Let's hope no one tries to get detailed drawings of something else
that's even more classified so they can build a model of it....say a
P-80 or Sherman tank:

Before you criticize try to understand the world situation today. There are
many things we did years ago that are still beyond the state of the art in
some unfriendly nations out there, and we shouldn't be giving them a free
hand up. When Chinese launchers were used to place Iridium satellites in
orbit they needed help in orbital transfer techniques for launching multiple
satellites on one booster. The Clinton administration handed this away -
something we developed during Geminin days to support the Apollo missions.
Then a little bit later  they use these techniques in destroying an obsolete
communications satellite - a capability that would allow them to destroy our
satellite systems during a wartime situation. The Iranians are still trying
to get hardware and information to get their F-14s operational. Just cause
ours have been scrapped doesn't make theirs any less lethal. Technology
transfer over seas is a major and complicated issue, and the constraints are
not always obvious. Stealing American technology is a major goal of foreign
nations - one for military purposes and two to hand off to their companies
that are in competition with ours. Some of the later involves countries we
usually consider to be friends.

However, the specific ground for refusal related to defense articles.
The benefit a foreign power might get as a result of the release of the
drawings is not itself a consideration, and the defense article
restriction should not be used in relation to something that isn't one.

If the US government feels that certain information should not be
released because it could be used by a foreign power in a way that was
militarily significant, then it should enact a ground for the purpose,
if the legislature will let it, not bend another ground beyond breaking
point.

Almost anything that has to do with space vehicles has some military
potential, we are also in the beginnings of a new space race where our tax
payer dollars shouldn't go to helping the other guy. It seems to me we tend
to split hairs on legal nuances instead of just taking the practical view -
our tax payers paid the bill, our technologists developed it and it's
urs  - period.

The Freedom of Information Act was created to keep our government from
hiding things from the American public that they really had a right to know,
not for aiding foreign countries in their technological goals.

Certainly preventing the government from keeping secret things that were
merely embarrassing to the government was a goal, but once you talk
about things that the public have a "right" to know, it simply begs the
question of how far that right extends.

Freedom of Information Acts around the world have been created in a
environment where the default behaviour of executive government was to
keep things secret. In that context, they should be seen as creating a
right to know everything except those things for which there was a
compelling need for secrecy. To the extent that the legislature
considers the right not to be that wide, it can say so. Until it does,
the executive should implement the law as it's written, not as they'd
like it to be written.

data in them on the sci.space.history newsgroup recently.

This is the result of people (like you) not knowing the difference

Like doing a "Grand Tour" mission to the outer planets for example.
Unfortunately the planets aren't going to line up that way for a century
or two to allow someone to try that again via gravity assist, and by
then even Tahiti is going have the ability to do it.
I assume the big problem is the RTGs on Voyager. Unfortunately, the
Soviets used those on their remote weather sensing stations along their
polar shores, but between the time USSR fell and modern Russia emerged a
few years later... and they got around to checking up on them
again...most of those RTGs had mysteriously vanished somehow.

One thing you will find out by studying the history of espionage over
the past 200 years is that everyone was infiltrated by everyone else to
a degree that they never even suspected in their most horrible
nightmares - to the point where the US could decode Japanese diplomatic
intercepts pre-WW II faster than their own diplomats could, and the
Soviets were hard pressed to get the stuff they received from their
1940's-1950's spies in the US atomic weapons program translated into
Russian at the rate they were receiving it on a day-to-day basis.
There were two brilliant ideas for countering this; the first was used
by Kelly Johnson of the Lockheed "Skunk Works" when the they were
designing the F-117:
A.) There are around fifty people involved in this whole program who
actually know why the F-117 looks like that...by the time it got to the
production floor, the people who actually built it knew exactly how to
make those particular angles on it to those particular tolerances, but
had no idea why that was important, because we burned all the papers
concerning that before we put into production.
Or:
B.) The B-2 generated around 10,000 pages of paperwork per day from the
start of the program, and topped out at around 100,000 pages per day
when it hit full speed...which means if none of that paperwork was
classified "Top Secret", anyone  trying to figure on what we were up to
would have been like someone looking for a diamond in a coal deposit,
because around 99.99% of it was completely worthless from espionage
purposes, and they'd never know what was important or not.
Luckily, we were smart enough to mark select parts of it "Top Secret" so
that Soviet spies would know where to find the good stuff.
This was highly successful in keeping the aircraft's design concepts
secret, as they had a pretty much identical design ready to go by the
time ours entered service, except that their intake and exhaust design
looked smoother than ours. :-D

Reminds of a time I was working on a UK military software project. It
was all secret, at least to the extent that we weren't meant to talk
about it.

