A wave of observations UFO an unprecedented event was crowned in these years. In the spring of 1961, a falling object caught a huge piece of the bank and slid part of the soil into a water reservoir, which the locals call Lake Korb. This is an unofficial name, in fact Lake Korb is an insignificant part of Lake Onega. There used to be a remote village of Entino, but the people abandoned it and now only a few dilapidated houses by the water remain.

UFOs and Lake Korb

At 9 o'clock in the morning, on April 27, 1961, forester V. Borsky, who had spent the night about 7 km from the lake, was walking along the shore of the lake. On the morning of April 28, he was returning to this place. Passing by the same bank where he had walked yesterday, Borsky suddenly saw a huge freshly dug pit that had not been there yesterday. The length of the pit was about 27 m, its width was about 15 m and its depth was about 3 m. One end of the pit almost touched the water, and in its extension was a huge opening, driven into the ice on the lake. Borsky stared blankly at the scene of the incident and hurried to inform everyone about it. He walked all day to the nearest game house, and from there at night to the town, from where a telegram could be sent to the district headquarters.

A week later, on May 2, a group of military and civilian specialists arrived from Leningrad. At first, experts believed that an incomprehensible explosion had occurred in the taiga, so the group's goal was to determine its causes and nature. Among those who came to Lake Korb was, in particular, a KGB agent with the characteristic surname Stukov, engineers and the future military journalist Viktor Ivanovich Demidov. More than once, during this time, I described these events and slightly changed the names of the characters (in my presentation, for example, I changed the name Borsky to Brodsky):

“We saw a large cavity, buried in a huge hole in the ice. In it were sparse torn pieces of ice. Next was smooth ice ... I went down into the pit, I saw neither spring nor underground water. Nothing to attract attention. The access to the water reservoir was considerably narrowed. The water itself bore traces of something heavy; the sod here was scattered to the sides, the bottom was smoothed a little. The ice on the lake was smooth, no cracks, no soil on it. Hmm, maybe she was fired… maybe start with this? In principle, such an explosion could be possible… But where are its remains?'

Diver Alexandr Tikhonov descended to the bottom but did not find any shell or missile fragments. He said:

“The bottom near the pit is covered with discarded soil and clumps of frozen debris. It is obvious why there is little floating ice in the pit! He sank down. The speed of the disaster did not allow the ice to disperse to the surface. The entire mass of discarded earth lies in a relatively narrow and long section. To the right and left of her the bottom is clear and flat.'

Emerald green color

At the bottom was a 20-meter-long path, ending in a 1,5-meter-high earthen mound. It was as if a pipe-shaped object moved along the bottom, pushing the ground in front of it, and then stopped and flew up. Beyond the edge of the hole in the ice was a normal clean bottom. As the diver ascended to the surface, he accidentally overturned one of the floating bushes. This caused the astonishment of all present when they saw that the inverted piece of ice was colored a bright emerald green at the bottom, half the thickness of the ice cap. The engineers overturned several floating bushes, and they were all the same bright, emerald green color.

They separated a piece of ice from the untouched area and it was normal ice, normal color. When the green ice (albeit already in a melted state) was delivered to the laboratory, the experts who performed the analysis concluded: "The elements detected in the melted ice do not provide the possibility to explain the green color reported by the members of the expedition". But after all - all members of the expedition saw this coloring with their own eyes!

According to the divers, the amount of soil found at the bottom of the lake was less than the amount that could have been thrown out of the pit. And around the hole in the ice, at the bottom and on the ice around, there was no soil, nor around the pit...

“We estimated that this thing dug into the ground at a colossal speed, scooped up about a thousand m3 of frozen earth from the bank, moved along the bottom about 20 m, sank to a depth of 5 m underwater and then flew vertically into the sky ... it could only happen in this way," Demidov wrote. “Otherwise, the body would have broken the ice in the lake over a large area and left traces on it ... but the edge of the ice was completely clean! No, it was something that is not very obvious.'

The engineers had a metal detector with them for the survey. They found that in the pit, next to it and under the water, the pointer moved more often than in the surrounding area, but even when they dug or sifted the soil with their hands, they did not find even the smallest metal particles. Only later did it become clear that the balls floating on the water were composed of some kind of metal alloy!

Strange noise

The commissioner of the district police department found that on the night of April 27-28, none of the residents of the nearby village saw or heard anything. But many claimed that two days after this event, from 2 to 4 in the morning, a loud intermittent noise, similar to the hum of aircraft engines being tested, was heard from the lake. "It stopped," said one of the villagers, "but then it started again...".

