(Let the dissing continue)

What "extreme weather conditions", exactly? This is New Mexico. Aridity is almost always desirable, because water vapor is the absolute worst, both for pumping down to vacuum and contaminating any instrumentation.

Did you see how when the nosecone punched through that membrane, it wasn't exactly on a perfect tangent? Definitely either some translational or rotational motion. The sensitivity of the payload's attitude to the exact mechanics of the release from the lever arm cannot be overstated, and the idea of an active, on-board attitude correction system capable of combating fluid turbulence at Mach 6 is just plain offensive.

I'm still trying to figure out what problem SpinLaunch is the solution to. Are the carbon emissions generated in producing the electricity required to spin up the arm and payload substantially less than the first stage of a conventional rocket? That's the only thing I can come up with. And I think the answer is likely a "no".

    Hey I know you didn't ask, and chuckle, well, this is certainly just a random thought I just had, sort of out of left field, almost! I'm like that, so spontaneous. Neurotic, in a way. But it's good! It works for me, and it's great for, like, big ideas, you know? And I'm a big big ideas guy. UGH, what was I gonna even say in the first place?! OH YEAH!! Look: It's easy to design for 10,000 g's, people just don't know it yet. $cout's honor.

or another good one is

    yadda yadda yadda and the data we took is fantastic! No, you can't see it.

4srsly tho: I want this to work. I would gladly eat my words.

It's not going to work.
