Sadly that branch of Acme that went out of business after the lawsuits

No need to waste a stamp, we can use my replicator.

Y'know. I was just puttering around in my garage last
night and found a dusty dewar of room temperature
single-H above my washing machine, between a dewar of
liquid ozone and a bottle of deuterium-rich hydrozine.
It crosses my mind that we should build an engine and
start testing with it ASAP. A

Less than that; pressure ratio and are

Ok, I try...
No, SPL is not the Swiss Space agency. We even don't get a cent from the
government for funding yet. We are just a small experimental group of
(mostly) engineers beeing fond of loud and fast vehicles. SPL is still a
non-for-profit organization. We have a main sponsor, ARO TECHNOLOG

Your leaving is probably a substantial loss for ERPS, but I feel AUSROC
needs you too :-)
Good luck and a good ride home!

Well, my time in the USA has now run out. I fly back to Sydney this afternoon
It's been a pleasure working with you guys on the KISS series of rocket
vehicles.
I've enjoyed it very much - and I hope that I've been able to make a positive
contribution to the organisation.

Now that everyone has decided (I think) that they may comment on the Swiss
engine, does anyone have any comments on the test?
Besides my original comment on how pretty their machining is and how
nice it didn't warp, I must ask a non technical question. How do you manage
to get so much beautiful
