Not sure, but Hannah certainly is.
BTW, I spent some time this weekend re-reading Ground
Forces. The sidebars alone are well worth the purchase price.
I was also re-reading GURPS Traveller (and GURPS Vehicles).
GURPS Traveller has a lot of what I call "'splainin'"
I know that there are individual sourcebooks coming out on
Nobles, etc. But is there going to be one "meatier" general
Traveller sourcebook?

Hm...well, in practice, 'surface pressure' = 'mass density of atmosphere' *
'local force of gravity', so if you want you can use pressure/gravity. In
practice, pressure is probably close enough, particularly at the level of
detail likely to be present in Traveller.

Hey gang, I sent this to the TML a day or two back, but was really unsure
if it ever *actually* got to where it was going; hence this repost. If
you've already read it,by all means, please ignore :)
Hi gang,
Well, I missed the end of the Turokan Character Derby by a bit (oh well),
but there’s no reason to let THAT stop me.
The following is in answer to Larsen’s request sometime back that I make
a character using my recently-worked-up ‘Commando’ Career.
Neff Ogawbayawnawquot
Neff grew up in the barrios of the ‘Cheap Quarter’, a ramshackle
neighborhood butted up-against the Downport’s Loading Docks, at the Eastern
edge of sprawling ‘New Aberdeen’ on ‘Hellas’ (A-8898AC9D-N, Outer Rim,
0702). As a youngster, Neff did piece-work helping Marine crews load cargo.
While accredited union-backed stevedores would have probably broken Neff’s
hands for unauthorized work had they caught him, the Marines, on the other
hand, were much friendlier; paying him with a few Credits, ‘Morkebla
Morrabrod’ cigarettes, or with bits of cast-off equipment. Once Neff’s
mother found out he’d been spending a lot of time with the Marines, she hit
on something of a scheme, and soon Neff was selling them batches of his
Mother’s homemade Fry Bread.
Not too surprisingly, Neff joined the ranks of the Imperial Marines.
Private Ogawbayawnawquot took to the structure of Marine Life well, and
exhibited quite an aptitude for his General Quarters assignment; that of
gunner for the #3 port Laser-turret aboard IN Cruiser ‘Blue Mountain’.
Almost a decade later, Neff had risen to the rank of Captain. During the
eighth year of his 12 years minimum service, Neff was seconded to Special
Branch; his knowledge of the arcane and little-known language of the Ojibwa
being noted as something of a desirable asset.
Meeting the stringent requirements for acceptance, Ogawbayawnawquot
became an Operations Officer within a Combat Applications Group; and over
the next dozen years was involved in a number of rescues, retrievals,
counter-insurgency and other ops; being promoted to the rank of Alpha-level
Operator along the way.
Neff’s team was involved in the much-publicized (and subsequent subject
of the hit Tri-V feature and popular game) intervention at Tethis Highport,
where a group of disaffected Miners were holding the customers and staff of
a ‘Galaxy Pizza’ hostage in protest of the pizza chain’s parent-Corporation,
Nguyen-Baurhaus’ recent purchase of the entire Tethis Asteroid Field, and
the requirement that anyone outside of their own in-Corp mining concern
working in the Field had to pay both a hefty registration fee, as well as a
20% cut on all finds made. When negotiations between the Starport
Authorities and the Miner’s leader, noted anti-Imperial separatist Nathaniel
Rosen broke down, and he really started talking crazy, members of the team
who’d entered the restaurant through maintenance access-ways, went into
action.
When ‘Trevor the Turtle’ (with his plaid shell); mascot of ‘Galaxy
Pizza’, stepped out of the apparently empty storeroom with a pair of his
equally-cute ‘Pizza-Eatin’-Pals’, Rosen was heard to utter “What the Fu…?” (
a phrase much-quoted since; usually by separatist-crank-types in reference
to Imperial excesses) before a heavy DP gauss round, fired from an Operator
waiting motionless a few hundred meters off the Highport in zero-g for the
last 17 hours in jet-black combat armor, made a neat, tiny hole through the
restaurant’s armorplast window and exploded Nate’s head, while the inside
team, still in mascot-drag, busily double-tapped any opposition.
As the air hissed out through the holed armorplast, and various iris
valves went about their automated business of closing, Rosen’s wife, Sarah,
huddled among the customers and employees on the floor, threw the switch on
the micro-detonator she carried after seeing her husband’s head come apart.
The charges the Miners had placed on the Port’s outer hull had been removed
and deactivated in secret, but the heavy charges strapped to Rosen’s body,
and covered by his battered Vacc Suit, went off without a hitch.
The armorplast window, though badly spider-webbed by the tremendous
blast, actually held; allowing Emergency crews to quickly get to and help
the survivors, instead of the much-more unpleasant duty of trawling space
for floaters.
Ogawbayawnawquot was frankly surprised to find himself alive and awake a
few months later aboard the IN Hospital Ship ‘Kahanamoku’. Superiors had
apparently decided that, even dead, he was a positive asset to Special
Branch; so Neff was repaired, improved, regenerated and returned to life;
returning from the other side with a re-constructed torso encased in TL 14
Combat Armor-equivalent; protecting several bionic organ-analogs.
He returned to service with Special Branch a member of their ‘Enhanced’
unit, and served another 12 years, with a final rank of Beta-level Operator
before finally retiring from Military Service.
Neff Ogawbayawnawquot

