At this time, the Changfeng District is not only crowded with people, but also almost less, and the streets or squares are crowded with people, all looking up at the sky.

The top of the building has the best view, and there are now many people on the top of many high-rise buildings in the commercial capital, without exception, who want to see the style of the Sky Blade Fighter.

As more and more people can see the figures of the returning fighters in the sky with the naked eye, the entire Changfeng area is a sensation and amazement.

At this moment, Menna controlled the Sky Blade fighter to slow down and fly low, passing from a height of about forty or fifty meters above the top of a building, and the sixty or seventy people standing on the roof of the building all carried various special cameras to follow.

Although the speed of the Sky Blade fighter has dropped to 124 m/s at the moment, the feeling for the people on the roof is still "whoosh" shuttling away, and the camera has no time to follow, after all, this is also a speed of more than 400 kilometers per hour.

After flying in the sky for a few seconds, the Sky Blade fighter made a maneuver that shocked the eyes and jaws of the audience under the witness of countless people.

Mona controls the Skyblade in a straight flight at 124 m/s, just as she turns off the twin-engine main engine system while all the vector secondary engine systems run at full power.

The Sky Blade fighter almost completed the 145-degree angle of the turn in an instant, and at the same time as completing the steering maneuver, Mena started the main engine system again, and the start of the light guide engine would not take even 1 minute like the traditional fighter, it started almost instantaneously, as fast as pressing an electric switch.

In this way, in just a distance of more than ten meters, the inertia speed of the Sky Blade fighter also plummeted to zero almost instantly, which was slow but actually fast, and the main engine system that started again, Menna drove the fighter to instantly increase its afterburner to the maximum thrust peak.

A young college student who witnessed this scene on the top of a building was stunned at first, and exclaimed: "My Mayer~~ I'm not mistaken, right? What just happened? The Sky Blade fighter actually made an acute-angle steering maneuver that was almost geometrically perfect? I can't hold Newton's coffin board anymore!! ”

Next to him, there was a forty-year-old uncle holding a video camera, and immediately said: "At first glance, it is high-tech, what is unscientific?" I think it's very scientific, what does it have to do with Newton? ”

The college student was young, although he didn't wear glasses, but his hairline was initially revealed, he looked at the fighter plane in the sky and said excitedly: "Objects in motion, especially high-speed aircraft, can't be bent at sharp angles, not at right angles, let alone sharp angles?" According to the momentum theorem ΔI=FΔt=m1v1 - m2v2, v1 and v2 are vectors, which requires a clockwise impulse I in the original direction of motion, and Δt is extremely short, then a force F is required, which tends to infinity, which is obviously impossible to do, contrary to the laws of physics, it is simply incredible. ”

The middle-aged uncle listened to his words quickly, although he didn't understand, he inexplicably felt that it was very reasonable, and immediately scolded him: "But the Heavenly Blade Fighter did it." ”

This made the college student speechless for a while, but it soon dawned on him that it was impossible to do it in theory, but in practice it was done, then it must have ignored some factors.

He quickly thought of what could explain the sharp angle turn that had just occurred with the Sky Blade Fighter, and thought of an example, which was billiards, which he had also played, and which occurred when the billiard ball collided with the edge of the table at an angle greater than 45 degrees.

This cool maneuver of the Sky Blade fighter may not have much tactical significance, but it can show the terrifying technical content of the Sky Blade fighter in front of people all over the world, if you decompose the speed of the fighter just now in the Cartesian coordinate system, it is not difficult to see that in such a short time to make an acute angle turn, there must be at least one component of the velocity in the same time to change to the opposite direction.

Of course, the Sky Blade fighter will not collide and bounce back like a billiard, and this force is provided by the thrust of the engine.

But how frightening acceleration does it have to be? Or how terrifyingly powerful is the thrust of the Skyblade's engine? And how terrifying is the technical content of the fighter's materials, body structure, etc.?

Otherwise, the sharp angle turn just made by the Sky Blade fighter will cause an overload that any fighter in the world today, including the F-22, will instantly disintegrate in the air.

"Wait, even if the body structure and instruments and equipment of the Sky Blade fighter can withstand it, but the pilot inside will definitely die, is the Sky Blade fighter a drone?" The college student was stunned again: "My God......"

It's definitely a drone, and he is extremely convinced that the fighter is unmanned, because it is impossible for a biological person to withstand it, and the overload generated by the sharp angle steering maneuver of the Sky Blade fighter just now is enough to instantly crush the pilot inside into a thin plate.

Only unmanned driving can explain it.

At the same time, after the Sky Blade fighter made an unbelievable sharp angle turn, the distance it flew out at this moment was already more than ten kilometers away from the college student.

It has left the Changfeng area.

Mona piloted the fighter plane and flew to the tallest building in the commercial capital, the Central Building.

"The Heavenly Blade is flying this way!!"

There are also many people at the top of this building, and when they see the distant sky, the outline of the fighter plane in the perspective is getting bigger and clearer, and the people here are also instantly excited.

The current altitude of the fighter plane is above the central building, and at this moment, Mona looked at the approaching building, and after being within a hundred meters of the central building, she suddenly entered an order.

"Switch to mecha mode!"

The speed of the Sky Blade Fighter in the air plummeted again, but the terrifying overload it generated in an instant only made the girl inside open her mouth and gasp lightly, and at the same time, the Sky Blade Fighter gorgeously unfolded the body transformation mode.

Everyone at the top of the building never dreamed of being able to witness the gorgeous moment when the Sky Blade fighter switched from fighter mode to mecha mode at close range within 100 meters.

"It's so handsome, so cool that I don't have friends!!"

"This is the "True Celestial Show" series!"

"As a member of the flower planter, I am really proud of this moment, and this prosperous world is as you wish!"

"I'm already so excited that I'm about to get goosebumps, is this really my flower planter's latest fighter? Are you sure it's not an alien fighter? ”

"Don't you see that flag?"

"Hey, look, the Sky Blade Fighter is looking at us, saluting us!"

“awsl~~~”

"The picture is simply picturesque~~"

At this moment, the Celestial Blade Mecha, which had quickly completed its magnificent transformation, was suspended in the air 42 meters away from the Central Building in a straight line, the main engine system had been turned off again, and the vector sub-engine was running, allowing the Celestial Blade Mecha to levitate in the air as if it were weightless.

The audience on the top of the building and even many people in the building stopped going to work, and they kept shooting through the glass, and the Sky Blade Mecha also showed itself to the world in a high-profile manner, attracting the attention of the world.
