It's an amazing feeling to go through the sound barrier.

Before the speed of sound, the inside of the plane is very noisy, the sound of high-speed airflow, the sound of the engine, will come into the ears, although the headset in the flight cap is to reduce the noise, just like the tank soldier's hat, the noise has been reduced to a relatively small level, but the sound is still very loud, then once you have supersound, suddenly it seems to enter another realm, because you are walking in front of the sound, then at this time, in fact, the sound can not reach you.

The cabin became quiet in an instant, and as soon as you flew over supersonic speeds, you knew that it was the feeling.

At the same time, the scene in front of the nose of the aircraft is also spectacular, this milky white umbrella-shaped thing is the shock wave.

This is an air flow, it is a sub-interface formed by the rapid change of pressure and temperature, this shock wave is quite terrifying, and it is forbidden for fighters to fly at supersonic speed at low altitude, because this shock wave will bring terrible consequences to the ground.

For example, if this shock wave sweeps through the crowd and sweeps over the building, it may cause a perforation of the eardrum of the person, which will cause the entire glass to shatter.

The airspace of the test flight, looking for this deserted Gobi Desert, is for this purpose, and now, I have finally flown there!

Qin Feng could even hear the sound of his own breathing, and Qin Feng's brain was also very quiet.

He looked at the dashboard in front of him, and when the height was three hundred, he began to pull the operating lever, and his body was thrown in pain, and the fighter roared towards the ground at supersonic speed, and if he couldn't pull it up, then the fighter would fall.

The two arms were a little sore, but Qin Feng still used all his strength to hold the operating lever into his arms.

The altitude continued to decrease, the speed increased, and finally, by the time the altimeter continued to shake at a position of two hundred meters, the plane had leveled out.

Qin Feng wanted to speak, wanted to call, but he couldn't say anything now, as if even his throat was subjected to a strong centrifugal force.

Qin Feng could only continue to pull up.

Finally, as soon as his body was loosened, Qin Feng lay down on the seat softly, this time, he really didn't have half the strength, he called weakly: "006 call the base, it has flown to supersonic speed, ask to return." ”

"006, return immediately." On the other side of the radio, there was a lot of excitement.

Qin Feng pulled up the fighter plane and returned to the field at an altitude of eight thousand meters, and when the plane came to a standstill, Qin Feng leaned on the seat and couldn't get up anymore, his body was extremely tired.

His eyes slowly closed, and he rested for more than ten minutes, only then did he have enough strength, and when he opened his eyes, Qin Feng was immediately taken aback.

In the test flight yard, all kinds of high-risk test flights are carried out every day, so everyone is used to it, but today, next to his plane, there is actually a sea of people.

These people must have arrived a long time ago, but because they were resting on their seats, no one came to disturb them, so they let themselves stay in their seats until now.

Qin Feng stood up and saw the dean, Mr. Gu and the others, all at the front.

"Qin Feng, you did it!" Mr. Gu watched Qin Feng come down and said excitedly: "You successfully completed the low-altitude high-speed test flight of our J-8 fighter, and you flew our aircraft to supersonic speed at low altitude!" ”

This is a remarkable achievement, more reliable than a static test on the ground, and what does it mean to fly at this speed in a dense atmosphere?

The surface of the fighter, the pressure on each square meter, is more than 8,000 kilograms!

If you are specific, every square meter is equivalent to ten small QQ cars pressed on it! (There is no small QQ in this era, so let's have eight 212s.) ）

This pressure is the most terrifying, if the fighter continues to shake, under this pressure, the entire aircraft will disintegrate in an instant.

Needless to say, the aircraft disintegrated, just the cockpit windshield in front of Qin Feng, once it was crushed, then Qin Feng's body would be pressed with eight tons of things in an instant, what was the result?

Qin Feng took a huge risk this time, but now, Qin Feng has succeeded!

"Dean, Mr. Gu, I did it." Qin Feng said.

The people in front of him, all of them had red circles under their eyes, and at this moment, a person suddenly came out next to him, opened his arms, and hugged Qin Feng tightly.

These arms are so powerful, for a moment, Qin Feng has a delusion, is this going to pick himself up and take him away? It's the same as robbing a daughter-in-law in ancient times, he is a man, alas, it's not good for a man to hug a man like this.

Qin Feng was helpless in his heart, but he couldn't say it, because he knew that it was because the person in front of him had a deep affection for his revolutionary comrades.

It's Lao Wang.

Although before the test flight, Lao Wang obstructed in every way and was unwilling to carry out these high-risk subjects, but Lao Wang had no selfish intentions, and it was also for the sake of safety.

Now, when Qin Feng started the test flight, Lao Wang had been waiting for news in the flight control room, and he found that his heart had already flown to the fighter, right next to Qin Feng.

Now, Qin Feng finally came back safely, Lao Wang didn't know what was going on, he couldn't suppress his excitement, and tightly hugged Qin Feng as a revolutionary comrade, and tears were already flowing down involuntarily in front of Lao Wang's eyes.

"Qin Feng, you are a good comrade."

Lao Wang sincerely admired Qin Feng.

Fortunately, at most, it is just the embrace of the revolutionary comrades, looking at the north, the leader of the woolly bear, that is the most favorite to meet and kiss, think about two old men, hugging each other and nibbling, that scene, how funny and funny it is.

Moreover, they are not ashamed of this, and they are very proud of it, believing that it is a way to increase mutual affection, and even use large posters on the streets of many cities to make propaganda.

It is said that when the female head of state of a certain country went to the Soviet Union, she was also asked by Lao Bo to come to this set, but people flashed and avoided it.

"When you got on the plane, I wanted to see you off, but after thinking about it, I didn't dare to go because I was afraid that you wouldn't be able to come back." Lao Wang said.

When he said this, everyone was emotional, in fact, everyone had the same idea in their hearts.

"What are you afraid of, I believe in our plane, isn't it a good way to come back?" Qin Feng said: "Now, our test flight can finally come to a successful end, by the way, when I was on a test flight, I saw that the watch speed was just 1,002, how could it be supersound?" ”

Qin Feng still had a doubt in his heart.
