This is deeply irresponsible by the CSNA and is a disaster just waiting to happen on the ground. Is it laziness on the part of their flight team or just crass disregard for others safety?

It is a calculated risk; perhaps similar to what have been done by the US and Russia when their space ambitions were at their highest.

Maybe; but the optics are terrible.

It was wrong then and is wrong now.

Ah, the good old “whatabout the US did it 50 years ago therefore we can do it today”. Also used to justify all sorts of atrocities, imperialism, IP theft, etc.

I also think there is a somewhat hyperbolic anti-China sentiment in the commentary on all of this. Plus a perhaps frustration at the US Space authorities on the lack of communication from their Chinese counterpart, something of course they themselves are entirely to blame for.

Anyway; the Chinese have done a few of these "uncontrolled reentries" now. All crashing into the ocean; so they are either very lucky or it is not so uncontrolled after all.

Neither. There just isn't that big a fraction of the earth's surface that's inhabited. You should regard this similarly to someone firing a gun into the air.

Chances of not hitting land after n completely random reentriees is (71%)^n. That drops fairly fast.

Reports suggest that they require only 3 launches in this configuration LM5B where the core stage falls back, for the construction of their station. They might have made the assumption that chances of damage due to debris is very low considering that only 3 launches are to happen with this configuration.

In case even if there is damage on the ground, there are treaties that govern the liabilities in case.

It would be interesting to know why they technically chose this particular way of doing it, but the discussion seems too hyperbolic for that.

Now that the design has been proved out, they're not going to stop doing it.

Regardless of the sentiments of the criticism, the fact is it’s irresponsible on the China part. You seem to downplay that fact. If you want to be balanced that’s the first thing you’d need to acknowledge. And no, it is uncontrolled. No questions about it.

No matter how small the risk, countries have to make plan, allocate resources, keeping track of the rocket’s path, in case it does happen. They can’t just pray. Spain briefly closed part of their airspace, delaying 300 flights. Who is responsible for that?

If you fired a gun into the air in the UK I'm pretty sure that a) You'd get in pretty serious trouble for it by itself and b) if you killed or injured someone that trouble would be significantly multiplied to the extent you'd end up in prison. I think it would be a manslaughter charge.

Is there anything wrong with being anti PRC?
