I have no regrets, do you have anything else to say? The sudden emergency during the test flight mission brought the pilot's conversation in the cockpit, which moved people to tears in an instant.

"I can't imagine what they were thinking, I only know that they saved the plane." The test pilot is the closest to danger.

They clear the path for the generation of combat effectiveness in the military. A reporter from the main broadcasting station goes into the Air Force's "Hero Test Flight Squadron" to learn about the stories behind the test pilots...

"I'm really scared that because of this flight, what if the two good brothers really leave?" Li Lanxing from the Air Force test flight unit recalls a mission where a test pilot encountered a special situation.

Once we released the landing gear in the air, if the brake pressure didn't relieve in an instant, the aircraft could have blown a tire upon landing at such a high speed, potentially resulting in a nosedive. A nosedive means a crash with fatalities.

"The test pilot knows the consequences better than we do." At that moment, Li Lanxing was in the control tower, witnessing the out-of-control plane, and everyone's heart was in their throats. Then came the conversation between the pilots inside the cockpit.

Li Lanxing recalled, "The older test pilot said to the slightly younger one, 'I have no regrets, do you have anything to say?' It was very calm, like a last will. The younger one didn't speak, maybe both of their minds were thinking about something. Fortunately, the special situation handling was very successful. Test pilots are ordinary people, but they do extraordinary things."

Air Force test pilot team member Yu Jinwen said, "I can't imagine the torment they endured in those mere ten-odd seconds, nor what they were thinking. All I know is that in those brief ten-odd seconds, they managed to save the aircraft. If it had crashed, it might have led to the loss of this entire model, and possibly the efforts of one generation, or even two or several generations, would have been halted by this incident."

While testing the performance of the equipment, the pilot is also tested. Yu Jinwen is a military doctor who specializes in ensuring the physical condition of the test pilots. During his years in the test flight force, he spends time with the test pilots day and night. He often has to deal with various extreme situations

Yu Jinwen introduced: "At an altitude of over a meter, during this test, the pilot's breathing is in a reversed state. Our normal breathing involves actively inhaling and passively exhaling. However, in this situation, it is reversed. You inhale passively, with air being forced into your lungs, and you have to actively blow out to expel the air. Under such conditions, when the pilot disembarks, their eyes are bloodshot."

Test pilots must also complete various operations and handle emergencies in difficult breathing conditions. Yu Jinwen says that breathing problems are the simplest of all the challenges test pilots encounter.

"There might be some subjects that are like passing through the gates of hell. I need to go through them once to tell you whether my plane can do it or not. If it can't do it but was designed to be able to do it, then how do we improve it? That's what we test pilots are here to do."

Behind each model and series of numbers in the Meritorious Aircraft Park lies the dedication of generations of test pilots who have researched cutting-edge technologies, courageously pushed the limits of performance, completed the first aerial refueling flight, the first high-altitude cold weather flight, the first takeoff in strong crosswinds... These achievements filled more than ten gaps in the domestic aviation field.

Yu Jinwen said, "The value of our existence lies in ensuring that every piece of equipment we deliver allows our comrades-in-arms to accurately strike the enemy at first shot, to defend our homeland, our skies, and our peace."