* Several of Neff’s internal organs have been replaced by bionic analogs;
providing a hearty +15 END; giving a total of END 27(T). It also toughened
him up with the equivalent of AF 6. This 6 AF added to his Combat
Armor-equivalent’s AF 14, gives Neff a total AF of 20.

Linguistics-1, Brawling-0, Grav vehicle-0, Computer-0, Cargo Handling-0.
Notes:
A tall human male, Neff is a descendent of Indigenous Peoples of Old
Earth’s North America. He is powerfully-built, with weathered copperish
skin, and keeps his graying hair close-cropped. He is quiet and thoughtful,
and usually keeps a distance from anyone new until he has gotten to know
them.
Years of constant travel have prettymuch ingrained Ogawbayawnawquot with
a serious wanderlust; making it practically impossible for him to settle
down in any one place for very long; hence he’ll usually to be found
knocking around Port, trying to line-up a gig as a Gunner or Security
Officer in hopes of boosting out with some good people and get moving again.
He’ll only hire-on to a Ship which either also hires-on, or allows him to
bring along as family, his sharply-dressed Aslan companion, Quamm.
When not on duty, Neff remains quite the character; an insufferable
prankster and, when he does speak, a bad-punster as well.
Neff is able to recognize trouble coming at a pretty fair distance, and
will not sign with anyone appearing to be an ECM or someone of their ilk.
Once he’s signed-on, The Gods protect anyone who attempts to mess with “his”
Ship. Pirates get the old turret #3 treatment on approach; and should any
be encountered who are still breathing inside the Ship, they’ll be Spaced
ASAP. If there isn’t enough time to carry out this action, the Pirates will
be summarily executed. The same holds true of Hijackers.
Neff will usually be found dresses in one of the heavy, padded,
multi-pocketed and hooded, chocolate-brown ballistic body suits popular with
members of the ISS. He carries an auto-snub pistol with built-in
targeting-laser, loaded with homemade ammo in a shoulder-rig. In addition,
he owns a chopped-down, stockless 11mm ACR with built-in targeting-laser
which he usually carries in a satchel bag, with 4 magazines of ammunition,
as well as a super-dense, folding trench-knife, a heavy monkey wrench, a
roll of duct tape, a 6m roll of sticky-backed strip explosive, 6 magazines
of 11mm ammunition for the pistol, a jumbo pack of ‘Morkebla Morrabrod’
cigarettes, and a large package of chocolate-covered coffee beans in
assorted pockets.
Neff speak Anglic and Ojibwa, and has learned his long-time companion
Quamm’s native Aslan.
With close to 40 years spent as a weapon, Neff doesn’t give a second
thought to casually and efficiently kill an enemy with a minimum of wasted
time or action.
Notes
You may have noticed that both the sex and exact relationship of Neff’s
companion Quamm have been left ambiguous. By all means, someone feel free to
work Quamm up if you like :)
And, as usual...
The author grants rights to anyone to use this post in anyway they see
fit.
Best.

