After the busy work, the letter could not be sent out for the time being, and Yang Xiaolong, as a flight instructor, was performing the intensive adaptive training task of ordinary Class A and B students.

Zhou Hai, who was the leader of the First Squadron of the Red Army, received an order from Deputy Captain Lei to go to the academy airport to start the daily training of the First Squadron of the Red Army after resting for more than ten minutes.

……

Time flies and passes gradually.

Shicheng Flying Academy and HNA Flying Academy both fell into a busy and intense state of high-intensity training.

The adaptive training is composed of basic tactical maneuvering, over-the-horizon air combat characteristics, close-range combat, emergency take-off, combat readiness highway take-off and landing, and so on.

These training contents have never been touched before.

It's just that the subjects of adaptive training about air combat are still too difficult for ordinary students.

Even if the precious knowledge and skills are in front of you, limited by talent and wisdom, you can only learn a rough idea and have the most basic combat requirements.

As for those who want to comprehend the essence of air combat, they need continuous air combat training on a year-by-year basis before ordinary cadets can be transformed into qualified combatants - rookie pilots in the popular sense.

The days passed day by day, and in the blink of an eye, it was the end of summer.

Northwest of Shicheng Flying Courtyard, the steep and majestic Taihang Mountains.

In the distance, the sun is setting, and the sky is full of red glow.

"Buzz!"

The roar of the S-17 turbofan engine resounded over the northern part of the mountainous area, spreading all around, and the silver-gray No. 109 L-15C Falcon with a science fiction atmosphere, bathed in the glow, like a sword in the sky, swept over a towering dangerous peak at a high speed of 700 kilometers per hour, and steadily maintained a relative height of 200 meters from the ground.

"Boom!"

Behind them, seven Falcon planes maintained a tight formation in a straight line, following the No. 109 L-15C Falcon, like sharp and sharp arrows, successively skimming this towering and dangerous peak in the northern mountains, maintaining an altitude of 200 meters.

Here, it was once a battlefield, the eastern edge of the second echelon of the motherland's topography, and the eastern boundary of the Loess Plateau - Taihang Mountain.

"Each machine reports the situation."

As the supreme commander, Zhou Hai, with a calm face and eyes looking straight ahead, flew at the forefront of the group, assumed the leading role, held the joystick tightly in his right hand, and controlled the low-flying L-15C Falcon to fly along the predetermined route, implement the standard plan, turn on the radio equipment, and give instructions to the planes of the First Squadron of the Red Army.

"Number two is normal."

Wang Zhuyu, who was suffering from a high overload, was highly concentrated, did not dare to be distracted, held the joystick with both hands, and with bright eyes, he firmly stared at the No. 109 L-15C Falcon more than 100 meters ahead.

After a three-month special training in air combat, Wang Zhuyu has already broken his limits and is able to fly at an altitude of 150 meters at a minimum of 150 meters.

"Number Three is normal."

"Number Four is normal."

Bai Tangfei and Yi Xuewu, who were at the same level, both replied, breathing a little rapid and a little strained, but they were fine, and they were in a normal physiological reaction.

"Number Five is normal."

"Number Six is normal."

"Seven is normal."

"Number Eight is normal."

In the encrypted radio communication channel, the other four crash course students belonging to the 1st Squadron responded immediately, breathing quickly and heavily.

Speed 700, height 200.

The low-altitude, high-speed, and complex mountainous terrain to penetrate the defense, which is extremely dangerous, makes the ordinary flight students of the Stone Academy talk about the color change, and it is the daily training of the first squadron after the special training of air combat.

In such a flight state, if you make a mistake or encounter an accident, you will encounter a first-class flight accident that destroys the plane and kills people.

"All planes maintain a high degree of vigilance, cheer up, and strictly prohibit distraction, and are about to enter the complex terrain in the middle of the Taihang Mountains."

Zhou Hai heard everyone's answers, watched the satellite detection and terrain data given by the multi-function display screen with both eyes, stared at the steep mountainous terrain in front of him, and gave a reminder.

As an important geographical demarcation line, the terrain of Taihang Mountain is high in the north and low in the south, steep in the east and gentle in the west, mostly fault structure, the terrain is complex and steep, the relative height difference is large, and there are countless peaks of various sizes.

As the supreme commander of the 1st Squadron, Zhou Hai needs to inquire about the flight situation of each aircraft every 15 minutes, check whether there is any situation, and be responsible for training the safety of each aircraft and flight students.

This is a tedious job, and it is also the reason why Zhou Hai is reluctant to be promoted.

He's a pilot who likes to go it alone, well, in a colloquial sense, it's troublesome.

"First Squadron, please report on the flight." In the encrypted communication channel, the crisp and ethereal voice of Lin Ying, the controller of the tower of the Shicheng Flying Courtyard, came out, and asked Zhou Hai.

Zhou Hai changed his flight attitude according to the topographic data of the airborne exploration, swept over the craggy peaks on the right hand side at high speed, and immediately reported the situation to the academy airport: "Report to the tower, the first squadron is flying normally, and is carrying out flight training, and the process is more than halfway through, and it is about to cross the middle section of the Taihang Mountains." ”

"The terrain in the middle section of Taihang is complex, pay attention to safety, the first squadron." Lin Ying, the controller of the tower, recorded the flight report data and reminded Zhou Hai of the information.

"The 1st Squadron received."

Holding the throttle valve firmly with his left hand and holding the lever with his right hand, Zhou Hai responded after hearing the controller's reminder.

The roar of the turbofan engine resounded all around, and the eight falcons of the 1st Squadron, bathed in the glow, faced the sunset that was gradually falling in the distance, shuttled through the complex and dangerous middle section of the Taihang Mountains, and trained the ability to penetrate the defense at low altitude in complex terrain.

The same students of the Shicheng Flying Academy, the first squadron composed of all members of the crash course, and the ordinary flight students of class A and B, there is already a gap like a moat.

While ordinary cadets are still having a headache for combat-ready highway take-off and landing and regular tactical subjects, the elite cadets of the crash course have already reached the qualified level of combatants and have mastered high-difficulty flight techniques such as low-altitude and complex terrain penetration and rich experience in live-ammunition shooting.

This is the gap!

The gap between the ordinary and the elite!

"Boom!"

Thirty minutes later, the red glow of the sunset was gradually swallowed up by the horizon, and as it passed through the precipitous Taihang Mountains, the 109th L-15C Falcon at the forefront of the team took the lead in raising its head and climbing, piercing into the sky like a sharp sword, breaking away from the flat and vast plain terrain.

The remaining seven silver-gray Falcon planes followed closely, forming a straight lineup, with a pointed orange-red tail flame dazzling, and the eight Falcon planes that had completed the training mission of low-altitude penetration of the Taihang Mountains swept towards the sky composed of red glow and blue background overhead.

It's dark, slightly dark.

Night is coming.
