Apologies for coming off like I was giving bad advice to people who may not
know better. I could be wrong, but the advice I gave was with respect to a
young man going to the Air Force Academy next year and Liquid Hydrogen
being a vast Research Wasteland, ignored and unexplored. I'm still baffled
by this Hindenberg Syndrome, when a normal discussion on this group is
about all kinds of Oxidizers and Fuels being mixed together to make solid
rocket motors. Motors that once mixed remain Dangerous from then on until
sometime after launch.There is a reason that the Vehicle Assemble Building
at KSC was off limits to Visitors during the Space Shuttle Program. I got a
tour of the VAB during the Apollo Program, it was great. But generally
speaking, Liquid Rockets are empty benign machines that poss no danger to
anyone until they are being readied for launch or a test. (Test Stands are
great, please ignore anything I've said about them being skipped or
unnecessary)
What i read into Christopher words isn't advocating for moderation, but
more like censorship. He brings it up in a thread about "Orion Abort Test
Failure" instead of just replying to the thread that was really bugging
him. Or, he could change subject line. I don't know what Christopher's real
problem is, and don't care, a personal attack over a differing opinion,
wtf. I care even less about what Christopher has to say. John's advice is
good, "scroll on by", me or Christopher, you are responsible for the words
you consume. Censorship is when someone else thinks they are responsible
for the word you consume.
Anton, yes, I'm trolling, trolling to get more young people interested in
using Liquid Hydrogen in their Rocket Projects, as Liquid Hydrogen is still
a vast unexplored territory. Fifty Years after it was essential in Landing
Men on the Moon.
Troll Alert..... Troll Alert......

Now, I've done it, I forgot to change the subject line, back to Orion.
Found these papers, found them to be interesting.

I wonder how much better the subsonic aerodynamics of SpaceX's Dragon
Capsule and Blue Origins New Shepard Capsule is compared to Orion. It
certainly can't be worst.

John, agreed he could totally ignore it. But you are also willfully
ignoring his other point: his (potentially bad?) advice affects other
people who may not know better. Perhaps that is why Christopher is
advocating for moderation here.
On the other hand, Craig seems to imply that once you turn 18 or 21 you
don't deserve the expectation of good/safe advice and it's on you to do
your own research. To me it reads more like him covering his own mild
trolling... but to each his own.

I've had enough of this guy.
I've been on this list for 10+ years. In that time I have posted once or
twice. Actually, I think the post yesterday was the third time. I mostly
like to see what other folks are working on with their hobbies. I've
enjoyed the commentary. Sometimes it borders on ridiculous. Sometimes
folks are just plain wrong. Others have arguments with others who are
being jerks. It's basically a normal amount of what one can expect from an
open forum on the internet. Except here we discuss rockets.
With that said though, I think it is worth pointing out that this guy is
practicing religious fanaticism to the most extreme with his self important
knowledge about launch vehicles and propulsion. Under no circumstances
should anyone hold onto particular ideas so much. Everything we do in
engineering is trade between something else. Forcing a particular
technology because it is your favorite is dangerous. Just like when he
told college folks to go ahead and use liquid hydrogen. You do us all a
disservice with your unwillingness to be a normal rational person.
Absolutely, you can use hydrogen safety. That isn't the point. Stating
that it is the only way to do rockets is a lie. A lie you willingly tell
over and over and over. And not just on hydrogen, but just about
everything else you repeat over and over again.
A lot of times over the years, I have watched people make fools of
themselves on here. People can be that way, but this guy just doesn't seem
to listen. Nor does he care. At one point someone asked him to tone it
down. He didn't. This an indication of being an asshole or worse. He may
have a mental disorder.
I've gathered enough to know that he used to work for NASA in some
capacity. I'm not sure, I haven't researched his credentials enough to
know his story (beyond the description he has just supplied us). But
considering how utterly wrong he is in armchair engineering (take the post
he put out about eliminating the sound barrier using what is essentially
pseudo-scientific engineering language), I have to question how long he
worked for NASA and how his departure from the agency unfolded.
You may very well be a guidance genius. Someone might have stolen your
BIG idea and used it. Or you are someone who was on the periphery of a
group of people working and you are trying to claim some ownership of it
here because you think none of us can go and find the real story about it.
I don't know. I do know though that you are far from a capable engineer in
other aspects of propulsion. You prove that with your lack of fundamentals
in engineering analysis.
Do the moderators have a method for removing people from the list who are
actively being a problem? Most of the things he says are so far off from
reality that it is mostly comical, but he does represent a danger to folks
who are still learning how this stuff works.

It's called "scroll on by". Or if you're sure that you never want to
hear what Craig has to say, add a filter to dump any message from him (it's
not terribly hard).
Otherwise, accept that he can be a jerk on the list, just you can be, or
I can be.
I've made posts where I said stupid stuff. I've made posts that were
ignored because they were stupid, or wrong, or silly. Once in a great
while, I've made posts and comments that helped.
I've also made acquaintances here that have broadened my vision,
broadened my knowledge. And I've learned that some are "one-note johnnies"
which can be good and bad. And I've met some that come across as seriously
flaming a$$holes, as I'm sure some have thought about me via this textual
medium.
TL;DR: Don't like what Craig posts? Ignore it. Don't like the list?
Leave, not cry for a mod to kick others out. Don't like where the
discussions go? Start one yourself.