Yet many of us felt that the best thing we could do to advance the
security of the UK would be just to hand over the entire source code to
the Ruskis. The reasoning was that it was such a dog's breakfast that
they'd waste a huge amount of skilled technical resource trying to
understand how it worked (which it largely didn't).

You've got to understand the Russian mindset...
AW&ST: "Rumors hint at new US superweapon."
Time: "Rumors of new US superweapon exaggerated."
AW&ST: "New superweapon uses antimatter as key component."
Newsweek: "Time magazine in error; new superweapon is impossible."
Classified report to Soviet Politburo: "America develops new
superweapon. Uses antimatter as key component; official denial  in
state-controlled American media proves its existence." :-D

And the Soviets apparently weren't above trying the same trick right
back... it seems like the only explanation for the book "Psychic
Discoveries Behind the Iron Curtain". (Of course, proving they're such
an open society that they share their secret military research with
us... and encouraging superstitious belief in the West... also has a
plus side.)

Of course, I've noted that computers are so powerful today - even the
ones with the little 8-bit processors - that it's relatively trivial
to produce truly indecipherable ciphers. "Obviously", the NSA budget
is just a front for studying a crashed flying saucer!!!

But it seems to me the term "state of the art" refers more to
technology infrastructure than simple vehicle drawings.

Many times the services, especially the Army, owns the drawings to
weapons systems it buys.  Then, it can give them to another company
when the system comes up for replacement orders, and someone can
underbid the original developer.  But that frequently brings up
problems. Even with US companies, there are lots of processes that are
not included in "drawings", and the new company finds it very hard to
really produce weapons at cheaper prices, because they have to develop
the processes within their own company now.  And, frequently the first
lots from the new manufacturer have a LOT  of qc bugs.

I think the same thing is true between companies.  The real secrets
are not in the outlines of parts on the drawings.  Most countries have
machine shops and machinists who can make parts to prints.  Yeah, they
could make a Cessna  172 with factory drawings.  But items that
require fancy metallurgy, composite parts, chem milling, fancy
electronics, etc. are likely not to be easily produced.

Selling plans to a weapons system is not the problem- selling the
process technology is what is the problem.

I saw a video recently of someone claiming that they could run their welder
on water. You see, they use electrolysis to convert their H2O water into HHO
water, which, when burned in the torch, produced simple water as exhaust.

Nowhere did they actually explain the difference between "H2O" and "HHO"
water. They also didn't actually say they produced more energy than they
used, but between the reporter's excitement and the careful statements of
the promoter, you would certainly get that impression. 'Free energy from
ordinary water!'

I like this Bussard widget, which is supposed to be a super-effecnt
Tokamak fusion reactor design:
http://www.centauri-dreams.org/wp-content/uploads/2007/01/bussard_fusion.jpg
They had something just like that in John W. Campbell's "Islands Of
Space" from 1931, with solid electricity stored inside of it.
I assume it's made out of Relux, given its shiny silver exterior.
Me, I want my polywater, and I want it now! Think of all the expense and
time saved over making Jell-O by boiling water, adding Jell-O powder,
and then chilling it...if you could just stir it up by adding the Jell-O
powder to cold polywater.
Okay, it would look like snot, but it would taste the same (as Jell-O,

 Not at all related to a Tokamak- doesn't even work on the same
principle (magnetically confined plasma).  It is more closely
related to the electrostatic confinement fusion devices
originally patented by Philo Farnsworth (whose enduring
invention is the electronic television tube) in the 1960s.

  Dr. Bussard passed away earlier this month, but I believe that
the project has recieved funding to continue research and
development from the US Navy.

Around 25 years ago, I saw an ad where you could buy your own Norden
bombsight for just a couple f hundred bucks; I wish I had picked one up,

Despite it's alleged accuracy ("Bombs in a pickle barrel from 30,000

The only Revi's I've ever read about were gunsights, not bombsights.
You could use them for dive bombing, but that wasn't their primary purpose.
They used the Lofte bombsight for level bombing.

Hard to believe, since they were almost still in use 25 years ago.

[Last use was USN VO-67 in the late '60s and early '70s.]

