The inspection team conducts the final inspection before flight.

"Report to the pilot, the inspection is complete, you can board the plane."

Lin Hangtian and Xiao Yu got on the plane.

"Check the instruments."

"The fuel gauge is normal, the airspeed gauge is normal, the speed gauge is normal, and the pressure gauge is normal."

"Data transmission is normal."

"The left and right ailerons are normal, the elevator is normal, and the rudder is normal."

“…”

"043 inspection completed, requesting take-off." Lin Hangtian said.

"043 can take off." The tower instructed.

The plane taxied and took off, and retracted the landing gear after a certain distance.

"Report to the tower, we have arrived at the designated test airspace."

"043, conduct airborne self-check."

"043 received, altitude 8000, speed 420, distance to the airport 80 kilometers, fuel gauge normal, airspeed gauge normal..."

"In-flight self-check completed."

"043, continue flying to the designated altitude."

"043 received."

The plane took off and reached the designated distance. Lin Hangtian said, "043 has reached the designated altitude."

"Self-check again."

"Got it. Self-inspection completed."

"Begin high angle of attack flight."

"receive."

The aircraft began to change its angle of attack (angle of attack), and the flight angle of attack continued to increase.

"45 degrees angle of attack is normal."

"60 degrees angle of attack is normal."

“…”

During the test with increasing angle of attack, the tower kept a close eye on the real-time transmission images.

[Warning! Warning! Stall warning! ]

The aircraft began to spin and the electronic equipment issued a warning.

A feeling of dizziness swept through their minds. Lin Hangtian and Xiao Yu kept counting the number of rotations and tried their best to stay awake.

"043, received, please reply."

"043 received."

"043, conduct recovery operations."

As the number of tailspins continued to increase, Lin Hangtian and Xiao Yu entered a black vision state, operating instinctively based on muscle memory.

【Warning! Engine stop! 】

[Warning! Warning! The engine is stopped, and the operation is invalid! ]

The test pilot remained calm and continued operating.

"043, please reply!" The tower commander's voice was filled with worry.

"043, received, please reply!"

"043, received, please reply!!"

"044, received, please reply!"

The atmosphere was heavy and everyone was silent.

"...043 received, trying to restart." After a while, Lin Hangtian's voice came.

【Restart failed! 】

"043, activate the backup power supply."

"I'll try again."

“Make sure you stay safe.”

"……receive."

【Warning, restart failed! 】

The engine stopped and the plane fell faster under the influence of gravity.

"043, prepare for parachute jump."

The test pilots were dizzy and dark, and they gritted their teeth as they operated, pushing the joystick.

The plane spun and fell, a buzzing sound began to appear in my ears, and the world gradually lost its sound.

The real-time picture began to show snow and flicker.

[Warning! Warning! Invalid operation! ]

"043, 044, if you hear me, please answer. Prepare to parachute! We can't try again!"

Lin Hangyu's putt went past neutral.

【Restart successful! 】

The airplane ceased its spin, recovered successfully and began to climb.

"Report to the tower, recovery successful." The breathing was heavy.

The two test pilots gradually regained their vision.

"043043, reporting status." The commander breathed a sigh of relief.
