Not to mention, when Yang Jing sat in the back seat of the cabin, his heart beat wildly for no reason. He was excited and nervous, which was necessary.

"Boss, don't worry, I'll take you to heaven quickly and then bring you back safely." George, who was sitting in the front seat, turned his head and said to Yang Jing with a smile, "Don't do anything else. Just do the few points I just told you, and I will guarantee you are fine. Remember, seat belts and oxygen masks, as long as these two are fine, you will definitely have no problem in heaven."

Yang Jing squeezed out a smile and gave George a thumbs up.

When things came to an end, Yang Jing realized that he was not as calm as he thought. It seemed that the training in character was not enough.

Everyone in the hangar left the hangar, George started the engine, and then the plane slowly drove out of the hangar.

"Radio test, Nest No. 3, Nest No. 3, here is Flying Fox No. 1, here is Flying Fox No. 1, please calibrate the radio."

Yang Jing didn't squeak, but after a burst of current interference in the built-in radio headset in the helmet, another clear sound rang out, "This is Nest No. 3, I received a radio calibration request, Fei Fox No. 1, your signal is very normal and clear."

"Thank you. Flying Fox No. 1 has slipped out. Please give instructions from the nest No. 3."

"Flying Fox One, please skate to 24l and wait for the takeoff order."

As soon as the tower was issued, Yang Jing felt the fuselage shock, and the plane began to slowly accelerate on the taxi track, and then taxied towards the takeoff track.

A few minutes later, the plane stopped steadily at the end of the takeoff runway, and George's voice sounded again: "Nest 3, Flying Fox One is ready, requesting takeoff."

"I received it. Flying Fox One can take off in forty seconds. In addition, the visibility today is very good. There is probably eight crosswinds during takeoff. Please pay attention to the crosswind. Flying Fox One, Nest No. 3, wish you a successful flight today."

"Thanks."

After the call was over, Yang Jing felt that the engine behind him made a stronger and stronger sound. It was obvious that the aircraft engine was increasing the output power.

When the time came, Yang Jing felt a violent feeling of pushing his back suddenly, as if his body was pressed down hard by an invisible hand. Only at this time could Yang Jing clearly distinguish the gap between the fighter and the civil aviation passenger plane.

Although ordinary civil aviation passenger planes also have a clear sense of pushback when taking off, they are far from comparing with the feeling of pushback when taking off. The two are not on the same level at all.

In the normal oil-carrying mode, f15 can take off in just 500 meters, and if it is in the intercept mode, that is, with a small amount of oil, it can even take off in only 300 meters.

Therefore, when the f15 takes off, the pilot is under a large acceleration overload, which is why there is such a strong sense of pushing back.

Almost in less than ten seconds, Yang Jing felt his body sink suddenly. The next moment, everything on the ground began to quickly leave him, and he began to rise quickly as if he was riding on a roller coaster.

The climbing speed of the fighter is incomparable to that of civil aviation passenger planes. The extreme climbing speed of this thing is as high as 254 meters per second. In other words, under the extreme case, the F15 can quickly rise from the ground to a height above Mount Everest in just over 34 seconds!

Of course, George would not use such an extreme climbing speed when Yang Jing first rode a fighter. After all, Yang Jin needed a process of adaptation. But even so, the climbing speed of f15d jumped Yang Jing. Before Yang Jing even recovered from the sudden feeling of overweight, he found that the plane had steadily flew to an altitude of more than 2,000 meters.

Don't ask Yang Jing how he knows the current altitude of the plane. It's very simple. The back seat he is riding in has an altimeter display...

The plane quickly entered a stable flight state. At this time, from a height of two thousand meters down and around, it was full of blue sea water. Guam, which originally felt very wide, was completely surrendered to himself.

Looking at this height, Yang Jing immediately remembered a classic Internet term - Ah, the sea, all of you and his sister are water!

To be honest, I couldn't feel the true artistic conception of this sentence before, but today I was flying above the sea in f15d, and the most realistic artistic conception of this sentence can be most thoroughly reflected.

As F15d continues to accelerate to the east, Guam gradually disappears, and the water and sky are really the same color around it! The sky is blue, and the Pacific Ocean is blue under you. You can see it at a glance. Except for this clear and intoxicating blue, you can no longer see any other colors.

