Chinese Space Program

Yeah, it appears that someone fucked up when they did the pre-test calculations.

Edit: It would be nice if those two videos had English subtitles.

How do you even f.ck up with such basic things so badly?? I mean the load limit, the thrust and the rocket weight, these are the first things you must carefully calculate before you go ahead and start testing rocket prototypes...

The amount of miscommunication and lack of procedure that must've happened for a project of this grand size is insane.

Why the hell doesn't CNSA have any oversight on private projects? Americans love to exaggerate the amount of Chinese state involvement in everything, but for some messed up reason there's no involvement in this case at all.

This catastrophe is not just SP's fault, it's also the fault of the entire Chinese Space Programme in general.
 
It seems like perhaps they were rushing the test and intentionally used a marginal test stand for the load? *IF* the load tolerances in the above posts were accurate, then it seems more like a conscious decision to throw caution to the wind and test to possible destruction, Elon style.

This first stage was supposed to then be used on the first Tianlong 3 launch this fall, destruction was not anticipated.

This was a "one off" First stage made during the transition from their old factory to their more recent one, it’s likely there will be a relatively lengthy delay before they can finish other, however they do have an almost completed Tianlong 2 that was supposed to launch this fall too, so it’s not impossible they still achieve an orbital launch this year.
 
@Michel Van : it´s a really bizarre design with all those elongated bolts with their heads tightened on the I-beam flanges. Might cling and clang louder than a Church pipe organ.

IMOHO, the maximum acceptable load could have simply been forgotten/confused b/w contractor communication and the launch team (something like max dynamic load Vs Max static).
 
It has just occurred to me is what Elon Musk's thoughts and observations are on this bungled Tianlong-3 static-fire test are.

“我们发动机太好了，性能太强了。”上述工作人员说。他还表示，火箭（意外）升空后，公司主动关机让火箭掉下来，“这是我们先设置好，它必须关机，都是有预案的”。

"Our engines are too good, the performance are too strong." The said staff member said. He also said that after the rocket (accidentally) lifted off, the company took the initiative to shut down the engine to let the rocket fall, "This is what we set up first, it must be shut down, all pre-planned."

Well, they're still boasting about the rocket's performances...

Thanksfully it seems it didn't start any generalised forest fire. The rocket falling on the hillside behind the city probably also helped reduce the damage due to the overpressure.

Well it looked like one engine failed/exploded on it’s ascent, but there easily could have been physical damage separating from the stand.

Scott Manley in his video indicates it appeared to have suffered both with engine failing violently damaging other engines causing a chain-reaction of failures.

They don't seem to have learned their lesson...
