don't know about NY, but here in Colorado we jump all winter. if it's 30 F
on the ground, I'll go up. i wear expedition weight thermals (uppers/lowers)
plus sweat-pants, and a turtle neck and a sweatshirt. and bicycling gloves.
never covered my face, but i will probably get a thin mask. the coldest 
exit i made last winter was between -5 and 0 F. it was miserable in the plane.
wind chill factor is negligible with winds above 40 MPH - at 0F with wind
chill figured in, the temp is about -40F as i recall. my suggestion it
to dress for the plane ride - i never noticed being cold in freefall,
except maybe my finger tips.

Considering recent events in Illinois, it might be worth clarifying that
the above statistics do not include aircraft fatalities.  They are above
and beyond what "Parachting Magazine" calls accidents during or after
exit of the aircraft.

So, can I put you down for a nice wool sweater? :-)

OK, here's a plan: pay for the entire AFF course up front, if you can.
pay attention in ground school, ask lots of questions, read the FAQ, 
buy your beer, post lots of articles here, buy the Skydiver's Info 
Manual (or SIM) from the DZ, learn all the rules and don't you ever
even *think* about maybe having a dream about breaking them, at least

I agree that the only thing the canopy sees is "forward wind",  but I think
I'd have to agree with the first poster that turbulance is a differnet story.
The canopy is a mechanical system, and cannot react instaneously to sudden
changes in the r-wind (IE: turbulence).  I beleive that this, in theory, could
collapse cells, but I dunno if the normal turbulence we see in the atmosphere
is enough to cause this (IE: anybody  know if this ever presents a problem?).

Newsgroups: rec.skydiving

As long as we're talking about dreams, here's one of mine.       

I'm skydiving and I get so engrossed in the dive that I forget about pulling.
At the last second I look down at the ground and see that I am going to 
bounce.  At this point I'm not scared, just pissed off that I forgot to pull.
My dream then takes a 3rd person viewpoint, ie. I "see" myself going in, 
as if watching from a TV camera on the ground.  The only thing is that I
don't die, I literally bounce.  I hit the ground and bounce up and down 
like a basketball.  I stop bouncing after 4 or 5 times and I'm uninjured.
I'm just really embarrassed and afraid that the DZ owner will ground
me for not pulling.  I quickly get to my feet, dump my main, wad it up 
like I just landed, and try to act as if nothing happened.

Blue skies,

Perhaps what you mean to say is that airspeed always stabalizes to
the same speed -- it varies only immediately after the opening the
canopy or during turbulant conditions.

Date: Tue, 15 Sep 1992 18:52:40 GMT

I'm about ready to order a new rig.  I've tried all the small Sabres & Novas and
have settled on a Sabre 107, in a Flexon.  I am a little less confident in my
choice of a PD-143R reserve.  At 155 lbs. + 13 lbs. of gear (guestimate
not counting main), this would put the reserve wing loading at 1.17.  PD says that
it isn't a structural integrity problem, but that it would be a slightly faster
landing than they would "normally recommend".  However, being an experienced
jumper (1500 jumps) that uses a small canopy as a main, it doesn`t seem too far
out of the norm for me.  Has anyone on the net ridden a PD reserve with similar
wing loading?  By the way, I only intend to jump this rig when conditions would
permit landing a Sabre 107.  I'm keeping my other rig with a Sabre 170/PD 176R for
tight landing areas and hot no wind days when I want to be lazy.  Any comments
from people that have used their PD reserve?

Also, I'll insert a shameless plug for skydiving magazine who used a few of my photos
in their September issue, including the section 2 cover photo!

     That might have been me.  I originally read it many years ago
in a magazine (Sky Diver, perhaps).  It was part of an article
entitled "Snappy Answers to Stupid Whuffo Questions" (obviously
a takeoff on Mad contributor Al Jaffe's articles of nearly the
same name).

     This one, though, I believe is mine:

Q: How do you breathe in free fall?
A: I don't.  I take a deep breath before exit and hold it all the
    way down.  Students start off at lower altitudes because they
    haven't learned to hold their breath long enough yet.

Well, I don't think the argument depends on differences in wind speed at 
opening alt vs exit alt. 
I do somewhat agree that "ground speed" can be misleading, but maybe
we could say "The rate at wich the aircraft is penetrating the wind".
This is, however, directly related to ground speed.

Well I sure can't make it Indiana.  Its just a bit out my way.  But
I'd real interested in the "rules" and the methods of judging.

There is a guy here who is keen to organize an event like this.  Just
as soon as he can work out a way of running it without killing all the
participants.  His latest idea is to put a foam rubber wall on the
target and have everyone demonstrate their ability to surf, then jump
the wall.  He called it "show-jumping".

It sounded awfully silly to me (and everyone else).  So if you have
some sane rules I'd much appreciate it.