In fact, this is an ultimate purity! In this pure blue color, Yang Jing could not even feel that he was riding in a fighter plane and was flying at a speed close to the speed of sound. He only felt that he was floating in mid-air. That feeling was wonderful.

But George's voice broke the feeling, "Boss, do you think your body is fine? I mean, at this speed, you don't feel any discomfort?"

Yang Jing subconsciously shook his head, and then realized that George, who was sitting in the front seat, could not see him at all. Then he said, "No problem, I don't feel any discomfort at this speed."

George smiled and gestured a big thumb from the top of his head, "Boss, I am really surprised by your physical fitness. Now our speed is Mach 0.9, which is 1080 km/h. Now your movement speed in the air relative to the earth has exceeded 300 meters/sec."

"Wow, so fast? But I can't feel it." Yang Jing said the truth. In this environment, there is no reference material around, and even if it is flying Mach 10 now, I can't feel it.

However, Yang Jing could still see that some parts of the wings would occasionally produce some obvious local shock waves of airflow. Yang Jing knew this phenomenon, because although the overall speed of the aircraft has not reached the speed of sound, the speed of the aircraft has reached Mach 0.9, so the airflow in some parts of the aircraft has actually reached the speed of sound, which is why this local shock wave phenomenon is generated.

This is still the current situation where the aircraft's flight altitude is only 2,000 meters. If the aircraft is at an altitude of 11,000 meters, the speed of 1,080 kilometers per hour has actually exceeded the speed of sound. Because at an altitude of 11,000 meters, the speed of sound is only 1,066 kilometers per hour, which is far lower than the speed of 1,224 kilometers per hour on sea level.

The higher you go, the easier it is to break through the sound barrier.

"Haha, do you want to speed up? The maximum speed of this aircraft can reach Mach 2.5, but I have never flew so fast, but I used to fly two Mach 2."

"Okay, you can speed up and let me feel the pleasure of supersonic speed!"

"Ok!" After George finished speaking, he began to push the power putter. Yang Jing felt a larger feeling of pushing back came in an instant.

Even without reference objects, Yang Jing could feel that the plane was accelerating, especially the roar of the engine behind him was getting louder and louder, and the originally transparent air behind the wings could clearly see the flow of the airflow.

Even though Yang Jing was sitting in the sealed cabin at this time, he seemed to be able to feel that the fuselage was under great pressure at this time.

In fact, breaking through the sound barrier is not a good thing. When the plane approaches the speed of sound, in the front of the high-speed plane, due to the generation of local shock waves, the air is compressed and the resistance increases sharply. At this time, all parts of the plane even in operation have strange reactions. If a slight mishandling is done, the plane will be destroyed and killed.

Therefore, supersonic flight is certainly a stimulus that makes the pilot's adrenaline rush, but the danger is quite high. It's okay to control it. If the aircraft's structure or fuselage is a little malfunctioning, then the aircraft that is fine at ordinary speed may disintegrate at the moment of breaking through the sound barrier.

Yang Jing once watched a video of a US F18 Bumblebee taking off from an aircraft carrier for training missions. As a result, it was a supersonic flight at a low altitude. When a "sonic blast" was formed behind the wings, the "bumblebee" suddenly disintegrated in the air. The scene was extremely tragic, and the pilot didn't even have time to parachute, so he went to God for tea with his love aircraft.

Now, Yang Jing could clearly see that as the airflow ejected from the engine became louder and louder, a white "sound cone" had appeared in front of the head of the aircraft. The sound cone quickly extended to the rear, and finally a white "sonic bomb cloud" with a shape similar to that of the large horn was formed behind the wings.

This kind of sonic boom cloud is because the airplane compresses the surrounding air because it is too fast at the moment when it crosses the speed of sound, thus causing the water vapor in the air to condense into a cloud. Finally, a conical sonic boom cloud will be formed behind the wings with the fuselage as the axis.

However, this kind of sonic boom cloud is not often seen. Only when flying on the sea or when the air humidity is high can this extremely beautiful sonic boom cloud be produced.

Today, Yang Jing was very lucky. He saw this extremely rare sonic bomb cloud when he first performed a transonic flight.

With the emergence of the sonic boom cloud, Yang Jing heard a very explosive "bang" sound, as if a big bang was detonated in his ear. Then, everything returned to silence. The sonic boom cloud outside disappeared. The sound of the engine jetting airflow that was a little harsh just now was gone at this time. The only sound that could be heard in the entire cabin was the sound of the engine moving.
