Well, his brain may die from blood starvation, but he's going to end up
with the biggest feet you've ever seen. :-)
In the early Navy Space Cruiser design studies, the astronaut has going
to go up feet-first, which sounds like a really good way to get an
aneurysm in your brain:

Though technically not correct, many people do refer to either
propellant on a liquid fuel rocket as "fuel" rather than "fuel" and
"oxidizer".

I don't have a problem with that, but unless I've managed to overlook
it, there's no mention of anything else that would be oxidized.

Hey, it's better than "Manda", the other crappy giant snake monster out
of "Atragon"*; which was about as threatening as having Kermit The Frog
getting heavy on your giant flying submarine's ass.
The scene where they open the giant creaking iron door down in the Mu
Empire, to reveal that thing's ten foot diameter ping-pong ball witless
eyes peering at you is something you will never forget; proving spending
around 95% of your whole movie budget on the model giant flying sub,
leaving the monster to be stuck together on pocket change, is not a good
idea.
But to hit the low point though, it's probably the US, not Denmark or
Japan, that did it - with "The Giant Claw":

Terrifying giant rubber vulture marionette.
Oddly enough, that one did _not_ get its own comic book. :-D

But then, other countries made bad science-fiction movies too. Thus,
clicking on various related links to that video, I found "Journey to
the Seventh Planet", an American science-fiction movie starring the
immortal John Agar.
One of the other stars of the movie was Danish-born actress Greta

notes _five_ Danish science-fiction movies. "Heaven Ship" from 1917 is
one of the earliest ones made anywhere. Of the three others beside
that and Reptilicus, _two_ are welfare-state dystopias, Selvmorsskolen
(Suicide School) and Manden der ville vaere skyldig (The Man Who Would
Be Guilty), the other one is Manden der taenke ting, about a man who
could materialize objects with the power of his thought.

Denmark. But the Danish-language version of the film, in which the
American actors instead of the Danish ones would have been dubbed, was
never released and has been lost.
Apparently Greta Thyssen only moved to America *after* this movie to
pursue a Hollywood career - which was short-lived. She is mainly
remembered for appearing in several of the Three Stooges' films.

I'm sure what Sylvia meant was that liquid oxygen can be used as a
propellant, but its role is as an oxidizer, not a fuel. (I find myself
wondering, what could you use to oxidize oxygen? Fluorine? I think
as liquids they're miscible in each other, giving you an improved
oxidizer when compared with LOX without the F.

Neither Google nor IMDb seems to be aware of the existence of that
movie.
However, a search in IMDb found that there are now 54 movies with
country of origin Denmark and genre Sci-Fi.
"Et skud fra hjertet" is said to have only been seen by 3000 people
before being pulled from distribution; one of those post-apocalyptic
movies like Mad Max.
"It's All About Love" included Sean Penn, Claire Danes, and Joaquin
Phoenix as actors, so it must have been a fairly major motion picture.

Could that have also been the long-lost masterpiece, I fiskene tegn?

Also in that list was a *children's* movie with a somewhat similar
theme, "Help! I'm a Fish!", about children who drink an eccentric

As it turns out, "I fiskens tegn" is the title of a book of poems
written in 1948 by Ole Wivel, so that may be a reason no movie of that
name is in the series of Danish sex comedies with Ole Soletoft.

They made some modifications to reduce oscillations on the test launch.
As for the choice of fuel, they found a supplier
<http://www.purteknik.dk/uk/>, that was willing to sign up for a
sponsorship. Even without that, the cost is only a little higher than
paraffin.
The plan is to move to HTP as oxidizer on future rockets.

I will admit to some chagrin that they haven't at least done some
centrifuge tests to see if 3 g standing up is really tolerable. They
will be putting accelerometers on their dummy at least.
However, this has given me some inspiration.
Surely some space was wasted by having the Mercury rockets circular in
cross-section. Had they been elliptical, a somewhat closer fit to the
seated astronaut could be achieved.
Further thought suggests a minor modification to the astronaut's
posture. Instead of being seated, the astronaut could be lying down
with his legs folded so that only his knees were in the air. Thus, the
blood would only drain from the knees instead of the whole lower leg.
This would only achieve a slight decrease in height, I admit, but I
presume every little bit helps.

Other payload can be put beside the passenger, as it apparently was for
Laika.
The Dane could be largely protected from G-force by filling his
compartment with water up to about mid-chest height (and providing a
chin-rest and arm-rests).
That would be heavy; so, instead, make a reasonably close-fitting "suit"
out of sheet metal, and finally fill that with water.

I wouldn't be surprised if he wears an inflatable "G-Suit" like is worn
by fighter pilots:

The test launch of the rocket is now scheduled for today (Thursday) at
the earliest, although they have a launch window that extends to
September 17th.

He'll need a hell-of-a-lot more than a G suit if he's standing up during

The Daily Mail URL has a sketch that suggests there is "Neck Head
Support." It also shows the pilot/passenger/specimen/spam in a mostly
upright position - there is bend in the knees with "buttocks support."
My question is "how does one launch a finned rocket from a submarine?
I suppose they could fold-out after leaving the tube but still... Or
is the "submarine" just that red-painted rig and it is going to launch
a la Sea Dragon?

Isn't he only supposed to pull 3 g's though (at least on the way up)?
That sounds survivable without injury if he's fairly light in weight and
in good health.
I'd be more concerned about reentry G's...on Shepard's flight his
Mercury hit a max of 11.6 G's during reentry, so I hope the top part of
that rocket is designed to come down sideways rather than nose or tail
first, or otherwise the pilot is going to be in for a world of hurt.

It lifts off from a catamaran raft towed behind the sub:
http://cdni.wired.co.uk/674x281/o_r/rocket.png
The Danes don't have missile submarines.
So why not just launch it from a surface ship or a raft towed behind one?
So if the rocket blows up, the sub can just submerge.
In fact, I suspect the sub will be submerged when the rocket launches
for safety's sake
The sub involved is so small it is nearly a minisub from the photos of it.
Apparently, they built the sub also(!):

Yeah...that old problem.
That happened on a Viking rocket also, when frost caused the vent valve
to freeze shut, and they had to go out and shoot a hole in the Lox tank
with a rifle to prevent it from over-pressurizing and rupturing.
Pat
Niels Jørgen Kruse
The plan to command the valve to shut in case of deviation from the
flight path seems a bit shaky. They better have a backup charge to blow
the LOX pipe.
