	Honestly, I'm not sure about the mothballs.  I suspect that they 
would not help.  I checked some references, and drew a blank.  You are correct
that Napthalene is used in mothballs (as is para-Dichlorobenzene...you have to
read the box).

You are correct that the nitrocellulose in the smokeless powder will burn with-
out any other chemicals. That is because the reaction is a decomposition, and
no additional oxygen is necessary. The same is NOT true of acetone. Additional
oxygen is necessary before it will burn.

It may, or may not, continue to burn when immersed in water. It depends on a
number of variables. In most cases, it would not form a large/stable enough
air bubble (or burn hot enough) to keep burning when submerged.

Not surprising - many things sound like they will work - if you have very
limited knowledge of chemistry.

See above. You really should verify such things - before posting them.

Smokeless powder - whether mixed with acetone or not, is an explosive.
It deflagrates fairly slowly, if not confined. Confine it, and it burns
very rapidly - as in a firearm cartridge. Initiate it with a strong enough
blasting cap, and it will detonate.

I'll probably buy a Cypres when I buy a rig but not after having
a good look at the cutter.

Cutting steel cables proves little if you want to cut a closing
loop.

Another article mentioned Kevlar closing loops. I recall cutting 
some Kevlar cable (3/16") once using side cutters and metal shears
FOR ABOUT 15 MINUTES. Steel cable would have been toast in seconds.
I later found out very sharp scissors can do it in a COUPLE chomps,
the scissors also end up getting dull very fast.

Those cruddy little hairy sonuvabitch Kevlar fibers will try their
damndest to slip between the edges of the cutting surfaces, steel
strands don't stand a chance. It probably wouldn't take a whole 
lot of Kevlar strands to keep the spring from popping the reserve
flap.

My only point is that tolerances are critical here and would not
show up when cutting steel. I'll also speculate that closing 
loops were never designed to be cut.

ANOTHER OPINION:

I feel that it all depends on what you're used to doing.  Most of my
personal experience is solo, and indeed, when there are others in the sky
with me (RW), I feel less aware of my altitude and look more often.  If
Robin is not used to doing freestyle, I think that an AAD and/or Dytter is
a good idea as backup.  (Personally I feel that a reliable AAD should be
used on most kinds of jumps)  On the other hand, Mark does lots of
freestyle, his head may be set for the time/alt awareness of that kind of
dive.

I have a Cypress AAD for 2 possible scenerios: 
					1.	in-air collision. (slip and hit the step, head to head freefallers,
							 freefaller and canopy,...)
					2.	over concentration on a task. ( the last point of a dive, geeking
the
							 camera, or chasing to help another.) 
I like the fact that the Cypress lets you take it lower than standard pull
to clear others or help out, but it will keep you from making a second
hole. 
 



?? Does anyone heard of a mis-firing of a Cypress??  As I hear it, that is
a major reason why people didnt like earlier AAD's (Sentenal, FXC,...).

?? Any other reasons you wouldnt use an AAD (other that cost) ??

Why?  Because you're alone and don't have anyone to fall back on in case you
do lose alt awareness...?  Hmm...I've done probably 100 freestyle jumps, and I

Yeah, 600 foot openings were good for Bill Crago, too...

until one day when he had a pilot chute hesitation, and went in.
(Michigan, 1972).

The equation describing risk in jumping contains multiple variables,
not just one.  Anyone who thinks they have total control over every
thing that happens in a jump just by "having their head together",
is only fooling themselves.  Equipment can, and will, occasionally do
wierd things, and intentionally eliminating time to deal with it isn't
what I classify as "very intelligent".

Hi Dan!  
This incident should remind us to be responsible for our own
safety.  It's too easy to feel confident that when you're with a
high timer like McGowan, you don't have to watch your altimeter 
because he'll never let you down (no pun intended). I've never 
met Mike but I'll bet that as the senior jumper he feels pretty 
lousy about letting the dive go to its fatal conclusion. 

>...  I wonder how Mike got sucked down to 500'?  That sounds almost

			  ^^^^^^^^^^^^^

ARGH! Don't even think that!  You might start believing it yourself
when _you_ get mega-jumps, and then......... :^(    Mike McG almost went
in himself!

Absolutely correct, which is why (if all these facts are true) I think
McGowan lost track too. Guess we'll have to wait to find out what happened.

And Piras incident added another knowledge of how badly things can go.
For me, it was impossible to imagine that the jumper of his experience
can get killed by premature deployment of the member of his own
skydive which is as small as 4 way.  If it is like in the middle of
100 way, that's one thing.  If it is from other group, who left plane
after him, didn't leave enough separation and freefall through his
canopy, that's another thing.

My reasoning would be that to get killed directly by hitting
prematurely opening canopy, somebody have to open right below you,
with enough distance that there will be enough difference of speed to
impact.  How could a guy with 13000 jumps would put himself in that
kind of situation in 4way? 

According to skydiving magazine, one jumper in his 4way was about 30
feet below after exit.  When Piras was signaling to other two jumpers
to get down to the low person, low jumper's pilot chute slipped out.
(It was attributed to small zeroP pilot chute which replaced old bulky
one.)  The opening canopy caught his leg and threw him off (which I
assume didn't have any damage on him), AND his head hit the knee of
the other jumper, which knocked him out.

I thought I had some idea that shit happens.

Or that it might mess up his hair. I have seen people make such comments
though I can't see how a hat or helmet messes your hair up worse than
the air does. I like protec's I've had a few bad scraps in mine that I'd
not have been happy if it was me instead. Same goes for gear, some
people who own two or three rigs wouldn't jump the unclassy rig that
is built for the conditions or location, and jump the flashy hot rig
that jepordizes them and the image of  the sport. Why some of us do that
makes no sense but I think it is a part of why some people jump.

the phone number and any details on the closest DZ to Palm Springs?  I have
heard rumours of a seasonal DZ callde Hemmet (sp).

Any info appreciated.

PS Anyone have the numbers to Elsinore or Perris Valley?

Thanks in advance
