Re: [PSUBS-MAILIST] O2
Hi David,
You're dead-on about aviation oxygen. It's primary difference is the
moisture content - aviation O2 is bone-dry, which anyone who has spent 3 hours
on a high-altitude cross-country leg knows by the painfully sore throat you get
if you don't drink a little something beforehand. :-)
There may be some differences in trace gasses, but moisture is the key.
I intend to use aviation oxygen precisely for this reason - I suspect the inside
of my sub will be quite moist enough as is.
