Re: [PSUBS-MAILIST] Dif. Between Ambient & 1ATM

["Sean T. Stevenson" <cast55@telus.net>]

I guess what I was trying to get at was that with an ambient design so
configured to deploy divers, you aren't gaining significant advantages over
simply putting divers in the water to begin with, from a mission duration
perspective.
