The sound is a bit weird.

The volume is small, sometimes strong and sometimes weak, and is not stable.

What's going on?

Zhou Hai, who was walking towards two aviation doctors, was about to undergo routine medical examinations, frowned slightly, turned around immediately, looked up at the sky, looking for the source of the roaring sound of the ws-10 "Taihang" turbofan engine.

With his extremely keen hearing, rich fighting aircraft logistics and maintenance technology and familiarity with the "Taihang" turbofan engine, Zhou Hai was able to judge whether there was any problem from the change in the engine roar.

The roar is strong and weak, which is absolutely abnormal.

With his eyes on the sky northwest of the base, he spanned five or six kilometers away, and then a small and extremely familiar figure came into his eyes.

That's, a real metal monster.

The sharp airspeed tube, a slender and round black head like a sword, a light gray style painted with bright red HNA August 1 logo, a water drop-shaped glass cockpit that refracts the bright morning light, and a red number No. 578 containing oriental colors.

In addition, there are unique close-range canards, heavy and stable fuselage, double vertical tails as sharp as blades, thick and simple tail hooks, two WS-10a "Taihang" large thrust turbofan engines, and the iconic aerodynamic layout that shocks and looks up to world aviation history - the central lift body.

All these elements blend together to form the world's unique active high-level war killing weapon - the J-15 "Flying Shark" heavy carrier-based aircraft.

J-15!

The noble and proud Eastern members of the Su-27 family originated from the Su-33 "Sea Flanker" heavy carrier-based aircraft. The J-15c "Tiger Shark" serious grandfather was the third-ranked terrifying existence in the world before his grandson was born.

However, now, this J-15 "Flying Shark" with the number No. 578 belongs to the Qingcheng Base combat sequence, does not have the elegant attitude it should have. It is not only embarrassed, but even a little critical.

"What happened!"

Looking at the J-15 "Flying Shark" in extremely poor flight conditions, Zhou Hai was stunned for a moment after careful observation. His black pupils shrank, his face suddenly changed, and he suddenly became serious.

Something happened!

Yes, something happened indeed.

In the blue sky, the entire J-15 "Flying Shark" was slow, and its flight posture was unbalanced, shifting and tilting to the left, losing its normal horizontal posture, no longer as calm and elegant as before. There were streams of thick white smoke rising from the tail end of the light gray machine abdomen like a tide, which quickly drifted backwards. The tail nozzle of the engine position on the left sprayed dazzling orange-red high-temperature flames.

The young carrier-based pilot stayed in the water-drop-shaped glass cockpit was a little panicked, his forehead was covered with pearl-sized crystal sweat beads, and a hint of nervousness appeared in his handsome face.

Through excellent vision that is extraordinary as unhuman, Zhou Hai saw the reactions of the entire J-15 "Flying Shark" and the pilot clearly, his heart sank, and his face was serious:

"The left fires, is this a bird hit?"

White smoke, left fire, fire broke out, and the body was unbalanced. These key words indicate a situation - the No. 578 J-15 encountered the highest level of first-level air special situation.

Level 1 air special situation, this is the highest level among the air special situation levels, and it is also the easiest level to reach among all types of flight accidents. It is extremely dangerous and is only half a step away from the destruction of the plane. If you are not careful, you can only have a small fighter model in the urn.

Every time you take off and land, death is accompanied by - this sentence is by no means false.

"boom!"

The roar of the turbofan engine exclusively belongs to WS-10a's "Taihang" resounds across the world, from weak to stronger, spanning more than 7,000 meters, covering the entire Qingcheng base.

The silver-gray war eagle, which maintained an altitude of about 800 meters, headed straight to the base at a speed of more than 300 kilometers per hour along the route. The young ship with a high concentration in the cockpit flew. While stabilizing his mind, he used his superb flight skills. With the long-range control and assistance of the tower personnel, he worked hard to control the war eagle in critical condition and flew to the base's emergency landing area.

"Buzz!"

Just as the J-15 "Flying Shark" with the engine caught fire and emitted thick smoke approached the base, in a moment, the most sharp and anxious air defense alarm sounded in the terminal of the broadcast sound system of the Qingcheng Base.

The highest frequency of air defense alarm sound, such a combination, means the activation of the highest level of emergency plan!

"All units at the base should pay attention to it, and immediately implement the first-level emergency plan. This is not an exercise, repetition, this is not an exercise!"

The next second, the extremely serious voice of the middle-aged controller at the Qingcheng Base Tower spread throughout every corner of the base through the sound element system terminal.

"Level 1 emergency plan?!What's going on..."

Dai Minmeng, who stood at the edge of the swimming pool, heard the familiar and dangerous sirens and notification content, and his eyebrows were tightened. This sudden level-one emergency plan caught him off guard.

Looking up, his keen eyes searched according to the gradually loud sound of the turbofan engine. Soon, a small and vague figure was found in the sky in the northwest. It could be seen that it was a fighter jet, but it was impossible to distinguish the specific model.

By listening to the sound and identifying objects, the experienced Dai Minmeng can judge that this is the roar of the Taihang turbofan engine, but it is impossible to determine the specific model.

"All of them terminated their training and went ashore immediately. Lifeguards were in the water. Everyone assisted the pilots to evacuate!" After looking at Dai Minmeng, who knew the seriousness of the matter, did not continue to delay, had a calm mind and clear mind, and immediately issued an order to make relevant arrangements in accordance with the requirements of the first-level emergency plan.

The voice was loud and powerful, without any panic. As the former captain of the carrier-based aviation force, the special air situation he had contacted and experienced was comparable to a regiment of the second-line air force.

In a blink of an eye, the command spread throughout the swimming pool like water waves and entered everyone's ears.

Terminate training!

Initiating and implementing a first-level emergency plan means that everyone must immediately put down what they are doing, take their place, and make corresponding preparations accordingly according to the content of the emergency plan.

As the highest commander of the J-15c modification training and the Dai Min League, with extremely high military quality, now only one core preparation work needs to be done - immediately organize the evacuation of the team to ensure the safety of each participating member's life.

The twelve pilots trained in this modification are not only precious treasures of the Air Force and HNA, but also new seedlings of carrier-based pilots this year. If there is a mistake, even if one is lost, you will know what it means with your toes.

Of course, the action to terminate the training and evacuation of pilots is just a matter of precaution. Unless the fighter jet in the sky, which is currently unknown to the specific aircraft, suddenly lost control when it arrived at the base and fell directly into the swimming pool, it would not be possible to cause any losses to the pilots in the training.