:Despite it's alleged accuracy ("Bombs in a pickle barrel from 30,000

You exaggerate in the other direction.  The Norden was generally
spec'ed to put bombs from 20,000 feet into a 100 foot circle.
Operationally it was somewhat worse than that, but "lucky to land
within a thousand feet of the aimpoint" is simply wrong.  It did much
worse in the Pacific Theater than in Europe due to bombing from 30,000
feet (vice the 20,000 feet it was designed and tested at) and because
of jet stream effects.

Hint:  The Norden had inputs for crosswind effects.

The dummest case I ever saw of over-classification occurred back in
seventies.  There was an international conference on nuclear power- I
think it may have been specifically on fusion.  It was hosted
somewhere in this country-forget where.  A Russian physicist was
invited to give a paper on his work on laser containment fusion.  The
DoD objected- that topic was classified- and went around collecting
pre-prints the guy had sent out.

Now, being both ex-military and a retired aerospace R&D engineer, I
certainly understand the need for secrecy in some cases.  The problem
is that the service security agencies have no real idea of the reason
for such security and end up classifying the WRONG THINGS!  They are
trained in document security, spying, and such, but NOT on WHAT needs
to be classified and why.

Supposedly in the R&D arena it was up to the scientists and engineers
to define what would be classified, but there were customer (military
services) guidelines, and they frequently made no sense.  They had no
idea what parts of a new technology should be classified and what
shouldn't.

The biggest reason for military security is to not allow your
opponents to draw up a clear line of battle classification and know
the effectiveness and numbers of your weapons systems. How to build
them is NOT the big thing.  Most halfway developed countries can
develop them themselves. It is knowing what we are ready to deply, its
effectiveness, and our numbers of them, that is the real thing we need
to conceal.

We need to keep secret the speeds, max altitude, range, payload, of
our latest fighters, not how to build them.
Fred J. McCall - 29 Sep 2007 16:55 GMT
:Supposedly in the R&D arena it was up to the scientists and engineers

What country was that in?  Certainly not the United States, where only
government officials have what is called 'original classification
authority'.  It is certainly never "up to the scientists and engineers
to define what would be classified".

:... but there were customer (military
:services) guidelines, and they frequently made no sense.  They had no
:idea what parts of a new technology should be classified and what
:shouldn't.

Again, not how it works.  Folks with original classification authority
produce a Classification Guide, but it's not 'guidelines'.  It
mandates what is and is not classified.  Every case where it is "up to
the scientists and engineers to define what would be classified" is a
case of what is called 'derivative classification' and traces back to
that program classification guide.

See Executive Order 12958 (April 17, 1995) for latest guidance on this
subject.

I know a bloke here who ran a hydrazine-fuelled rocket kart at the
drag races here in Perth until he found he couldn't get any more
hydrazine from his supplier in the USA - it had suddenly become a
prohibited export. This was back in the mid 1980s I think.

I find that pretty unlikely, particularly to Australia.  Got a cite
for that?

Why didn't he just buy it somewhere else?

Considering the lethality of the stuff, I'm surprised a civilian could
ever get it at all.

I just find it funny that nobody is complaining about CHINA'S export
restrictions on UDMH and such.  It's only the US that comes in for
bashing...

Hey, anything China doesn't export is less competition for American
workers!

And they sell to people who are not nice, so if they really do refrain
from exporting some nasty stuff at all (and aren't just making it up)
that would be good too.

Also, the U.S. is believed to have the top technology in the world;
only people living in poor countries are deprived if they can't even
get ahold of Chinese technology; all the rich countries ought to be
able to do at least as well as China.

Good question.  I speculated it may have been because of its large,
deployable antenna.  But after talking to a friend who used to work at
Harris (they made the thing), it still seems silly.  The easy part about
making such an antenna is deciding what shape it needs when deployed.  The
hard part is getting a structure designed so that it will deploy and
(eventually) settle down to its final shape, which has to be very accurate
and precise.

The guys I know who used to work at Harris are still upset at what JPL did
to their antenna.

I'd think we would _want_ or enemies to copy Galileo's antenna design. ;-)

Oh yes, that mess... well they just wanted to see how it worked, that
was all. Okay, so maybe it got a little bent or something when they were
looking at it....but they won't ever do that again, they promise. :-P

Many years ago, prior to 9/11 I requested Voyager blueprints from JPL.
They obliged with no objections. I have it to this day and treasure
it.
