Road to science and technology

"Xiao Wang, there seems to be someone on the clouds ahead!!!" The captain, who was communicating with the ground about the landing strip, suddenly became excited. Then he glanced at the radar and found that the radar did not display any target.

Civil aviation passenger aircraft generally have a standard configuration of two passengers, one captain and one co-pilot. For some long-distance routes, some companies will equip one captain and two co-pilots.

This plane was not on a long-distance route from the magical capital to the mountain city, so it only had one captain and one co-pilot.

The co-pilot, Lao Wang, was about thirty years old and a handsome man. He was making preparations for landing at the moment. He obviously didn't expect that the normally stern captain would make such a joke.

He smiled and did not look at the clouds ahead. While checking various instruments and equipment, he said: "Captain, this is an altitude of 8,000 meters. You are talking about what the clouds look like!"

The normal flight altitude of civil aviation aircraft is between 8,000 and 11,000 meters. When preparing to land, it gradually descends from this altitude, so this aircraft is already making final preparations for landing.

The clouds at this height are generally medium clouds, which are cirrus clouds at a height of 2,000 to 8,000 meters. Just like its name, cirrus is a thin, white cloud layer. Sometimes they join together to form a sea of ​​clouds that covers the sky and the sun.

As is the case today, planes are landing through clouds.

"Damn it! He seems to be a real person!" The captain shouted at this time, his pupils soared, and then he made a decisive decision and immediately applied a small amount of force on the rudder pedals with his front feet.

If the radar does not display, then it is a test of judgment.

He was not allowed to think too much now, because according to his judgment, the plane was only about a thousand meters away from the target at this moment. Because the sky was clear, the air quality was excellent, and there was an obviously different color in the white clouds, so he could see an outline even from a distance of more than a thousand meters.

The aircraft has now entered the stage of preparation for descent, so it has dropped from the normal cruising speed of more than 900 kilometers per hour to 725 kilometers per hour.

In other words, he still has less than 10 seconds to react.

If he didn't react, the plane would hit the enlarging figure in front of him in eight seconds.

He no longer had time to think about why someone could appear thousands of meters above the sky, nor did he have time to wonder whether Xiao Wang believed it or not, because if he continued to wonder, the plane would hit him.

Regardless of whether it is a person or not, the plane must not hit it upwards.

"The target is not big. As long as the plane is slightly offset, it will not hit!" Three seconds later, the captain stared straight ahead and saw the target gradually drifting towards the right window, and he breathed a sigh of relief.

It was getting closer and closer. After two seconds, he was really stunned because he really saw it this time!

There is someone on the clouds!

The captain pinched his thigh hard, it hurt!

"Captain, Captain! Am I right? There was someone on the clouds outside just now?" At this time, a surprised voice came from the co-pilot next to him.

The moment Xiao Wang raised his head just now, he happened to see a figure passing by on the clouds in the direction of the window corner.

"That's right." The captain replied concisely.

But his mind was also screaming that it was impossible, and he was not as calm as he seemed on the surface.

The first mate also saw it, so it couldn't be an illusion.

"Skydiving? What bastard is risking his life by skydiving on the waterway!!!" Xiao Wang only saw it once, so when he saw the captain's answer and made sure he was right, his first reaction was that someone was skydiving.

"Modu 8421 calls..."

Xiao Wang was about to call ground air traffic control, but was interrupted by the captain before he could finish speaking.

"No need to shout, it's not a parachute jump." After saying this, the captain did not continue to explain, but continued in a calm and unquestionable tone: "The runway has been cleared, and we are preparing to descend. All crew members are ready!"

"Understood!" Xiao Wang, who was in the co-pilot seat on the right, replied. Although he didn't know why he wasn't parachuting, now was really not the time to talk about this, because there were more than a hundred passengers on the plane, and he had to get into work immediately. to ensure the safety of all passengers.

After a while, the altitude gradually decreased, and after a period of mist and thick clouds, the plane passed through the clouds smoothly.

At this time, a cry of surprise sounded from inside the cabin.

"Oh my god, Xiaolan, look, there's someone on the wing outside the window!!! Cell phone, cell phone..."

The girl in the window seat pushed her friend next to her, then hurriedly took out her phone from her bag and quickly unlocked it with her fingerprint.

During takeoff and landing, flight attendants ask you to turn off your cell phone or turn on airplane mode.

The girl's cell phone was not turned off, it was just turned on airplane mode.

The girl she called Xiaolan looked like she had just woken up, and said in a daze: "Sister Wei Qin, what are you talking about in your sleep? Hasn't it landed yet? Why didn't you say there was a ghost outside? Well... it's landing. It will be there in a while, let me sleep for a while..."

"Wake up, there is really someone, look, look, wing on wing, wing on wing... there is a person standing on the wing, wake up! I'm not lying... Come on, come on, pinch me!" Wei Qinmei, who was sitting by the window, didn't look back. She held her cell phone in her right hand and put it against the window, and shook Xiaolan on her left vigorously with her left hand.

"Ah! It hurts me to death. What are you doing!?"

Wei Qinmei, who suddenly felt a heavy blow on her waist, cried out in pain. This damn Xiaolan was so cruel that her tears almost overflowed.

"Didn't you ask me to pinch you?" Xiaolan was speechless. She looked out the window drowsily, "What are you taking pictures of? It's not your first time flying. What's there to take pictures of..."

As she spoke, she suddenly became energetic, and then her pupils suddenly dilated.

"Is this... a person? There is someone on the wing! How is that possible? Sister Qin, pinch me to see if I'm dreaming!"

Shocked, Xiaolan rubbed her eyes, thinking that she was not asleep and had made a mistake. However, when she straightened her body and looked out after doing this several times, she still saw a person standing on the wing of the plane.

At this time she was really shocked.

When people are shocked, the excitability of sympathetic nerves generally increases, and the main functions of sympathetic nerves are to dilate pupils, accelerate heartbeat, constrict skin and visceral blood vessels, dilate coronary arteries, increase blood pressure, dilate small bronchi, weaken gastrointestinal peristalsis, and weaken bladder walls. Muscles relax, saliva secretion decreases, sweat glands secrete sweat, arrector pili muscles contract, etc. Therefore, pupils should generally be dilated and hairs stand erect.

It will shrink when you are disgusted, tired, or troubled.

"Ah! What are you doing?" Xiaolan cried out in pain as she felt a cramping pain in her thigh.

"You asked me to pinch you. Don't worry about it. There's someone on the wing. Get your phone and record it and post it to Moments..."

"This... I'm not dreaming. This can't be a cultivator."

At the same time, there were exclamations from several other window seats.

"Damn it, is there really a world of cultivation in this world?!!!"

"Oh, Ah Dong, I have decided. When I get off the plane, I will go to Baiyun Temple to become my disciple!"

"Go to Baiyun Temple, Wudang Mountain, Longhu Mountain!"
