American military experts say: For the future of mankind, China should announce its mysterious aerospace technology.

  An American military expert wrote a small blog about China on the Internet:

  China shouldn't hide its plans for aerospace progress. Tengyun should cooperate with other countries in the world. Science and technology have no borders.

  In 2021, China people test-fired a very strange device, which is the military version of the legendary Tengyun project. This is a strange launch by China's military at the launch site in the west. This launch, China deliberately chose the departure time of the US satellite orbiting over China. Because of the time difference, our American satellites can't take pictures of its take-off and launch. China then released only a short video of only a few seconds. This launch should be very similar to the kind of Shenlong that we have seen launched by the Bomber Bomber before. This is not a strange product. The strangest product is its carrier. We have developed X47B and A carriers in the United States. After many experiments, we can achieve high speed, but none of them succeeded.

  This time, the recoverable landing vehicle developed by China people can be said to have surpassed our physical cognition. Therefore, we in the United States believe that for the progress of human space and the future of mankind, China should be asked to let go of the cooperation of this kind of aircraft, and the United States is willing to cooperate with China on recoverable suborbital aircraft. NASA has repeatedly declared that it wants to cooperate more closely with China in space. Therefore, I think China and the United States should cooperate in this field, which will be conducive to the further progress of mankind in space. Because this kind of recoverable second landing aircraft is very strange to any party, and China people have their own unique research ability and theory in hypersonic ramjet engine.

  Look at the comments of netizens from all over the world below the blog.

  An American said: This kind of thing is kept secret like a treasure in China. How can we get it?

  A European said: I think if you can steal a giant panda from China, you can steal this thing.

  An American said: Now all interceptors are invalid for this kind of space vehicle. It seems that there is a knife hanging over our heads. I think China people should use this technology to cooperate with us in the United States, so that we can compete fairly.

  An Englishman said: I think Americans are a little too nervous now. What's wrong with your technology? Can't you get a ground-borne recycler out? Didn't Musk make a rocket recycling?

  A Frenchman said: Forget it! That thing of Musk is just to take back the base. Only the base can do ground coordinate positioning, and the carrier on it is not allowed.

  An American said: This kind of thing is not particularly easy to study. I heard that it needs a hypersonic ramjet engine, and it needs to be converted into a turbine injector, plus an external high-temperature and high-pressure coating. This high-temperature and high-pressure coating is in the hands of China people.

  Another American said: In this way, our high-temperature and high-pressure coating in the United States is stuck by China people again.

  A European said: What a surprise! Americans began to beg the cooperation of China. How interesting!

  A Frenchman said: Don't forget the Wolff Act of the United States. Americans must never violate your bill.

  A German said: You are stupid. They are called bills. American bills are empty. If the United States wants to cooperate, it is a bill. If the United States doesn't want to cooperate, it is a law.

  An American said: Should we cooperate with China in this respect? This is very strange. Didn't you say to go to China?

  Another American said: What's wrong with NASA now? Take our taxpayers' money and get along like this day by day?

  At present, Americans are ambivalent. They want to cooperate in many aspects, but they also want to show their arrogance to their allies. They are afraid of losing face and the progress of China will not be stopped. Those people in America are really tired.
