"Okay, lower it to a height of 500 meters." Lin Jian carefully observed the special training aircraft group more than 100 meters away, and issued another order to increase the flight difficulty.

The 500-meter flight altitude seems nothing, but for the Warhawk with a speed of 700 kilometers per hour, it only takes 2.5 seconds to hit the ground and cause a flight accident.

After more than ten seconds, the special training aircraft group gradually decreased to a flight altitude of 500 meters. The endless hilly landforms in the southeast quickly disappeared, and low-altitude cumulus clouds emerged one after another.

At this height, the complex landform of the southeast hills has suddenly doubled the difficulty of flight.

Two J-10a canard fighters were accompanied by them, flying at a low altitude of 500 meters, one on the left and one on the right, and accompanied by the special training aircraft group.

"All members of the special training crew, are there any problems?" Lin Jian's face was serious.

“No. 8 has reached its limit.”

As the sweaty HNA student Wu Qiang made a somewhat uncomfortable sound, the voices of several students suddenly sounded in the encrypted communication channel.

Three people in the Shiyuan,

Three people in the sea courtyard.

The difficulty of a 500-meter formation to penetrate at a low altitude is far beyond that of 800 meters.

"Practitioners who have reached the limit should maintain altitude, course and speed, persist to the predetermined airspace, and those who have not reached the limit should be reduced to an altitude of 400 meters." Lin Jian heard the answers of many flight students and made corresponding arrangements, stared at the entire fleet and issued new orders.

reduce!

Continue to lower!

Six falcons that have reached their limits maintain their original flight altitude, heading and speed. The remaining seven new falcons and one l-15a falcon face downwards, lowering the altitude, forming a 400-meter-relative height with the ground.

In a blink of an eye, a HNA student Luo Zhenghan heard a voice: "Report, No. 7 has reached its limit." He focused his attention, his eyes were watching the rapidly changing hilly terrain ahead through the glass cockpit, and his forehead was covered with sweat.

Low-altitude penetration, the lower the height, the higher the operation difficulty, and almost showed a geometric increase.

With Luo Zhenghan reporting his own situation, Tong Yuan and Yi Xuewu also reported the situation, staring at the changing terrain, breathing rapidly, and enduring the high overload caused by low-altitude high-speed flights.

Now, Zhou Hai is the only one left in the entire special training group. Bai Tangfei, who is breathing heavily, Yang Min and Wang Zhuyu, who are on the verge of limits.

"No. 2, No. 3, No. 4, how are you doing?" Zhou Hai controlled as he wanted. The altitude of 400 meters was like a piaolao for him. He didn't care about the high overload of flying low altitudes. He looked at the three falcons on both sides and cared about.

No. 2 is Wang Zhuyu, No. 3 is Yang Min, and No. 4 is Bai Tangfei. The number ranking is determined according to the comprehensive score.

Wang Zhuyu's face was red, her breathing was heavy, her eyes were like sharp sharp knives, staring straight at the screen of the onboard avionics system, and operating according to the changes in the terrain: "No. 1, I'm fine."

"It's okay." Yang Min tried hard to control the fighter plane and signaled that he was fine.

Bai Tangfei's voice was solemn, gritting his teeth tightly, and beads of sweat as big as mung beans slashed across his cheeks, his breathing became heavier, and the rapidly changing complex terrain and high overload made his brain unable to keep up: "I'm almost at my limit."

"Persistence to the limit, efforts not to the limit, continue to fall, 300 meters." Commander Lin Jian's voice was calm and calm, and he issued a new order.

Zhou Hai's face was calm, his eyes looked forward, and his right hand gently pressed the rod, his movements were gentle and gentle, controlling the sensitive and lightest falcon under him, lowering his height.

Three hundred and fifty meters!

With his strong physical fitness, Zhou Hai easily withstands the high overload caused by a speed of 700 kilometers per hour.

"Report, No. 4 has reached its limit!" Bai Tangfei shouted with a rapid breathing sounded. The long-term low-altitude penetration that was completely close to actual combat made him unable to hold on and had to maintain altitude and speed, and did not choose to force the rod.

Two seconds later,

The remaining three l-15c falcons were lowered to a height of 300 meters.

Lin Jian, wearing a new anti-lood suit, easily resisted high overloads through technological power, held the metal joystick steadily, with a serious face, looking at the three Falcons from high to low: "No. 1, No. 2, and No. 3, each reported the situation."

“No. 1 is normal.”

Zhou Hai's voice is as old as before.

"Can you still stick to the No. 2." Wang Zhuyu's pores were seeping sweat from her body, and she held the joystick tightly with her right hand.

Yang Min gritted his teeth and felt that his body was pressed on the seat by a high overload. He used all his strength to control the war eagle under him, and constantly adjusted his flight posture based on the information obtained: "No. 3 has reached its limit."

"Can the height of No. 3 maintain, No. 1 and No. 2 continue to decline?"

Looking at the white numbers smeared with 109 and the 107 Falcon No. 1-15c, Lin Jian, who had already read the information of Zhou Hai, did not respond in his heart. Instead, he was very satisfied with Wang Zhuyu's performance and asked.

Hearing the rapid breathing sound from Wang Zhuyu in his ears, Zhou Hai frowned slightly and responded: "No. 1 is fine, No. 2, don't force support."

"No. 2 can lower the height by another 50 meters." Wang Zhuyu didn't care about Zhou Hai's advice. She knew that she was on the verge of limit, but she refused to give up. She gritted her teeth and replied to Lin Jian.

As Wang Zhuyu, who has gone through a lot of hardships to become a female flying girl, has her own will and ideas.

The limit is used to break it!

Target, 250 meters flight altitude!

Lin Jian stared at the two falcons with his eyes and issued a new order: "No. 1, 200 meters altitude preparation, No. 2, 250 meters altitude preparation, start."

After receiving the order, Zhou Hai, who was breathing smoothly, continued to press the rod downward and steadily lowered the flight altitude. Wang Zhuyu on his right hand drove the No. 107 L-15c Falcon and followed closely. Every ten meters of decline, the operation difficulty will be increased a little.

"I'm reaching my limit."

A few seconds later, Wang Zhuyu looked at the left screen to give flight parameters. The tight string inside was relaxed, a smile appeared on her face, and she was breathing in high concentrations of oxygen.

"No. 1 reaches the target height, report to the command plane, please instruct." Seeing that Wang Zhuyu was not holding on, Zhou Hai breathed a sigh of relief and looked at the ground scenery that was almost within reach. After it was lowered to a height of 200 meters, he called Lin Jian through the encrypted communicator.

There was a little eager to try in my words, but there was no physiological reaction to flying low altitudes for a long time.

Compared with low-altitude penetration, Zhou Hai prefers thrilling ultra-low-altitude penetration, and it is fine to break through a thousand kilometers.

"I can't compare to you." Feeling Zhou Hai's relaxed and normality, Wang Zhuyu sighed while adjusting his flying posture.

Monster! Yang Min, who maintained a height of 300 meters, couldn't help but twitch the corners of his mouth.

“…”

In the encrypted radio communication channel, the other students were silent. After the test of low-altitude penetration, everyone deeply felt the gap with Zhou Hai.
Chapter completed!
