What does the frequent UFO display in China’s airspace say?

On November 2, 1999, at 16:45 and on November 9, 16:45, "UFOs" passed by each other twice. A newspaper in Shanghai reported: "UFOs visited Shanghai again!" Exactly 7 days apart. The UFO that appeared over Shanghai last Thursday "appeared" again on the 9th. This time, it used the same shape, the same time, and the same orbit. After "wandering" over Shanghai for more than ten minutes, it mysteriously disappeared again.

According to Ms. Yang, an eyewitness standing in the Hongqiao area, at about 4:40 pm on the 9th, a flying object appeared in the southwest sky, which was the same as the one that appeared last Thursday. Golden color. The head is very bright, with a white tail trailing behind it, much shorter than an airplane, like a swallow's tail, which crosses and then spreads out. This UFO flew in the sky at a constant speed. The whole process was similar to the last time, within about ten minutes.

At 4:45, Ms. Hu, an eyewitness on Xinzha Road, said: Around 5 pm the day before yesterday, she saw the same flying object as last Thursday, flying at a constant speed from south to north, and the overall shape was golden. Yellow, like "Halley's Comet". Colleagues who were with Ms. Hu all shouted, "I saw a broom star."

Wang Xiankun of the Shanghai Observatory told reporters: The UFO that appeared the day before yesterday was 7 days apart from the first appearance last Thursday. There is a periodicity in time; secondly, the two appearances were at the same time. At around 5 p.m., the location, shape, color, and trajectory of the UFO were exactly the same twice, so a preliminary judgment could be made: it was an aircraft, and it was a man-made aircraft. It's not a cloud, it's not light, it's not an atmospheric phenomenon. The observatory can make precise judgments from the fixed orbit and shape of UFOs, and the answer will be revealed soon.

There are different opinions about the visit of "UFO" to Shanghai. It can be roughly divided into two categories: "academic school" and "people school". The "people's faction" insists that "visitors from outside" are observing Shanghai.

Just a beam of light

Most of the "academic" opinion is that this is an atmospheric phenomenon. When being interviewed by the media, Fu Qicheng, director of the Scientific Research Department of the Shanghai Observatory, said in a decisive tone: "Where did the UFO come from? It's just a beam of light."

According to Fu Qicheng's analysis, first, this "UFO" is not It may be a meteor. A meteor flashes in the sky for only a few seconds and cannot remain stationary in the sky for more than ten minutes. Secondly, it cannot be a fragment of an artificial satellite because it is similar to a meteorite. It flashes for a short time and cannot remain stationary. Thirdly, it cannot be stationary. It's impossible for a steel ball. The sun's rays on the balloon will indeed glow, but the ball is round and can only be seen as a dot in mid-air, while the "UFO" is a long strip; fourthly, it is also impossible Airplanes, because airplanes are in motion. From this, Fu Qi admitted that it was a meteorological phenomenon. He explained that it might be a ray of sunset that shot out from a very small cloud gap and slanted on the bottom of a cloud layer, showing an orange-red color. Because there was very little wind at the time, the clouds were moving slowly or even standing still.

Unidentified man-made objects

Zhang Jiacheng, chief forecaster of the Shanghai Central Meteorological Observatory, believes that if the "UFO" does turn and move as the witnesses said, it cannot be a cloud. Among the witnesses, professional Jiang Xiaoyuan said that the altitude of the horizon at that time was 60 degrees, and there were no clouds around. It was a clear blue sky. Therefore, the possibility that the "UFO" was a comet, a meteor, an airplane, or a cloud should be denied. He was inclined to believe that it was a comet, a meteor, an airplane, or a cloud. "Unidentified man-made object".

Special aircraft

After several days of dispute, the authoritative expert from the Purple Mountain Observatory of the Chinese Academy of Sciences said: "It is probably a special aircraft." This conclusion was reached based on Researcher Wang Sichao explained that there are 7 different types of luminous objects in the sky. According to the analysis of the existing data on the "UFO" visit to Shanghai this time, celestial bodies, high-altitude balloons, clouds, aircraft contrails, etc. can be basically ruled out. Wang Sichao clearly disagreed with the idea of ??"a beam of light". He said that at an altitude of nearly 10,000 meters, it is impossible for the clouds to remain basically unchanged for more than an hour.

News from the East China Air Traffic Control Bureau rules out the possibility of internship on new model aircraft.

UFO discovered in Guangdong on December 10, 1999

On December 10, a similar UFO appeared in the sky over Xinfeng County, Guangdong Province and was photographed.

At around 6:40 in the evening on the 10th, Liu Shaobo, publicity officer of the Party Committee Office of the Second Hydropower Bureau of Guangdong Province, discovered and photographed a UFO on the mountainous road from Xinfeng to Guangzhou. At that time, the UFO was moving slowly northwest in an arc shape, with two white tails ejected from its tail. According to Officer Liu, it took about 10 minutes from the beginning of shooting to the disappearance of the flying object.

Taiwan saw a UFO on December 12, 1999

On December 12, in the northern part of Taiwan Province, a local resident took a photo of a UFO. The photographer said that he saw something like a fireball streaking across the sky for about 5 minutes. This UFO is suspected to be the one that appeared in Shanghai a few days ago.

