Rick Maschek who built the motor is here, and is an excellent sharer of
information, so I’m sure he’ll be by the list in the next week or so.
As to the list itself, there are few rules. Feel free to post a new thread,
ideally related to the topic of amateur rocketry. Expect it to go off
topic, but there’s always a good chance someone can address the question.
Please don’t reply to every unrelated thread with your personal hobby horse
of a concept.

Do you by any chance know what the case thickness and bolt sizes were? By
the way don’t know if this is the right place to ask, but is there some
explanation how this mailing list works precisely?

There was a picture of the end of the casing posted in the discussion
about the static fire on reddit, it was all there, with only a few of the
bolt holes stretched out.
That means that there was enough thrust to push the casing a few feet
deeper underground.

That’s more than the nozzle, that’s the back half of the casing separating…

The 12 inch S motor blew out the nozzle on ignition. I wasn't there, but a
few different videos have been shared around.
This is the best one I've seen: https://media.discordapp.net/attachments/

Heard about the CATO at FAR today - hope everyone’s OK and that the
setback proves minuscule.

We are static firing our 12" S-26,500 KNSB motor tomorrow...total impulse
355,000 Nsec.
If all goes well, it will be mated with our 10" for a 2-stage to finally
finish Sugar Shot to Space.
