is a group of giant images of the so-called geoglyphs. About 30 drawings depict animals and people, 133,000 lines and stripes, as well as about 700 geographical figures are located on an area of 50 km. The drawings are quite large and you will see them from the ground; it is difficult to understand them from the ground. The meter-long Condor, Catfish, Spider, and Fifty Caliber are not visible so easily; they were discovered only in 1939 when the plane of the archaeologist Paul Kosaka flew over the plateau. Dating these geoglyphs is a complex matter; scientists only agree that they were created before the 10th century. Many researchers believe that their creators are the Nazca civilization, which existed until the 2nd century BC. The reasons for the creation of these truly grandiose geoglyphs are not completely clear. Many believe this is the worship of deities; others believe the Nazca geoglyphs are the most astronomical calendar. UFOlogists talk about the geoglyph as a landing site for alien ships. What is this actually unknown to anyone and the drawings were preserved only thanks to the semi-desert; they were dug half a meter deep since 1994. The geoglyphs are a UNESCO World Heritage Site, although they are incomprehensible to modern humanity.
- Caño Island and the Nicoya Peninsula off the Pacific coast of Costa Rica have their own secret on them. Stone balls, of which at least 300 were discovered. These balls are made of gabbro, limestone, or sandstone and they measure from an inch to 2 meters in cross-section. The largest of the balls weigh up to 16 tons. The dating of their creation varies from 200 BC to 1500 AD. The reason for the creation of these petrospheres is another unsolved riddle. There is an assumption that this is either a designation of luminaries or the boundaries between the lands of different tribes. How the tribes that built the balls achieved these perfect shapes is also a matter of dispute. Some suggest that they lay for a long time in the water, which allowed them to be so round. These artifacts were discovered only in the last century by workers when clearing areas for banana plantations. Many workers split and drilled stones, hoping there may be gold. However, the management of their company soon stopped vandalism. Since the 1940s, geologists and scientists of all stripes began to study the balls and took them to museums. These petrospheres stone balls of Costa Rica in their places - this is another mysterious chapter from the story of the disappeared tribes and another mystery that people will most likely never solve.

The case of lead masks - this is the story of two corpses found on Winn Hill near the city of Niteroi in Brazil on August 20, 1966. The name of the case was given to two lead masks found on the faces of the dead. Both corpses were lying on a bed of leaves, dressed in business suits and waterproof raincoats. Next to the bodies lay a notebook in which there was a note with approximately the following content: "16:30 be in a designated place 18:30 swallow the capsule and after which illegible words and the word mask." The dead were local radio engineering is interested in ufology. So one of the police versions was that they were killed by lightning or that they were experimented on and all their money was stolen. However, the first version was rejected by experts and the second version seemed too far-fetched. There were also versions that they were plunged into a trance or something else, a UFO is to blame for their death. However, the death of these people is still shrouded in darkness. Mysteries, see electrical shop number 10, all sorts of legends. Of course, everyone refers to a gas leak, some kind of explosion, an accident, but not. The story of the orange Medan ship begins in 1947 when two American ships received an SOS signal for help. A man who was a member of the crew of a Dutch ship, an orange Medan, a man screamed, everyone is dead and soon it will come for me, then after a strange noise, the sailor said I’m dead and the broadcast stopped. Having come to the aid of the ship in distress, American ships discovered the corpses of all crew members. And despite the fact that they died many hours ago, their body temperature was over 40°. When they tried to tow the ship, it caught fire and exploded, sinking to the bottom. And despite the story of both crews of American ships, many claim that the ship named Orange Medan simply did not, there was, however, there is evidence from several people that their relatives were hired on such a ship and there are even two photographs of this ship, however, neither the purpose of the voyage nor the cause of the disaster is known, how did the crew die. October 21, 1978, excellent flying weather plane from Rabin with a pilot named Frederic Valenti who has more than 50 hours of flying practice behind him. In the middle of the flight, the pilot contacts the base and asks if there are military aircraft flying near him, receiving a negative answer he began to talk about the fact that that big plane is flying over it as if it was starting some kind of game for 6 minutes while there is a dialogue between the pilot and the dispatcher, the connection is constantly lost and the pilot coughs more and more, and then in 1912 the connection with the pilot stops, the search teams sent to search for the plane, nothing they didn’t find anything other than an oil stain on the bass strait, and that stain was not the plane’s fuel; an interesting fact was the pilot’s last words that it was not an airplane. However, knowing about his passion for ufology, one can assume that this is all mind games, however, Australian ufologists consider this one of the most reliable evidence of contact of aliens with us is still not clear what happened to Valentich. However, among cynics, thoughts of suicide and faking death prevail Although the plane and pilot were never found. Canadian Oak Island hides many secrets, one of them - this is the possible discovery of untold riches in the so-called money mine. The history of the discovery of this mine is somewhat different: someone says that children aged about 16 years old stumbled upon it in 1975, someone says that an old sailor who drowned in 1805 spoke about the mine and treasures when his grandson found a map of the island from my grandfather and took it to my grandfather’s colleagues, who without hesitation promised to help. However, it burned down along with all the documents. The very next night, under the ashes, a deep mine was discovered, which many generations of treasure hunters began to dig up; they went deeper into the mine. However, despite the fact that 60 m had been dug, it was not possible to find the treasure, whether there were treasures there and whose they actually are still remains a mystery. However, interest in the money mine is fading away every day and brought only a few stories on a similar topic. Yes, a documentary series about the excavations of the mine on Oak Island. One of the most famous serial killers acted in London in the second half of 1888, the Whitechapel killer, aka Jack the Ripper, is one of the most famous names of a serial maniac. In addition, the maniac has many uncaught victims. However, the number ranges from 1 to 15, although only five victims of the Ripper are considered canonical; they were prostitutes whose throats he strangled and cut; an interesting feature of the criminal was that he was sure that he would not be caught; this is evidenced by the letters he wrote to the police; there were many letters received. However, only three were definitely sent by Jack the Ripper, by the way, the name appeared from the first letter; the most notable ones are considered the third letter, called from hell, delivered with half a kidney; the letter says that the second half was eaten by a maniac; there were many suspects in the case; however, it was known for sure about the surgical skills of the maniac; nevertheless, Jack also disappeared suddenly, how he appeared and it is still unknown who he was and why he disappeared. Did he die, did he go to prison, did he escape from London, all these theories apparently will remain theories without shedding any light on this mysterious killer.