CCTV "caught" a UFO on December 12, 1999. At around 5 pm on December 12, two UFOs appeared in the sky southwest of Liucun Town, Changping District, Beijing. CCTV reporters successfully photographed these two UFOs.

These two flying objects are very similar to those that appeared in Shanghai recently. The two flying objects moved up and down slowly towards the south of the sky. About 20 minutes later, the flying object flew out of sight of the reporter. CCTV reported on the evening news program that evening.

Strong light passed over Chongqing on December 14, 1999

At 5:49 pm on December 14, 1999, on the roof of No. 68 Renhe Street, Daxigou, Chongqing The old man Feng Changren who was resting shouted excitedly, and a bright UFO flew over Chongqing.

Old man Feng Changren said that he and his wife were practicing calligraphy with their children on the open space on the roof when they suddenly felt a flash of light. He suddenly looked up and saw a strong light coming rapidly from the direction of Huangjiaoya. "Glancing" over, with a long tail. Mr. Feng called his grandson, wife and neighbors to watch. This bright light flew a little higher and faster than the planes we usually see. It quickly flew towards the north of Hong Kong and lasted for about two minutes. Because the time was too short, Mr. Feng did not have time to take photos of this "wonder".

After the reporter learned about it, he quickly contacted a certain department of the Air Force stationed in Chongqing. The department said that there was no abnormal reaction in the sky above Chongqing yesterday. The Municipal Meteorological Observatory also said that there were no abnormal changes in the weather yesterday.

UFO flew to Changchun on December 11, 1999

Following the discovery of a UFO in Shanghai, on the afternoon of December 11, Changchun citizens also discovered a UFO and captured it with a camera The entire process of the flying object from its appearance to its disappearance.

At 4 pm on December 11, Mr. Jiang, who was on the 5th floor of a residential building in Changchun, casually looked out the window. Suddenly, he found a luminous object in the sky southwest of his house, which was orange. . It was 4:07 pm. The sun had set and the clouds on the sky were pink. Mr. Jiang immediately turned on his digital camera to take pictures. In the first two minutes, the flying object moved slowly from top to bottom, with a bright light in the middle and a very beautiful orange tail. Next, the flying object flew parallel again, and for a moment, it almost stayed motionless in the air. At about 4:10 pm, another flying object appeared at the lower left of this flying object. The two flying objects crossed at an extremely slow speed. At about 4:18 pm, the two flying objects completely disappeared from Mr. Jiang’s sight.

The reporter learned from the local garrison that no flight internship was held that day. Mr. Wang, a citizen who also saw this strange phenomenon, said that the flying object's flight situation was very similar to the UFO discovered in Shanghai broadcast on TV.

UFO reappeared in Changchun on December 20, 1999

An unidentified flying object visited the sky above Changchun City three times on the afternoon of the 20th, causing citizens to stop and watch. It is reported that this is the second time a UFO has appeared over Changchun City since December 11.

According to eyewitnesses, at about 3:45 pm on December 20, an orange flying object suddenly appeared in the sky southwest of Changchun City, flying from southwest to northeast, and disappeared after a few minutes. About ten minutes later, the UFO flew back from the opposite direction. What was different from the last time was that this time the UFO looked particularly clear, with a round head and a particularly long tail. After flying for about a minute, it flew back from disappeared from people's sight. After about ten minutes, the "flying object" turned back three times. It was exactly the same as the second time. It disappeared shortly after it appeared.

UFOs reported in 1999

On the evening of June 22, an "unidentified flying white light" visited the Jiangcheng city of Wuhan, causing more than 700 large trees to break in half.

In the middle of the night on September 11, a citizen of Dalian City claimed to have witnessed four UFO-like UFOs, dark yellow in color, spinning in the clouds, and their speeds were 2 to 3 times faster than airplanes. .

At around 17:30 on November 23, several people at Shantou Airport witnessed a UFO (the shape could not be seen from the front) dragging a light yellow tail smoke about 10 meters long. It flew slowly from north to south and disappeared from the horizon at 17:45. The whole process took about 15 minutes.

At around 17:05 on December 2, an orange-red UFO appeared in the sky southwest of Shanghai.

At 17:20 on December 7, a UFO was discovered in the southwest of Xiamen Island, lasting about 15 minutes.

At about 4:30 pm on December 9, a UFO appeared over Dalian City. It was like a fireball, flat and long, flying from northwest to southwest, and from low to high. , turns orange and disappears after 10 minutes.

On the evening of December 9, the UFO visited Shanghai again. The time, location, shape, color, and trajectory were exactly the same as those that appeared seven days ago.

At 5 pm on December 11, a photographer in Wuchang took a photo of a UFO flying from southwest to east. In the photo, the UFO looked like a small white light strip. The sky is swimming.

At 4:07 pm on December 11, an orange luminous object appeared in the sky over Changchun City. At about 4:10, another flying object appeared at the lower left of the flying object, and the two flying objects crossed. Flying at extremely slow speed.

