As early as the 1940s, unidentified flying objects appeared in the sky of the United States, and some of them looked like elliptical disks. Subsequently, in 1952, the United States established a research program dedicated to the study of these UFOs, the "Blue Book Project", and the first head of the Blue Book Project, Edward Rupert, officially invented the term "ufo", a program that lasted until 1970. Throughout the program, the researchers collected a total of 12,618 reports of UFO sightings. Of the tens of thousands of UFO sightings, only about 6% (701) of UFO sightings were identified as unexplained sightings, and most of the remaining sightings were generally natural phenomena or man-made flying objects.

Although humans have been studying UFOs for decades, collecting numerous reports of sightings and taking a large number of photographs, the truth about some UFOs has not yet been found. Since the truth of the UFO is not fully confirmed, it feels full of mystery, but when witnesses see some strange phenomena, it is easy to associate some strange flying phenomena with the so-called UFOs. Now there are UFOs in South Korea again, and this time the UFOs that appear are flying in formations.
According to a report on August 2, 2021, a man was sitting in front of his home smoking a cigarette in Jeonju City, North Jeolla Province, South Korea, when several unidentified glowing balls suddenly appeared in the night sky, these unidentified light balls flew in formation, and then the witness took out his mobile phone to capture the group of UFOs. From the shared picture, we can see that there are 3 unidentified objects that emit dazzling light at the beginning, and then these unidentified objects split into 6 unidentified luminous balls and disappear instantly, and the whole process lasts about 4 seconds.
For this phenomenon, experts from the South Korean UFO Investigation and Analysis Center believe that the unknown object in the picture is not a drone, laser, lens flare, etc., but a ufo. Moreover, these UFO formations were flying at hypersonic speeds at that time, that is, they flew at a speed of more than 5 times the speed of sound.
Although I have photographed these UFOs, seen the light emitted by these UFO, and even seen their splitting, it is impossible to see the details of these UFOs clearly. On the one hand, it was night, and on the other hand, the distance between the UFO and the witnesses was relatively far, and it was difficult to capture a clear picture.
As we mentioned above, most UFO sightings are just natural phenomena, artificial vehicles, etc., only a small number of UFO sightings can not be explained, those unexplained UFOs really exist? If there are UFOs that cannot be explained, where could they come from?
Looking back at history, we will find that there have indeed been some mysterious and inexplicable UFO sightings in history. For example, during the Falcon Lake incident on May 20, 1967, Canadian geologist Stefan Michalak saw two UFOs in the sky at Falcon Lake, one of which landed about 50 meters away from him, and the other flew westward.
When Stefan Miharak approached the UFO, it was vaguely suspected that he heard a voice talking inside the UFO, so he shouted at the UFO in multiple languages, but there was no response. Through the UFO's door, he also saw that the UFO had lights and control panels inside, and then the UFO closed the door and spun away, burning his abdomen with hot air from the engine. More than a month later, staff collected soil samples at the site and found that they contained reflective substances. Because cameras were not as ubiquitous as they are now, Stefan Miharak did not take videos or photographs of UFOs, but he drew a sketch of the UFO by hand.
If there really are such unexplained UFOs on Earth, where do they come from? So far, we have not seen any news of the interception of UFOs or the wreckage of UFOs, nor do we know what these mysterious UFOs are. However, there are some theories that these mysterious UFOs may be vehicles from alien planets.
The reason for this view is that some UFOs have super flying capabilities, such as the instantaneous disappearance of the UFO formation that appeared in the Korean region after flying at hypersonic speed, which is something that our current human technology cannot achieve, which means that if these UFOs are real, then they should be from the hands of intelligent beings who are more advanced than us humans. If there is intelligent life that is higher than our human beings, it can only come from an alien planet, after all, we humans are the highest level of intelligent life known on Earth.
Of course, the UFO formation that appeared in the Korean region this time does not rule out that it is only meteors, because it has just arrived in the Perseid meteor shower. When these meteoroids enter the Earth's atmosphere at a very fast speed, they will burn violently in the atmosphere and emit dazzling light, and during the combustion process, they will decompose due to uneven heating, and finally disappear into the sky. South Korea's disappearance after the 3 UFOs turned into 6 UFOs this time still has many similarities with the situation of those raging fireballs.
