Subject: Re: Argon Bottle to Wings?
Kevin, ideally, you would not want to put back gas in your suit, if you
can get argon from a buddy.  If you have to do it, then your BC
inflator _should_ reach the inlet if it is long enough to permit
simultaneous operation of the suit inflator.  Swivel suit inflators are
great for this, but otherwise the inlet should point to the side
somewhat.  With BC inflator connected, it will still be in an unnatural
position, but much less so than if the suit inlet was pointed downward.
 Keep in mind, that we are talking about a contingency that requires
complete wing failure, argon reg failure or argon depletion, and loss
of buddy.  Follow rule #1, and the risk is negligible.
