Subject: RE: Added info re three missing in WPB

I've got a question/suggestion.  I don't dive with OMS wings but a
friend does.  Since reading the list I've thought about "what/if" he had
a problem.  Although I've never tested it, because he'd get pissed, I've
always thought if he had a lift problem I'd just cut the bungee thinking
it would allow more air to effortlessly enter the wings.  If this works
then why didn't someone with loads of experience cut the cord?  I'd
think this would be the easiest way to "solve" the bondage problem if
only in an emergency situation.  Now if I were narc'd on nitrogen then
maybe I wouldn't think to cut the bungee.  If this solution won't work
then sorry and please explain why.  I've only seen these wings and never
used them.

Thanks way in advance and hope it's helpful,
Safe diving,
Art.

	Wings with bungees are ridiculous- they will exert pressure
against the
	inflation, and cause the opv to dump well below what the ambient
	pressure would. They are obviously going to present a massively
	dangerous static lung load if you try to inflate them manually.

	 If you tie them too tight to start with, which many of these
dopes do
	because they think it is less "drag", they will not give much
lift.
	There have been other acidents associated with this, so I
believe they
	are now shipped out without the bungeess tied, so this is done
at the
	dive shop, or by the end user. Hmmmmmmmmmmmmmmmm...........

	 The drag issue is realy FAS - the bungied surface causes
massive vortex
	shedding and increases drag, not to mention the entangling
capabilities
	of all of the bungee and other dangling stupidity associtated
with these
	wet dream wings. If you have to add volume to get lift, it will
be the
	same volume on any wing, so you want the wing whos shape most
closely
	conforms to the gear, as does the Dive Rite wing which lays
tight to the
	tank and wraps up around it, with smooth surfaces, already in
the slip
	stream.

	 There is also the problem of two inflators on some of these, a
real
	boondoggle . You can immagine the degree of clustery that get
set up
	with that arrangement.

	 The fact is that if you dive the right gear to start with, none
of this
	tekkie stupidity is necesasry. If you dive steel in the ocean,
use a
	drysuit. If not, use aluminum tanks. Real simple, real
efficient. 

	 If you dive in the ocean, use aluminium deco bottles. Real
simple. We
	found this out a long time ago, we execute these dives with no
problem,
	and you can ask Capt Jim Mimms, he has watched this for years,
as have
	his predecessors and succesors in the dive boat business. My
guys cause
	no problems other than hammering the strokes on the boat.
