“Heavenly night! It’s just a fantasy!”

Old Mr. Ding was chattering, but he was clearly so serious!

“Just want to find the location of this Li Sei paste through a photo, this young man, the ambition is too big!”

“I have been in the field of evidence for so many years, and I have never seen anyone dare to think like this!”

Mr. Ding, I don’t know why.

Unexpectedly, he was angered by Ning Chen’s behavior.

Perhaps, it was because a problem that should be very serious and cautious in his eyes was actually solved by Ning Chen with such a childish behavior?

So, the old gentleman turned out to be a little angry.

Everyone, listening to the old gentleman, is like listening to the book of heaven.

Completely incomprehensible.

However, at this time, they know one thing.

That is, this moment.

This old gentleman was talking to Ning Chen!

Only this old gentleman, and Ning Chen, knew what they were doing and talking about each other!

“Flight altitude! The flight altitude cannot be determined, how can you be so hasty to think that the plane in the picture is taking off or landing?

Suddenly, the old gentleman’s words came to an abrupt end.

He suddenly thought of the live broadcast of this anchor he had just seen.

This anchor, while observing the silhouette of that plane.

First of all…… The details of the tail of the aircraft were first zoomed in.

The tail of the plane … There are white trail lines!

Suddenly, Mr. Ding, he felt goosebumps rise on one side of his body.

“Trail line…” Mr. Ding began to pacing around the conference hall, muttering under his breath.

Start talking to yourself!

Others, completely dumbfounded.

But they did not dare to speak, did not dare to move, did not dare to disturb in any way.

in the photo.

That plane, in the night sky.

On both sides of the plane, there are two faint white marks.

Such white traces.

Known as the “wake line” of the aircraft.

The tail line of the aircraft is very common.

Commonly known as aircraft cable.

Visible clouds formed by water vapor emitted by jet engine engines.

What Mr. He Chu thought of was the unknown details of the trail line.

The exhaust gas emitted by the engine is quickly condensed into small water droplets or small deposits into ice crystals when the air is cooled.

This is the basic principle of the aircraft wake line.

“If the plane has a trail line, there must be a condition!” Mr. Ding said to himself, as if to speak to others (although others had no idea what he was talking about).

“That is, it has to be in a low temperature environment at a higher altitude!”

The old gentleman’s face suddenly turned red.

He got excited.

“Generally, it needs to be around 8,000 meters above sea level and the temperature is as low as minus 40 degrees Celsius to form such an aircraft trace. ”

“Because in essence, it is carbon dioxide and water vapor after the combustion of hydrocarbon fuels. ”

“So it must be in a low temperature environment of at least 8,000 meters to form!”

“Ahhh… This young man, he has already analyzed this detail in his heart, wonderful!” said Mr. Ding aloud.

The entire conference hall was filled with his voice and pacing back and forth.

“Aircraft, below this altitude, the trail line cannot be formed!”

“After this altitude, the aircraft enters the stratosphere, and it is no longer necessary to urge the engine to release exhaust gases!”

“At this time, on this photo, the plane in the night sky outside the window has wake lines on both sides!”

This plane must have flown over the location of the picture at that time in a low temperature environment at an altitude of about eight kilometers!”

“More than eight thousand meters…” The old man closed his eyes and thought, and then suddenly opened his eyes, “Help me check the maximum climb rate of the Boyne 747, how long does it take from takeoff to climb to this height!”

Someone next to him got an order, and I don’t know why I want to check this information, anyway, I just started to check.

The results were quickly found.

“The maximum climb rate of the Boeing 747 aircraft is 10.2 (m/s), and even if the plane keeps rising at this speed, reaching an altitude of 8,000 to 10,000 meters, it will take at least 1,000 seconds, or more than sixteen minutes. ”

“But this kind of large passenger aircraft, it is impossible to always rise at the maximum rate of climb from the beginning of takeoff, so the time to fly to an altitude of 10,000 meters is longer, generally taking about half an hour…”

So you should look for flights that depart half an hour early!”

“It’s night in the photo, so the departure time of this flight is almost night!

Soon, the results came out.

