The fat uncle couldn't help but beam with joy, his eyes full of admiration, and his mouth exaggeratedly rounded into an o:

"Oh ho ho! No wonder your name is Ekaterina, little angel, great job!"

Saying that, the fat uncle gave Xiao Yuanman a thumbs up.

Immediately, the fat uncle started chatting like a veteran who had been on the battlefield, talking endlessly:

"While radio silence is maintained, passive detection equipment is turned on on the aircraft."

"The platform itself only receives signals, not transmits them."

"Radio silence is a basic tactic for low-altitude raids by the Air Force, Naval Aviation, and Army Aviation."

"It doesn't matter that the early warning networks in various countries around the world are getting better and better."

"In fact, implementing radio silence on the battlefield is still a very effective means of surprise attack."

"It has been used since World War II to this day."

"Radio silence is of great significance for concealing our combat operations."

Xiao Yuanman stared at Yuanyuan and listened very seriously.

Si Chen himself was also listening, and the three Wuzhi pilots behind him, disguised as bodyguards, also pricked up their ears and listened carefully.

The fat uncle got tired of standing, so he sat on the chair next to him, let Xiao Ping An sit on his lap, and continued:

"During World War II, there was a very famous battle."

“The U.S. military dispatched P-38 fighter jets to sneak attack on the plane of the island country’s navy admiral Yamamoto.”

"At that time, in order to keep the operation secret, the method they adopted was to fly at low altitude.

"Furthermore, radio silence is maintained between the fleets to avoid radar detection by the island nation's military."

"Prevent the communication between the fleet and the ground from being intercepted by the electronic reconnaissance equipment of the island nation."

"The result of this battle is that the American army achieved the expected surprise effect."

After the fat uncle finished speaking, the cabin became extremely quiet.

Xiao Yuanman seemed to understand but Xiao Ping'an didn't pay attention here anymore.

He slipped off the fat uncle's legs and fluttered forward to unseat the densely packed mechanical driving parts.

The fat uncle turned around and went to take care of the child.

Si Chen took the opportunity to whisper something in his daughter's ear.

The next moment——

"Grandpa An, if the radar system is so advanced, won't it be able to detect large aircraft?"

Hearing Xiao Niuniu's logical and rigorous inquiry, the fat uncle was shocked again.

Looking back, his eyes were filled with surprises:

"Ouch! You, a three-year-old baby, know a lot!"

Xiao Yuanman just wanted to correct the age issue, but after thinking about it, forget it, what does it matter?

There are many people who mistake her for a four-year-old.

The fat uncle stretched out his hands and patted them with a kind face:

"Little angel, come to Grandpa An!"

Xiao Yuanman looked back at her old father. Si Chen nodded, then she opened her hands and went into the fat uncle's arms.

"Come on, little angel! Grandpa An will teach you how to drive a transport plane!"

"Grandpa An, you haven't answered my question yet!"

"Hahaha!" The fat uncle laughed heartily again, held the child in his arms, and replied:

"Okay, okay! I'll tell you, I'll definitely tell you!"

"As far as the current radar level is concerned, there is one thing that cannot be avoided."

"Whether it is ground radar, shipborne radar, or airborne radar, most of them propagate in a straight line."

"Their detection range for low-altitude flying targets is often only more than 40 kilometers due to the curvature of the earth."

"Little angel, you should know, right? The earth we live on is a round football with curved arcs."

"Whether radar is detecting aircraft or missiles, it will be affected by the curvature of the earth."

"Therefore, once the radar detection range is exceeded, radio listening is often required."

"Then, we can position the large aircraft in the sky accordingly."

"When your radio is also silent, then the other party will naturally not be able to detect you!"

"Even if you enter the radar detection range, you are accidentally detected."

"As long as your big plane is fast enough and you run away after the sneak attack, the other party won't be able to do anything to you, hehe!"

After the fat uncle finished explaining, Xiao Ping An, who was fiddling with the operating lever, suddenly turned around:

"Grandpa An is great! Like it!"

As he said that, he also gave a white and tender thumbs up, showing that the warm man's spirit was carried forward to the end.

Si Chen:......-_-||

What I teach you is to learn "likes" deeply!

…

I spent two hours laughing and joking with the fat uncle.

When we parted, the fat uncle was reluctant to leave and waved goodbye:

"Little angels, come and play with Grandpa An tomorrow!"

Xiaopingan was very enthusiastic and said loudly:

"Goodbye! Grandpa An! I'll come and play with you tomorrow!"

After saying that, he put his fleshy hand on his mouth and blew a kiss to the fat uncle.

It made the fat uncle laugh again.

The aloof Xiao Yuanman also blew a kiss:

"Grandpa An, goodbye!"

The fat uncle responded very enthusiastically, blowing kisses to the cubs with both hands.

Si Chen vaguely saw tears glistening in the fat uncle's eyes.

The uncle must have been moved by the scene and thought of something.

Si Chen didn't know what happened to the fat uncle, and he couldn't easily inquire into other people's privacy.

Foreign countries are different from us. The relationship between children and their parents when they grow up is not as sticky as in our country.

It is almost non-existent for children to live with their parents.

Of course, parents can also worry less and do not need to help take care of their grandchildren.

The idea of ​​raising children to provide for old age does not exist in most countries.

Suppose, the fat uncle Antonov and the Antonov are the same thing.

So!

There is a high probability that the turmoil within the big family hindered the fat uncle's family happiness.

…

Si Chen held Zaizai in each hand, turned around, and left.

Xiao Ping'an pulled down the sunglasses on Si Chen's head, put them on for him, and said:

"Grandpa said you must wear sunglasses when you come to the camp, so that you will look powerful and domineering!"

Babies of this age are at the stage when their awareness of rules is initially established.

They pay great attention to the sense of ritual, rules, and territory.

Si Chen really couldn't hold it back and burst into laughter:

"Haha, hahaha!"

"Be serious!" Xiao Yuanman waved his hand and gave his old father a slap in the face, specifically in the mouth!

Si Chen couldn't smile immediately and his teeth were about to be knocked out, okay?

The two little guys took out the small sunglasses hanging from their breast pockets.

The movements are almost the same. Wear them at the same time, look up at the sky, and look cool and crazy.

During that battle, once you put on your sunglasses, no one will love you!
