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 1:10…
It should be noted that, being strictly suborbital, both the challenges and risks are orders of magnitude lower than even a launch to LEO, and that unlike many space programs, they have quite a bit of prior history and information to draw on. I don't know whether this will be enough to reduce risk to near-NASA levels, however. I am curious as to whether those odds cited are of partial successes, safely-aborted launch…
It's by no means cheap or trivial, but a lot of technology have been democratized since the 60ties..
