More than an hour later.

Dawn one returned and landed on Yanhuang island.

The test flight was a complete success.

A grand celebration was held on the island.

Cameron now understood why the other side had to train pilots.

Just now they wandered around over Florida. The Americans were completely unaware of it. In the "stealth" mechanism, dawn is far better than the Americans!

If they had just carried a bomb, they might have made history by pressing a button.

"Mr. Chen, the birth of dawn, I think it needs to be kept secret at present. Don\'t leak the news, otherwise you may be in danger."

Carmen reminded me with the bottle.

Every man is innocent and bears his sin.

He himself is a deep victim.

Because of Xingyan, his father was killed. He was almost forced to drink for the rest of his life.

You know, it\'s just a star rock.

The technology represented by dawn can directly threaten the national defense security of every country in the world, including the United States, the first military power. If they know the existence of this weapon, they will have trouble sleeping and eating and will absolutely take measures.

At that time, even with ward group as a backer, I\'m afraid it wouldn\'t help.

After all, no matter how powerful a chaebol is, its power is limited. It is impossible to oppose a country or even the whole world.

"I understand."

Chen Liang nodded.

And now.

Florida National Air Defense Center.

The successive phone calls and the news spread through various channels made these security personnel feel heavy and like a great enemy.

Just now, many citizens claimed to have seen UFOs in the sky, and some even heard sounds.

There are also many related videos on the Internet.

Don\'t say why stealth fighters can be seen by human eyes.

The so-called "stealth" of fighters is only for radar detectors.

As long as the radar can\'t find it, it will succeed.

After all, when you can see a fighter in the air with your naked eye, it\'s all over.

"What is this? UFO?"

On the big screen.

A video shot by a witness is being released.

It can be seen that in the high altitude, there is indeed a black thing passing through the high altitude at a very fast speed, but because of the height, I can\'t see what it is. I only see a fuzzy black spot, which is really like an unidentified aircraft.

Many people on the Internet say it may be birds, but this statement is really funny in the eyes of these professional security personnel.

The flying altitude of UFO should be more than 20000 meters. What bird can fly so high?

"What are the detection results of radar observation signals?"

The person in charge asked seriously.

There are unidentified flying objects passing in the airspace, which is not trivial. It is related to national security. As soon as the news came out, it immediately attracted the attention of many important departments and asked them to thoroughly investigate the truth.

"The radar... Didn\'t respond and didn\'t catch the signal of any object entering."

This result is also expected. If the radar finds something abnormal, they won\'t wait until rumors come out of the outside world to know the news.

"Head, the two planes to intercept have not found the target. It may have left."

"Damn it!"

The person in charge of the air defense center beat the table with an ugly expression.

He was invaded by a UFO, unaware of it, and didn\'t even know what it was afterwards. He could not escape a crime of dereliction of duty.

"Boss, do I think it\'s a UFO?"

It\'s not the first time that they Americans have encountered this situation.

"Head, the infrared detector has weak signal traces."

The person in charge of the air defense center was shocked, "say!"

"The UFO entered Florida at 2:43 p.m., circled for about a minute, and then left."

"In which direction did it come in and in which direction did it leave?"

"I don\'t know. The signal is very weak and the traces left are intermittent, but it can be judged that it is fast and should break through the speed of sound."

Because people have eyes, they can perceive light, see things, hear things because they have ears, feel the wind when the wind blows, and have these devices that can receive information, so people can perceive the world and know their existence.

However, if a certain perception ability is missing, some information receiving ability will be lost. For example, you are blind. When a lightning bolt occurs, you can\'t see it at that time, but it exists. A few seconds later, when the thunder comes and you hear it, you know it has flashed.

Stealth fighters are like lightning. Just because you can\'t "see" at that time doesn\'t mean you can\'t "hear" later.

Because it is a stealth aircraft, ordinary radar can\'t find it, but there are other ways to detect it except radar. Only when it is found, it has flown away.

Stealth fighters can not really "come without shadow and go without trace". The real value of stealth aircraft is to make an information difference and time difference.

"Head, it should be a UFO. Now there is no supersonic stealth fighter in the world, even our B2 can\'t do it."

The stealth technology of fighter aircraft is more accurate and should be called "low detectability technology". Fighter aircraft can only be stealth by changing the aerodynamic layout and shape of the aircraft to minimize the scattering area of radar; second, reduce the infrared radiation of fighter aircraft.

For the fighter, the threat mainly comes from radar detection devices and infrared detection devices. When the fighter is flying, its airborne radar, communication equipment and related components are in working state, it will emit electromagnetic waves, and its surface will also reflect electromagnetic waves. While the fighter\'s engine will also generate heat and radiate infrared rays during operation, so as to make the fighter and its surroundings The function of radar is to capture these signals and find the target.

According to the working principle of radar, what stealth fighters need to do is to try to reduce their reflection of external electromagnetic waves, light waves and infrared rays as much as possible through various ways, so as to make it difficult to distinguish the fighter itself from the background, so as to achieve the purpose of concealing itself, that is, the so-called stealth technology.

But at the same time, we should also understand that although the stealth fighter is invisible, it is not invisible. In the Kosovo war, the fry locked the f117a stealth fighter with meter wave radar and shot it down at one fell swoop. This is also the first battlefield defeat since the advent of the stealth fighter!

"There are only a few countries in the world that have stealth fighters. We have filed several of their stealth fighters. As long as we come in, we will definitely find them and shoot them down at the first time."

UFO theory is becoming more and more popular.

In fact, within the official of the United States, they all believe that there are aliens in the universe.

So after encountering incomprehensible technology, they subconsciously push on aliens.

After all, they are the best in the world in the research of stealth fighters, and no one can surpass them.