They were bad enough on the few occasional that the wind blew from the north.
at the time I was working in a facility were over 50% of the building (including where
I worked) was clean rooms of one level or another.
The ash got into all *sorts* of places.
I'd make volcanic ash a candidate for "insidious" atmosphere.

Rainier, up by Seattle is more likely though. And the most likely "weak spot" there is
aiming at Puget sound (with a few places like Seattle & Tacoma in the way).
the likely weak spot on Hood is on the south flank. Which points at a whole lot of not
much.

Alas, for some of us, that's not a joke but rather something we have to be careful
about.

Sound's more like the girl from the third one of Ringo's Posleen War books. At least

If he needs to get into the ship (or compartment, in case of a holed ship) badly
enough, he'll take it off. Suits with any sort of leak handling capability will just seal
at the wrist.
I seem to recall that Col. Kittinger, the record holder for high altitude parachute
jump (102,800 feet!) lost one of the gloves on his high altitude suit (defective
sealing ring)
The symptoms were swelling and edoma. And some burst capillaries. Other than
the burst capillaries, he was fine in a few days (as I said, about as bad as a medium
case of frostbite).
Skin is *tough*.

This has already been covered by someone else. The pressure difference causes a

I'm assuming "unanticipated" situations. Things like needing to use a fingerprint
scanner in a holed compartment. Or someone foolishly putting one on the outer
door of the main airlock.
People *do* make mistakes that stupid. One of the biggest hospitals in New York
had a brand new back-up generator when the 67(?) blackout hit. the chief engineer
confidently reached out and pushed a button. And nothing happened. It had an
*electric* fuel pump. And no battery.
Another had a generator that cut in automaticly. But the generator was in a sub-
basement next to the East River. And the sump pump *wasn't* one of the pieces of
equipment on the emergency power board. So it quit when it got flooded out.
Security concious players *will* make goofs. Or run into things in abandoned ships
or bases.

Well, it causes fluid accumulation, which causes problems in the affected area, but
even minutes of exposure is mostly painful with some temporay loss of function.
Kittinger got out of it ok. And he was exposed for a number of minutes.

Well, that *is* one way of looking at it. But if the crewed areas get above 350K, it
really won't matter much anymore. <g>
The way I generally look at it is like this:
You have X area of radiator with a max service temp of T.
At that temp, every square meter is radiating Z watts. So the maximum amount of
heat you can get rid of is X * Z.
At lower temps, the heat flux is lower (ie fewer watts/m^2).
Getting rid of heat from the fusion reactor and some other systems (such as some
weapons) is "easy" as their operating temps are *higher* than T.
Just use some convenient fluid (gas or liquid) to transport the heat.
For systems that have to be kept at *lower* temps than the radiators (the crewed
spaces and the LH2 tanks) you have to use heat pumps. Which contribute H watts
of heat per watt of heat they pump. the value of H depends on the difference
between the desired temp of the system, and the radiator temp. the bigger the
difference, the more energy is required (and it *all* winds up as heat eventually).
So there is a temperature differential for which *all* the capacity of the heat pump is
used up in getting rid of the heat it generates by running.
I rather suspect that LH2 tanks are *well* insulated and may have their own,
separate radiator setups.
I also suspect that the most common tactic for getting a ship to surrender (if it can't
run away) is *diffuse* beam laser fire. Every joule of heat it creates in the hull has to
be gotten rid of. At the expense of using power to run ship systems.
The crew has a choice between surrendering and baking.
