Some speculation on China’s booster landing mitigation efforts.

As for the parachute, they might be trying to bring them down slow enough to keep them from rupturing the fuel tanks.
A cheap way to keep their people safe.
It would be better to launch from the coast like we do but they are afraid someone might see their secret stuff if they used the coast,

We can mount our high horse any time we want. We are American. And free.

The point of the article though was that China does not care about it own people very much or is just too stupid to learn from out 70 year old mistakes.
Either way they are idiots and we have learned.

To be fair, both of these apply to America, too:
it does take a certain _gall_ to operate like this.
You mean like blowing up entire islands with atomic bombs? Granted that they were isolated islands (that we surrounded with ships), but still.

A dirt farmer might swell with pride to see this futurist diversion from the mundane.
You mean like finding it in your field in the 1950s? I’d bet many American farmers, with visions of Tom Swift and his Atomic Airplane or Tom Corbett – Space Cadet, would have that reaction.

That doesn’t mean this is not irresponsible, but we do need to beware of mounting high horses.

Early US launch vehicles like Vanguard used Red Fuming Nitric Acid (RFNA) and Unsymmetrical Dimethyl Hydrazine (UDMH) as hypergolic fuel and oxidizer in the second stage. Is hydrazine toxic? You be the judge

and RFNA is just as bad

Don’t think I’d liking working in the pit crew at the Cape back then….

not sure if this is applicable, main engines vs boosters, sometimes , always. Manley say China uses both types of fuel. Either way, your points in the post are valid. https://twitter.com/DJSnM/status/1405915092072366086

I’m well aware of the consequences here, but my first reaction was LOL. Not the usual on your way to work.

The kid in me would think it kinda cool. If it weren’t toxic, I’d put it on wheels. Here-we are sue happy. There? A dirt farmer might swell with pride to see this futurist diversion from the mundane.

wash it down and auction it off to the world’s various museums.

it does take a certain _gall_ to operate like this. wow. no wonder they don’t do popular elections.

That’s a picture of a Chinese Landing Pad for their boosters. C’mon Man., give them a break, they have not yet been able to steal that SpaceX technology. Darn that Musk and his cyber hacking defense team!
