Earlier quoted context omitted.

A pirate space organisation that gets the air space over them closed by the government.

Air space over international waters can be controlled by a government?

"We fly our rockets from the military firing practice area ES D 139 in the Baltic Sea, 20 km east of of the Danish island of Bornholm. It spans 70×35 km, and are opened to us by the Royal Danish Navy for the launch time window. The Danish and Swedish authorities are very helpful, and close the airspace above for airtraffic in the hours of the actual launch."

Why aren't we all doing this! Isn't this the dream of everyone who ever built a model rocket?

Feasibility is the major contributing factor. Time, Space and Money are hard to come by. Then of course there is the red tape from the respective government involving permission for a very costly hobby. Then, the easiest to acquire, knowledge.

Also regulation I’m not entirely sure how many countries would let you build what amounts to at least an intermediate range ballistic missile in the back yard.

I’m actually wondering how did they get by with the multiple missile technology non proliferation treaties out there.

One of the founders of Copenhagen Suborbitals are the now infamous Peter Madsen https://www.theguardian.com/global/2018/jan/07/copenhagen-ki...

Just curious: what's the purpose of your post ?

I was tangentially involved in the Nexo II launch. Alexandru Csete (author of Gqrx) used my GNU Radio DVB-S2 transmitter code to send live HD video from the rocket. https://www.youtube.com/watch?v=uwSYv8eVQqQ https://www.youtube.com/watch?v=WYF8Am-lt20 https://www.youtube.com/watch?v=uqwJu6cSBW4

Ron, both of you are famous in free software and amateur radio communities due to your work, so thanks again. I have some doubts though regarding the safety of manned launches here. Seems like a serious issue to me and I hope it's not treated lightly.

I had doubt on manned amateur launch too, it is quite likely that the safety requirement would not be as strict as NASA due to funding issue.

Nevertheless, space flight requires bravery, some people might be willing to risk their life on the rockets, cant blame them, space is too much to explore.

Aye, sure, he might be a murderer.

But is there any evidence to suggest his murderous behavior makes him a poor engineer?

I do agree that it is good he left the project long ago, though.

I'm curious how a volunteer organization will achieve the culture and technical maturity to make human rated hardware without a high probability of a horrible death. Think about all the conditions in a long chain of events that must all go right, in a launch, to avoid cooking, freezing, squishing, cratering, asphyxiating, poisoning, exploding, or drowning your crew.

After decades of practice, NASA ended up under 1:100 odds of mishap at the end of the Shuttle program, with some estimates at 1:25. It would be fair to say all space programs need to go through a learning period where you blow a lot of things up and discover all the failure modes. SpaceX ate through several billion dollars on this path, before dialing in their launcher reliability, and they still don't think they're ready for humans.

How will CS do all this learning and get everything right?

Maybe that's not their primary goal? People have taken horrifying risks to push frontiers throughout history. The Oregon Trail claimed an estimated 21,000 lives.* Perhaps they are willing to accept a higher risk of death?

*Though, despite the horrific toll, the final odds of death on the O.T., once the dust had settled, were about 5% to NASA's ~4%.

My impression from afar is that they are far from strapping themselves inside a rocket, no matter what, like that flat earth guy. The manned part seems to be more like an aspirational goal than a fixture that will push all compromise elsewhere.
