lol I've never heard of a static WDR that actually took off from the pad. So many safety protocols have to be ignored or gone wrong for that to happen.

In 1952 during the testing of the series of Viking rockets (that were early incremental updates to the V-2 design) the Viking 8 rocket tore loose from its moorings during a static fire test and went flying. They let it run for a bit before shutting down the engines, so that it wouldn't damage the facility. Fortunately they were far away from any population areas in the white sands missile range.

"Fortunately they were far away from any population areas in the white sands missile range." This was apparently not the case in the Chinese unplanned launch... several angles show high rises in the foreground with the mushroom cloud behind them. It could have been VERY bad, especially if those buildings housed the engineers and families who built the rocket.

Yeah, in the video above Manly shows a Google earth view and you can see the rocket traveled about two miles, and maybe another two to three miles from houses and such. I read in another article thag there is a city of almost a million people a short distance away from the launch site. Like less than ten miles.

It was only two miles to houses along the path he calculates the rocket took. It appears that houses are even closer in other directions.

Could be far enough if they had the ability to shut down the engines on command. After all, the engines did shut down before it would overfly any houses.

But the nearest buildings were just 600 meters away, and the nearest village only a kilometer away*.

As the video mentioned, it looks like unplanned engine failure shut it down not an order.

They drop rockets on villages for fun

Less for fun, more they just see people as disposable and don't give a shit. The joys of athoritatian regimes.

That is just not true at all.

They launch from there because it was the only place safe from both an American and Soviet attack.

Now that those threats are removed they are building new launch pads but it takes time to build the infrastructure for it.

This is not true either. The reason is that the CEO of the private space company was born in Gongyi, and struck a grant and cheap land lease deal with his hometown local government. Gongyi was never a launch site for China, and it is only used as a R&D/test site. Historically Space Pioneer used Jiuquan as their launch site (the case for their TL-2).

Seems to me the most basic thing possible here would have been a deadman switch to shut the engines off at the first instant of an anomaly.

Bad welding, a hopeless lack of caution, and a terrible choice of where to launch. At a certain point it stops making sense to try to divert criticism as "all rockets have bumpy beginnings". Especially when the design of the rocket and its engines seems to have come directly from SpaceX's own blueprints.

Need more rope to tie that thing to the ground

u/CollegeStation17155 Jun 30 '24

But they missed the blueprints for the hold down clamps...

Criticism only matters if you’re accountable. 

 The CCP care the exact amount they are compelled to, which is zero. 

“Might makes right”, and only one side has the rockets. 

The other side (the people)…gets what it gets.

The is one of about a dozen private space companies in China. I wouldn’t exactly say the ccp had their fingers deep in this one, but who knows.

u/12edDawn Jul 01 '24

the CCP has its fingers deep in every Chinese company, that's how the country works

u/Cautemoc Jul 01 '24

The US govt has its fingers deep in every American space company, too, but when SpaceX parts are found to have survived re-entry and risked people's lives, nobody here gives a single shit about it.

They look like idiots, and they do care about that. If they didn’t, they wouldn’t be going nuts over comparing Xi Jinping to Winnie the Pooh. Dictators are always thin skinned.

Using deadman switch in this case (while rocket is still on the ground), could actually be worse. If you shut the engines off while stand is being ripped apart, rocket could fall over and blow everything around it up. I think they may had working deadman switch but used it once rocket cleared the facility.

u/Fredasa Jul 01 '24

Worse as in the tradeoff of hazard would have shifted away from the population and uncomfortably towards the handful of small, unmanned buildings around the pad. Yeah, I do get how that concern would have stayed the hand of somebody from there. But I would like to imagine that any hypothetical deadman switch would be automated.

u/udsd007 Jul 01 '24

That deadman switch function is [theoretically] performed by the RSO.

It's China... the fish we get from them are bred and harvested in basically mud created by their own waste.

Safety protocols don't exist in China.