“Mr. Ding, there is no information on this…”

Old Mr. Ding’s eyes widened, “Impossible! How could it not be?!”

“However, there is information about take-off at 13:05. ”

“13:05??” the old gentleman was taken aback.

How, is it 13:05??

Suddenly, the old gentleman’s whole person froze.

He grabbed the piece of paper on the table.

Numbers previously noted above:

CNMU9201305!

The last four numbers, 1305!!

The old man took several steps back, “Where did this number come from?!”

“It was before, Ning Chen, that is, the light picker in the live broadcast room, he suddenly wrote it down in the hotel earlier tonight…”

“What??? he turned out to have already written down this point in time???”

Old sir, it’s like seeing a ghost.

The others, with a confused look.

There is no know at all what is really happening now.

Everyone felt the abnormality of the old gentleman and looked at him together!

The old gentleman’s face turned red.

His eyes widened suddenly, as if his eyes were split!

The mouth, slightly open, the lips moved a few times.

Suddenly, the old gentleman closed his eyes.

Then, open it again!

The old gentleman’s mouth slowly opened.

Head back.

Director Liu was taken aback, thinking that Mr. Ding was going to faint!

I was about to step forward to help, but I heard a while,

“Ha-ha-haha-haha…”

The old man laughed up to the sky.

Everyone, stunned.

Director Liu knew Mr. Ding more than 20 years ago.

From then to now, the two of them have known each other for more than 20 years.

Old Mr. Ding, well-educated, is a gentle old intellectual, and he has always spoken in a gentle manner, not even loudly.

And today, for the first time.

Meet this old gentleman.

Laughing so heartily, even – presumptuous!!

After laughing, the old man said directly.

“Awesome! Awesome! It’s a genius! Genius! This kid named Ning Chen! It’s a genius!!”

Others.

See this reaction of the old gentleman.

All stunned.

And tonight, what happened.

Everyone, at all, did not understand at all!

However, they understand.

This moment, no one else.

It only belonged to Mr. Ding Xiangdong, and the young man named Ning Chen.

It’s just an airspace conversation between the two of them!

And even more terrifying.

In this conversation.

Old Mr. Ding’s level of existence, unexpectedly!

They were all left behind by this Ning Chen!

“Mr. Ding, what the hell is this…” Director Liu, with a confused expression, stepped forward and said.

Old Mr. Ding, his face was rosy.

But he suddenly raised his hand.

“I don’t want to explain to you, explain, you don’t understand. ”

Sighed, “I can only say that the afterlife, fearful, unexpectedly, there will be such a young man who throws me away from such a long distance, it is really admirable.” ”

Listening to the old gentleman say this, the others were even more confused…

“Say nothing else!” the old man looked at the others.

“Did you just see the building he ended up locating on the map?”

Everyone else looked at him.

Still puzzled.

“That building, that is, at that time, the specific location of the video shooting by Li Sei!”

This statement came out.

The whole audience fell into the cold.

The birds fell silent.

Long.

Everyone’s eyes widened.

“I know, you must be confused, how the hell did he get there!”

“But it doesn’t matter anymore, what matters is that I can be sure that he is right!”

“That’s enough!”

Liu Bureau, paused, stepped forward.

“So, what does all this mean?”

Old Mr. Ding shook his head and also paused, “Anyway, this Li Sai paste has a big problem. ”

Liu Bureau only smiled bitterly.

Suddenly, in the conference hall, the voice of a policewoman came:

“Old Mr. Ding, you mean, Ning Chen, determined the location of this Li Sai ointment?”

Everyone looked at Zhao Mengmeng.

Mr. Ding nodded, “That’s right, this process of determination is complicated. ”

Zhao Mengmeng was stunned, and suddenly, a terrible thought rose from his heart.

“Then…” Zhao Mengmeng looked at the others, “Just now, Ning Chen suddenly left the hotel, and it seems that he should have left directly. ”

“He…” Zhao Mengmeng, suddenly felt that his whole body was cold, “Will he, is it direct, to go, the location of that Li Sei ointment?”

As soon as these words came out.

The audience was silent again.

Everyone, on their backs, rose a layer of chill.
