Kang Xiaoshuai piloted the F15C fighter numbered "LN334" to climb away from the British's aircraft formation, ready to make the next attack on the remaining aircraft. Major Staffe and his men saw the opportunity to lower the flight altitude to about 50 meters above the surface.

"I'm rubbing, this Nima is the master who can play, this is the rhythm of forcing your brother to play low-altitude play!" When Kang Xiaoshuai turned around, he found that the British had lowered the flight altitude to the point where it hurt him.

The so-called low-altitude passage refers to the flight of the aircraft from the airport runway or from the front of the viewing platform during the flight, which is a way for the aircraft to express respect and a kind of etiquette. Basically, the flight altitude of the aircraft in the range of 100m-20m can be regarded as low-altitude flight. Well, the perverts of those aerobatics are able to reduce this height to a distance of about a meter from the ground, which is not in our discussion.

There are certain technical requirements for pilots to fly the aircraft for low-altitude clearance, because when conducting low-altitude clearance, it is mainly up to the pilot himself to visually measure the altitude, and the pilot's line of sight is always outside the cockpit, which requires the pilot to have accurate judgment and accurate flight technology.

Obviously, our Kang Xiaoshuai is not the kind of pilot with the ability to pass through the field at low altitude, and this is the first time that Ya has flown an F15 fighter without the assistance of a clone instructor. What the hell is the ultra-low-altitude passage, it is obviously beyond the curriculum for a flying schoolboy like him.

As for controlling the F15C's 20mm "Vulcan" cannon to attack the British's aircraft while diving, it is also a technique that Kang Xiaoshuai is not very good at. When a pilot with a psychological quality like him is doing a high-speed dive, it is estimated that 99 percent of his attention is focused on how to pull the plane up.

Flying close to the sea will encounter complex situations such as wind shear and downdrafts, and may even hit seabirds, these situations are not our primary school pilot Kang Xiaoshuai can properly handle, if he wants to repeat the old tricks to rely on the wake brought up by F15C to kill the British, it is really dangerous, for a while Kang Xiaoshuai himself can't make up his mind what to do.

"Oh, your sister, I really think that your uncle can't do anything about you, I'll reward you with a large stun bomb later, I have to let you know that your uncle is always your uncle!" Seeing that the British planes flying close to the sea began to flee separately, Kang Xiaoshuai decided to use the method mentioned by the E4 ship's air control rough embryo to break the sound barrier and cause a sonic boom to deal with the British.

Although he has not personally piloted a plane to break through the sound barrier, Kang Xiaoshuai has indeed experienced the feeling of breaking through the sound barrier when the clone instructor takes over the F15D training aircraft. Well, at least he didn't faint while he was wearing an anti-load suit at the time.

"Major, the devil's plane of the Great Song people has gone away, and your plan has succeeded." The navigator behind Major Stav shouted loudly when he saw the F15C flying away.

The British vision is beautiful, but the reality is cruel. Kang Xiaoshuai drove the F15C to a higher place not to let them go, the F15C needs a little distance to fly at supersonic speed.

Soon, the plane with its ass in flames turned back again. This time it made a much louder noise than the last time, could it be that the Great Song pilot really dared to fly the plane at a distance as close as the sea? You must know that the distance of tens of meters is for an aircraft with such a high speed, and any small mistake can cause an irreparable mistake, and before you have time to react to correct the mistake, the plane will already crash into the sea. This Da Song pilot is really a master of art and bold! Major Stav thought to himself.

Boldness of execution stems from superb skill!? It didn't exist, and at this time, Kang Xiaoshuai's palm holding the joystick was already full of sweat. The last time he experienced a flight that broke through the sound barrier, Kang Xiaoshuai was still in the dome light curtain, well, to be exact, due to a series of problems that Kang Xiaoshuai could not deal with at that time, the flight that broke through the sound barrier was completed by a clone instructor sitting in the back seat of the F15D.

"You can, Kang Xiaoshuai! In just a few seconds, the shock wave from the F15C's breach of the sound barrier is enough to shred these British planes. By the way, if something happens, this ejection seat can save my life, right? Kang Xiaoshuai was muttering to himself cheering himself up.

How lacking is this to expect to have extravagant hopes for that ejection seat when doing supersonic flight, and when doing supersonic flight at such a close distance on the surface of the Caspian Sea!?

Kang Xiaoshuai chose to fly at supersonic speeds at a distance of about fifty or sixty meters above the British aircraft formation, well, on paper, this is no longer a low-altitude field in the strict sense.

In fact, flying at an altitude of about 100 meters above the sea surface, Kang Xiaoshuai is still likely to encounter complex and changeable wind shear and downdrafts. As for seabirds, they are animals, and they don't have an altimeter when they fly, so what's impossible to fly to a hundred meters in the air?

At such an altitude to break through the sound barrier, Kang Xiaoshuai will also encounter shock waves that cause the airflow through the wings and fuselage surfaces to be disturbed, which will make the aircraft shake violently and bring difficult maneuvering.

To put it simply, the rookie pilot is likely to face the windshear and downdrafts and seabird problems that he has been afraid of, as well as the operational problems of the aircraft when breaking the sound barrier that he thinks he can better control. Kang Xiaoshuai inked for a long time and the risk of implementing the action plan formulated was even higher than directly doing a subsonic low-altitude pass at the head of the British aircraft formation!

Uproar——! Rumble! It was too late, and before Major Stave and his men could come to their senses, the Great Song Spitfire roared over their heads with a strange roar. As the Spitfire was closest to the formation, there was an explosion in the sky that hurt the eardrums of the British pilots and navigators.

"What's that white cone-shaped fog cover? Are the Great Song people going to poison us? That was the last question on Major Staff's mind before he crashed out of the shattered plane into the sea.

The loud sound from the sky is undoubtedly the legendary sonic boom, and the white mushroom-shaped thing is called the tone cone, it is due to the previous accumulation of shock waves caused by the excessive pressure at the front end of the object, and after the object breaks through the sound barrier, the huge pressure accumulated in front of the fuselage suddenly disappears, and the pressure caused by the instant decreases, resulting in an instantaneous decrease in the condensation temperature of water vapor in the air, so the water vapor condenses into small water droplets, and becomes a state like a cloud to the naked eye. A cone-shaped cloud that spreads evenly from the front of the wing to the rear of the air.

Of course, not every time the plane breaches the sound barrier, the sound cone can only be observed when the sound barrier is breached, and there is enough water vapor in the air around the plane to appear this sound cone landscape. Kang Xiaoshuai flew the F15C fighter jet at the speed of sound at a distance of more than 100 meters above sea level, apparently able to collect the water vapor that formed the sound cone.
