Looking at the real-time comments and barrages on various platforms, Tang Chao felt that this live broadcast was very successful.

At first, he didn't have time to watch, but after the shuttle departed, he naturally had time.

Commercial use, riding experience or something, of course, he noticed that the reason why the original design was a bit inconsistent with human riding habits was because this thing was not designed by humans.

Although his order is to design a flying machine that humans can ride, the little green man of Kanxing is not a human after all, even if he wears a mecha, so his way of thinking is different from that of humans.

They used the human data provided by Tang Chao, plus some research on Tang Chao's own behavior and habits, and this type of aircraft was completed.

Thief fast!

Tang Chao also took a test ride in Kanxing, and he felt ...... It's okay, but after taking it to Earth to make it and handing it over to a professional service team for evaluation, they found a bunch of faults.

Oh, there are no major problems in aerodynamics, flight control, mechanical design, etc., mainly in the design of the service cabin and cabin.

The service pod is the transition section that connects to the interface, where things like food, drinks, towels, and things like heating and cooling are there.

After the evaluation of the professional team, problems such as unreasonable structure, inconvenient use of heating port, oversized cabinet door, and overly strong adsorption device were found.

The cabin is almost the same problem, but in the overhaul of 4 seats to 8 seats, these problems have been changed.

The biggest change in the appearance is probably the viewing window on the roof of the cabin, which has changed from 4 large to 8 slightly smaller ones, and in general, the window opening area has been increased.

In terms of the technology currently mastered by the Navigator company, these are not problems, so after a major overhaul, the appearance has not changed much, but the "Dart X" can also be said to be decarburized and reborn.

From an orbital shuttle that aliens thought was suitable for human rides, it has become an orbital shuttle that is truly suitable for humans and can be operated commercially.

The act of having the shuttle pilot recite a technical term step by step is also part of the commercial operation, in fact, the astronaut does not have to say anything, because the intelligence of the shuttle is very good, and it is basically ignored by pressing a few buttons.

The reason why the two pilots are said this to the camera is to make the passengers who may be riding in the future feel safe and feel that everything is under human control.

A sense of security is very important for passengers, and if they don't feel safe, no one will ride on the shuttle.

The sense of security comes from all aspects, and the control password is one thing, so that the pilots who are extremely expensive and professional in training are on the same aircraft as them, and passengers will also feel safe.

So Tang Chao copied these passwords from Kan Xing.

Now looking at people's comments and barrages, it proves that he did the right thing.

In the sky, the "Dart X" continued to accelerate and fly, and after the thrust was fully opened, the two pilots could already feel the obvious pressure and vibration.

"Du Kangsheng, how do you feel?" Tang Chao said into the microphone.

"Commander-in-chief, I feel good, I move freely, unaffected, and the G-force I feel at present is greater than the take-off state of a civil airliner, but far less than the description of the state when the manned spacecraft takes off." Du Kangsheng replied with a straight look.

"What about Li Yuling, how do you feel?"

"Commander-in-chief, I feel good too......"

The answers of the two are also broadcast live in real time, don't look at their words, but they also probably give a ride experience.

It is larger than the G-force of a passenger plane taking off, but less than the G-force of a manned spacecraft.

Of course, they haven't taken a manned spacecraft, hundreds of millions of people at a time, and they don't have the money to let them do real machine training.

However, although they have not flown in manned spacecraft, countries that have achieved manned spaceflight will record mission descriptions and compare them with the overload status of normal training.

So basically, this state is already bearable by ordinary people, and it is the kind that does not need to be exercised for a long time.

After all, tourists are here to travel, and it is impossible to train here for half a year.

This Tang Chao has been personally experienced, although it was Kan Xing a long time ago.

I didn't feel particularly comfortable at the time, but it was okay, his physical fitness at that time had not been "upgraded", and he could basically represent an ordinary earthling.

If he can bear it, then ordinary earthlings can also bear it.

And the current "Dart X" has undergone several humanized upgrades, and the ride comfort has been improved by at least 40% compared to the original!

Very good!

The speed of the shuttle is still accelerating, but the fuel consumption is faster, and the ring-plug engine is still a pure rocket engine after all, and once it is driven, it is a bottomless pit.

Now that it has reached a critical moment, Tang Chao no longer asks questions, he, the staff of the control center, the two pilots, and the audience in front of the live broadcast have become careful, and even their breathing is much slower.

Only the speed of the shuttle shows that it is constantly changing.

When the shuttle's flight speed reached 27,000 kilometers per hour and the altitude reached 200 kilometers, Du Kangsheng and Li Yuling suddenly felt that the whole space seemed to be quiet, and their bodies were relaxed.

They "lightened", and the mascot-like Q version of the "Dart X" plush toy floated up.

This is the flight speed of the shuttle basically to the first cosmic speed, and they are weightless.

The plush toy that floats up is the "Zero Gravity Indicator".

"The engine is turned off at one time, and it enters inertial flight to make attitude adjustments." Du Kangsheng was very excited in his heart, but he still said calmly on the surface.

"Understood!"

Li Yuling did so, and clicked the six engines off in three times in the first order.

"All engines shut down at once."

At this time, the shuttle is in the shadow of the earth, and the fuselage slowly rotates by inertia, and through the porthole in front of them, the two can see the little lights below, which is the western hemisphere at night.

Turning a few more angles, their orientation was aimed at the darkness and depth of space, and the sea of stars showed them an unimaginably magnificent scene.

Without the astigmatism of the atmosphere, they could see more beautiful things, the shining stars, like gems set in the starry sky map.

They can even "feel" that there are space nebulae composed of various colors of dust, gas, debris and other polymers in the middle of the stars, and these nebulae of different colors are also connected, plus those shining stars, and finally connect to form a magnificent galaxy.

This image was transmitted all over the world through hundreds of millions of large and small screens, and people were shocked by this beautiful scene.

I don't know if the stars are giving face today, or the universe has also been upgraded, or the latest lens imaging system is powerful, and the starry sky is particularly beautiful.

"It's so beautiful! Why didn't you think it was so beautiful before? ”

"Yes, I used to watch all kinds of space cameras in the dark, but now I feel like a gorgeous starry sky in an electric science fiction movie!"

"it, cow batch!"

"Upstairs is really straightforward, but I also wondered, is it because of the arrival of aliens that human beings have awakened some strange abilities, such as being able to better discover the beauty of the starry sky?"

"Hey, don't say it, although it's quite poetic, but there is a bit of truth when you think about it, maybe this represents the preparation of human beings to go to the stars from the spiritual level."

"I think it's also the case, if humans want to become an interplanetary civilization, it is not enough to only upgrade technology, and their mental state must also change!"

"It's so mysterious, it's also designed to be soul and spirit, maybe it's just that something in the universe exploded, and the flash caused the universe to be brighter?"

", what you said is even more mysterious, if something explodes and can dye the entire starry sky with a layer of light, then we are not far from death."

"Hey, that's not necessarily, the light we can see now is ancient light, those places are tens of thousands, hundreds of thousands of light years away from the earth, and when the power spreads, human beings may have stopped eating a long time ago."