The army, having studied all the collected materials, compiled a report on the results of the inspection of the place of the fall of the unknown object. This unique document was cited in FJ Zigel's manuscript, but omitted all names and the exact location of the incident: “The place of the fall is the northern shore … 40 meters from the buildings of the former village. At this point there is a steep bank, with a slope of about 60 degrees. The point of impact of the object was located about 10-12 m from the shore. At the time of the inspection, the lake was covered with monolithic ice 40 cm thick. The water depth at the point of impact on the broken ice edges was from 0,1 to 5 m. The object was larger than 1,2 m in diameter.

As a result of the fall of the object, the bank was damaged, which has a geometrically irregular shape with rough edges... The bottom of the pit is shallow, flat with a slope of 10 degrees. At the exit to the water's edge and behind it, two filled strips of soil are recognizable, up to a distance of 5,5 m. On the right (western) edge of the pit, there is a faintly distinguishable excavated strip that leads to the bottom of the lake and has the shape of a cone with a maximum width of 40 cm , at the bottom of the lake opens into a flat, deep strip 20 cm wide. No regular tracks were found at the bottom of the pit.

The soil throw and also the crater outside the edge of the pit are not visible. A large amount of soil is located at the bottom of the hole in the ice … There are no thrown pieces of soil or cracks beyond the edge of the hole in the ice. Temperature effects at the point of impact of the object were not detected. There are stones and slate tiles in the deepest part of the riverbed, which break into individual plates upon impact. Stones outside the pit and on its edge do not have such properties. No stones with melted edges were found here...
Some pieces of ice in the hole have acquired an intense green color (such as chromium oxides). The coloring was uniform, straight. In one piece of ice from the uncolored part, an iridescent color with a radius of up to 2 cm was observed. There were no visible cracks at this location. When the ice melted, the green mass precipitated as elongated flakes.

Chemical analysis of the sample

Qualitative chemical analysis of this sample, conducted by the Department of Analytical Chemistry of the Leningrad Institute of Technology, named after the Lenin Soviet, showed that small amounts of silicon, magnesium, iron, aluminum, sodium, calcium, barium and boron were found in the water filtered from the solution. In the mineral precipitate after calcination of the acid extract, silicon, magnesium, titanium and sodium were found as the main elements. Calcium, aluminum and iron were detected as impurities. The precipitate had a metallic luster. Many organic substances of unknown composition have been found in water and sediments. Chemical analysis of the uniform coloring of the ice did not provide an explanation...

Along the edge of the water and in it, floating grains of black color, regular geometric shape, surrounded by foam appeared. When examined under a microscope, a characteristic metallic luster was visible, inside the grains were hollow, fragile and easy to spread. When calcined, they changed color without changing shape and were extremely resistant to acids. When examined in the infrared spectrum, no organic substances were detected in them. According to the experts' conclusion, the balls were apparently considered to be formations of artificial origin... All samples were tested for the presence of radioactive or toxic substances. No such specific substances were found in the samples.

Three years later, Viktor Demidov spoke briefly about what happened in the newspaper of the Leningrad Military Region "On Guard of the Fatherland", without mentioning the exact location or the names of the eyewitnesses. Only when he did did Viktor give a detailed account of the incident in his book: "We were the last to leave."

Many years later he recalled, “Of course it didn't make it into the publication (location, names, etc.). The big bosses sent us to the lake and took care of the background... They quickly helped us get to a renowned laboratory with specialists in meteorites, spheres, lightning, landslides, caves and all kinds of secret matters ... and no one said - it's this or that. Doctors (they were led by the relevant member of the Academy of Sciences of the USSR, VB Aleshkovsky) generally wrote that the elements determined in the melted ice could not cause the green color that the members of the expedition stated ... About the metal balls, they said that they were made of rare metals, acid-resistant, heat-resistant and … they are apparently not of natural origin…

Let me ask. So what are they made of? Professor Aleshkovsky was careful not to specify it, but he told me confidentially - I have not seen such a combination of elements and I cannot imagine the technology that could create them ... The army did not contribute anything in this case. When the famous air general, PI Kožedub, as they say, simply threw an explanation at his pilots, (it was in my presence, I suspect they coughed it up), in our headquarters they also coughed it up. The report I drafted didn't go anywhere either. It had nothing to do with official scientific circles. Even cosmonaut GS Titov could not arouse interest in this incident on Lake Korb.

As the vice-president of the Academy of Sciences, M. Lavrentěv, once told me:

"No one was concerned with the suspected holes - all scientists are focused on their narrow field of research... How many famous sensational reports about UFOs have ended like this..."