On January 7, 2000, the satellite captured a huge unknown luminous object

covering the Shandong Peninsula and the sea; the shape is elliptical, running northwest and southeast; it is geosynchronously stationary meteorological Satellites captured the real scene; it was hidden in large thick clouds that were difficult to reach with the naked eye.

At 6 pm on January 7, 2000, a major news came from the meteorological station of the Yantai Civil Aviation Station of Laishan Airport in Shandong Province: Engineers at the station were surprised to find in the meteorological satellite cloud image on the evening of the 5th that an explosion appeared over the Shandong Peninsula. Huge unknown luminous object.

According to the "Yantai Evening News" report, this is the first time such a strange phenomenon has been discovered since the launch of the Laishan Airport meteorological satellite system. According to reports: At 23:32 on January 5, engineers at the Laishan Airport Meteorological Observatory were receiving meteorological satellite cloud images taken by the Japanese geostationary meteorological satellite GMS-5 (the GMS-5 meteorological satellite is synchronous with the earth at an altitude of 20,000 meters above the ground). Operation, which specializes in taking weather cloud images of the Northern Hemisphere), discovered this huge unknown luminous object. The area covered by the luminous body is over the Shandong Peninsula and the southeastern sea, spanning 3 to 5 latitudes and longitudes. The center is located at 122 degrees east longitude and 36 degrees north latitude. It is oval-shaped and runs northwest and southeast.

After enlarging the image, it can be seen that the outside of the luminous body is bright white, and there are 3 to 5 layers of light green halo evenly from the inside to the outside. The two empty ends of the ellipse show combustion jets respectively. The shape of scattered matter.

According to the infrared cloud image, there is a large and thick cloud system over the Shandong Peninsula at this time. It can be inferred that because the unknown luminous objects are located above the clouds, people on earth cannot see them with the naked eye.

It is understood that the GMS-5 satellite takes a cloud image every hour, and then after half an hour of system processing, the information is sent to the satellite cloud image receiving devices on the earth, so at 23:32 Beijing time The luminous objects that appear on the cloud map are actually satellite photos taken around 23:00. At present, based on the existing technical conditions, we can only conclude that it is a huge unknown luminous object, and it may be in motion. It cannot be further determined whether it is an artificial object or something else.

There are two suspicious things about this unknown luminous object. First, the photo taken by the infrared system at the same location does not contain any objects or luminous objects, while the photo taken by the visible light system can be clearly seen. Relevant experts speculate that the external temperature of the luminous body can change with changes in air temperature. Second, the specific size is difficult to calculate. From satellite cloud images alone, the luminous body almost covers the entire Shandong Peninsula. Another possibility is that the luminous body is relatively close to the satellite lens.

According to reports, the weather station staff had previously seen a strange luminous object over the Shandong Peninsula, but it was not recorded at the time.

What are the UFOs that appear frequently? China Southern Airlines experts say they are elusive

What are the "UFOs" that frequently appeared in the skies over Beijing, Shanghai, Wuhan, Changchun and other places in late 1999? Various speculations have been triggered in the society. An aircraft expert from Nanjing University of Aeronautics and Astronautics said in an interview with reporters that this thing is 80% not an aircraft.

Yao Weixing, professor and doctoral supervisor of the Department of Aircraft of China Southern Airlines, said that from an aerodynamic perspective, it is difficult to hold up the claim that this "UFO" is an aircraft. First of all, in order for an aircraft to fly in the air, it must use a certain flight speed to form a lift that lifts itself into the air. However, judging from the video and eyewitness descriptions, the flying speed of this "UFO" is really slow and cannot generate Such a large lift; secondly, in the video and eyewitness descriptions, the "UFO" will still stay in the air in a static posture, while at this time the eruptions from its tail are rushing upward, which is also impossible in aerodynamics . Because the aircraft needs to be stationary in the air and start to generate a vertical downward force, then its power surface should be below and the ejection should also rush downward. In addition, this "UFO" will also fly slowly and rapidly in a very short period of time. From the perspective of physical acceleration, the aircraft absolutely cannot do this. Professor Yao believes that the so-called "UFO" is most likely a group of clouds under the slanting light of the setting sun and driven by the wind, which creates an illusion in the eyes of witnesses.

Professor Yao also said that the above reasons are all based on the current scope of human cognition, but if there is an extraterrestrial civilization that sends "extraterrestrial visitors" to the earth that are completely inconsistent with our power and operation methods, ”, which goes beyond our current understanding of aircraft.

Is this really an "extraterrestrial visitor"?

Experts are cautious about this. They believe that the visit of alien spacecraft to the earth is currently just a legend, and humans have not found evidence to prove the existence of extraterrestrial civilizations. Wang Sichao, a researcher at the Purple Mountain Observatory, and Miao Qihao, deputy director of the Shanghai Library, also expressed the same views to reporters. For now, neither man-made aircraft nor unverifiable extraterrestrial objects have posed a threat to mankind. Miao Qihao further expressed his appreciation for the media's truthful reporting of "UFOs".

The Shanghai Observatory promises that it will make an accurate judgment from the fixed orbit and shape of the "UFO", and the answer will be revealed in a short time.
