It does say that they have to be secured somehow, or in a rack.

That's so's we don't knock them over with our fire streams and bust their
little heads off. Picture it. Firefighter crawls into burning room. Opens
nozzle. Tanks falls away from him. Valve busts off when it hits floor. Tanks
returns favor back at firefighter. Ouch!

Did you se the Mythbusters episode where they decapitated a cylinder and it
whooshed through the concrete block wall?

Other than that, the reason to use an Acetylene cylinder while upright is
that the Acetylene is dissolved in Acetone which is then infused in
diatamacious earth within the tank. If used in anything but a vertical
position, the Acetone may escape through the piping and hose.

More on acetylene---T.A. Wells,Chief Engr. for Beech, says, carryover of
acetylene into a weld will contaminate it--He also stated, leave a small
% in the cylinder to prevent rapid boil-off & carryover at the last
moment of use.

He wrote a teriffic book--Well's Manual of aircraft materials and
manufacturing processes.

I saw that episode and I honestly thought it would have done alot more
damage then it did. Urban myths had tanks traveling thousands of feet
and going through poured concrete walls with ease.

Yep; and that confirms what I had heard, before.

At one time, I had a co-worker that was known for telling tall tales. He
had a doozie about the valve being broken off an Oxygen bottle, that I
didn't quite buy in its entirety. I don't recall exactly what it was now,
but I didn't have a problem with the basics of the tale.

That might be possible with an optimum sized hole, and nozzle, but even
then, the weight of the container is substantial. If it were a light
container, it might accellerate quickly enough to build some momentum.

Poured concrete with rebar is probably above the realm of obtainable,
though. g

Wonder if Moller could use a bunch of NO3 bottles as a "ballistic
parachute"? Trigging them off would arrest the fall and render witnesses
inert and happy.

As are we all. We believe that we're beginning to understand the
issues and can deal with them, but obviously I can't say anything
until the full report(s) are released.

... I thought you might be able to at least say what the time table
for results is likely to be.

Nope - sorry.

Well, good enough; it will have to be. I am glad to hear that you are
starting to understand what happened, and how to work around it.

Understand, that many of us think the work Scaled is doing is way too cool,
and are very interested in what is happening with your programs. I wish I
had some expertise that would make me employable at Scaled, really! g

It is with that interest that I wondered how things are going with the
investigation, and Scaled attempting to get things back to normal.

Good to hear from you, and looking forward to the "next generation"
spaceship showing up at OSH! :-)

The devil would be in the details, though.

Imagine that the (insert here, whatever his little "tether bound" Jetson's
car is called) is upside-down, right close to the ground, and the bottles
fire.

Ouch?

Not that they would have enough power to stop the fall, even if they were
upright, anyway.

Inverted fired bottles would be a nice touch, though. Kinda' like spiking
the football after a touchdown, if you can conjure up the mental image! g

I was in the tower at Wright-Patterson AFB many years ago. There were a
bunch of F-102's doing touch and go's just about sunset. The afterburners
were clearly visible, throwing ten foot long flames as they went around.

The controller suddenly grabbed his mike and hollered, "Aircraft on short
final, your gear is up! Go around, GO AROUND!".

The F-102 grabbed a handful of stick, pulled the nose almost vertical and
shoved the throttle to the stop. As the attitude passed vertical, I saw the
engine blow parts out of the nose and tail simultaneously. The plane
continued it's rotation until it was inverted, flying backwards a few feet
above the runway.

As it settled lower, the pilot ejected. He didn't quite clear the cockpit
when the whole thing impacted. It slid a long way.

The next day, my brother took me for a ride in a TF-102 to clear my head. It
worked.

Once upon a time, one of our firefighters was setting down his SCBA
bottle (for firefighter breathing apparatus) and made a single error of
omission. He had an OLD bottle with a rounded bottom, instead of a newer
bottle with a flat bottom. Flat bottles stand upright.

This one fell over, striking the valve stem. It hop skipped and jumped
100 yards to the treeline, then ricochet'd around in the forest. Nobody
was in the way.

That is too ugly to hear about, let alone, having to see it happen right in
front of you.

I imagine the ride helped, but that you can still picture the whole thing
playing out in your mind's eye, in vivid color, even today.
